TL;DR
- Traditional API gateways like Kong rely on general-purpose NGINX cores and Lua plugins, introducing architectural friction and millisecond-level latency to streaming LLM workloads.
- Purpose-built AI gateways treat non-deterministic streaming, token-based accounting, Model Context Protocol (MCP) tool execution, and semantic caching as native infrastructure primitives.
- Bifrost is the top-ranked alternative, written in Go to deliver 11 microseconds of overhead at 5,000 requests per second with native MCP support, virtual keys, and complete self-hosted deployment flexibility.
- Other notable alternatives include LiteLLM for Python prototyping, Cloudflare AI Gateway for managed edge caching, and Envoy AI Gateway for Kubernetes service meshes.
Traditional API gateways designed for stateless REST microservices introduce operational friction and latency when tasked with high-throughput, non-deterministic LLM workloads. Bifrost, an open-source AI gateway written in Go by Maxim AI, is one of several modern platforms engineered specifically to handle LLM routing, provider failover, and agent governance. As enterprise engineering teams expand multi-model architectures, many are evaluating Kong alternatives built for AI and LLM traffic to eliminate plugin overhead, reduce infrastructure costs, and support agentic protocols. This comparative guide evaluates the top eight alternatives available in 2026.
Why Engineering Teams Evaluate Kong Alternatives for AI and LLM Traffic
Kong Gateway remains one of the most widely adopted API gateways for microservice architectures, but its AI capabilities function as an extension layer rather than a native design foundation. Kong implements AI features through plugins, such as ai-proxy and ai-rate-limiting-advanced, running on top of an OpenResty and NGINX core. While this model appeals to organizations already committed to Kong across their enterprise API estate, it introduces architectural compromises when generative AI traffic becomes the primary workload.
Traditional API Gateway (Kong):
Client -> [ NGINX Core -> Lua VM -> Auth Plugin -> AI Proxy Plugin ] -> LLM Provider
(Higher per-request latency)
AI-Native Gateway (Bifrost):
Client -> [ Compiled Go Runtime: Fast Path Routing + Token Budgeting ] -> LLM Provider
(11µs latency overhead)
The friction stems from several fundamental technical differences between standard HTTP REST traffic and LLM inference:
- Connection longevity and streaming: Standard REST calls complete in tens or hundreds of milliseconds. LLM responses stream tokens over Server-Sent Events (SSE) for seconds or even minutes. Managing thousands of concurrent long-lived HTTP streams through Lua plugin pipelines consumes significant memory and CPU overhead.
- Accounting primitives: Standard API gateways rate limit by requests per second (RPS) or client IP addresses. AI workloads require dynamic accounting based on prompt tokens, completion tokens, reasoning tokens, and cumulative dollar spend per tenant or project.
- Enterprise feature gating: In Kong, key capabilities required for production AI architectures, including semantic caching, token-based rate limiting, advanced guardrails, and enterprise Model Context Protocol governance, are restricted to proprietary Kong Konnect or Kong Enterprise licensing tiers.
- Agentic integration and MCP: Autonomous agents interact with tools via the Model Context Protocol. Standard API proxies lack native concepts of MCP server aggregation, tool filtering, and dynamic tool orchestration.
- Operational complexity: Running self-hosted Kong requires managing PostgreSQL databases (or complex declarative decK workflows), NGINX worker configurations, and Lua dependencies. AI engineering teams often prefer lean, single-binary architectures that boot in seconds without external state engines.
| Architecture Dimension | Kong AI Gateway (Plugin Layer) | Purpose-Built AI Gateway |
|---|---|---|
| Core Runtime Engine | NGINX / OpenResty / Lua | Compiled Go, Rust, or C++ |
| Average Proxy Overhead | 2 to 5 milliseconds per request | 11 microseconds to 1 millisecond |
| Accounting Unit | HTTP requests, status codes, bytes | Prompt, completion, reasoning tokens, and cost |
| Streaming Design | Retrofitted chunked HTTP filters | Native SSE and bidirectional stream pipelines |
| Tool Protocol Support | Enterprise-gated AI MCP Proxy plugin | Native MCP client, server, and tool routing |
| Semantic Caching | Requires Enterprise tier plugins | Native vector store integration |
| Deployment Footprint | NGINX, Lua, PostgreSQL / decK | Lightweight single binary or container |
Key Evaluation Criteria for AI and LLM Gateways
Selecting an alternative requires evaluating gateways against metrics that reflect the operational realities of foundation models rather than static REST endpoints.
A production-grade AI gateway must provide predictable routing, real-time token tracking, and enterprise-grade security controls without adding latency to model responses. Engineering teams should assess prospective solutions across six primary pillars:
- Proxy Latency and Concurrency: LLM inference is inherently latency-sensitive. A gateway must introduce negligible compute overhead (ideally microsecond-level) while maintaining throughput across thousands of concurrent SSE streaming connections.
- Multi-Provider Routing and Failover: The gateway must normalize payloads across distinct provider APIs (OpenAI, Anthropic, AWS Bedrock, Google Vertex AI, Azure OpenAI, and local runners like vLLM) and support weighted load balancing, latency-based routing, and zero-downtime automatic fallbacks.
- Cost and Governance Controls: Centralized token accounting requires virtual keys with multi-tiered budget caps, reset intervals, and role-based access control (RBAC).
- Native Semantic Caching: Rather than relying exclusively on exact string matching, an AI gateway should index prompt embeddings to serve semantically equivalent responses directly from memory or vector databases, reducing downstream provider costs.
- Model Context Protocol (MCP) Capabilities: The gateway should function as an MCP aggregator, securing and governing how agents discover and execute external tools while mitigating prompt bloat.
- Deployment Flexibility and Data Privacy: Regulated industries require self-hosted, air-gapped, or in-VPC deployments where prompts and model weights never traverse unvetted third-party multi-tenant infrastructure.

1. Bifrost
Bifrost is a high-performance, open-source AI gateway written in Go by Maxim AI that unifies access to more than 1,000 models through a single OpenAI-compatible API. Engineered specifically for mission-critical enterprise workloads, Bifrost eliminates the latency bottlenecks and operational weight of general-purpose API gateways. It delivers sustained benchmarks of only 11 microseconds of overhead per request at 5,000 requests per second, making it the fastest gateway in its class.

| [ Native MCP Gateway: Agent Mode / Code Mode Tool Orchestration ] |
+---------------------------------------------------------------------------------+
| | |
OpenAI / Azure Anthropic / Bedrock Local vLLM
Bifrost operates as a complete drop-in replacement for standard LLM SDKs: developers change only the base URL in their existing code to instantly gain resilience, caching, and governance. The gateway integrates natively with major providers including OpenAI, Anthropic, AWS Bedrock, Google Vertex AI, Azure OpenAI, Groq, Cerebras, and Ollama. Its intelligent routing pipeline features automatic fallbacks and health checks that reroute traffic around provider outages with zero application downtime.
# Drop-in SDK integration with Bifrost
from openai import OpenAI
client = OpenAI(
base_url="http://localhost:8080/v1", # Bifrost gateway endpoint
api_key="bifrost-virtual-key-prod-01", # Managed virtual key
)
response = client.chat.completions.create(
model="anthropic/claude-3-5-sonnet-20241022",
messages=[{"role": "user", "content": "Analyze system logs for security anomalies."}],
stream=True,
)
for chunk in response:
print(chunk.choices[0].delta.content or "", end="")
Beyond standard model routing, Bifrost functions as a comprehensive MCP gateway. It acts simultaneously as an MCP client and server, aggregating internal tools and enterprise APIs for coding agents and client applications like Claude Desktop, Cursor, and Claude Code. Through its Agent Mode and Code Mode execution models, Bifrost allows models to write orchestration logic that executes multiple tool calls in a single sandbox step, reducing token overhead by up to 50% and execution latency by 40%.
For enterprise security, Bifrost applies centralized governance through virtual keys, dynamic rate limiting, hierarchical budgets, and immutable audit logs. Crucially, this security footprint is not limited to servers: Bifrost Edge (currently in alpha) extends gateway governance directly to employee endpoints, ensuring that desktop chat applications, browser tools, and terminal coding agents comply with organization-wide policies via local endpoint enforcement. Organizations can deploy Bifrost as a self-contained binary, within private Kubernetes clusters, or in fully air-gapped in-VPC deployments.
Best for: Enterprise engineering teams running high-throughput production AI applications who require ultra-low latency, native MCP tool governance, complete data sovereignty, and unified control over both server and endpoint AI traffic.
2. LiteLLM
LiteLLM is an open-source, Python-based proxy that provides a standardized OpenAI-compatible interface across more than 100 LLM providers. Maintained under an MIT license, LiteLLM has achieved significant adoption among Python developers due to its broad library of model adapters and straightforward getting-started experience.
LiteLLM translates proprietary payload structures from providers like Cohere, Bedrock, and Vertex AI into standard OpenAI chat completion schemas. Its proxy server includes features for virtual key management, team-based usage tracking, and basic load balancing. Teams can configure cost tracking, set customer spend limits, and monitor traffic through a lightweight administrative UI.
Because LiteLLM is built entirely in Python, its execution overhead lands around 8 milliseconds per request under production load. For teams operating high-concurrency microservices processing tens of thousands of requests per second, this Python runtime ceiling can create infrastructure scaling challenges that require horizontal proxy clustering.
Best for: Python-centric development teams and prototyping environments that prioritize expansive provider compatibility and rapid local setup over microsecond-level proxy performance.
3. Cloudflare AI Gateway
Cloudflare AI Gateway is a fully managed reverse proxy that routes requests through Cloudflare's global edge network. It sits between client applications and model providers to provide automatic response caching, analytical telemetry, rate limiting, and fallback routing without requiring teams to host or manage gateway infrastructure.
The primary operational advantage of Cloudflare AI Gateway is zero-maintenance deployment. Developers prefix their provider requests with the Cloudflare gateway URL, passing their existing provider API keys. The edge platform automatically caches identical queries across Cloudflare points of presence, helping teams reduce redundant token consumption and absorb transient upstream API errors.
Cloudflare AI Gateway is a proprietary, closed-source SaaS service. For enterprises governed by strict data residency standards, HIPAA, or financial privacy mandates, routing prompts through a multi-tenant managed edge may not satisfy data sovereignty requirements. It also lacks support for native MCP aggregation and local self-hosted deployments.
Best for: Teams seeking a turn-key, managed AI proxy that requires no infrastructure management and benefits from distributed edge caching across public internet workloads.
4. Envoy AI Gateway
Envoy AI Gateway is an emerging open-source project under the Cloud Native Computing Foundation (CNCF) ecosystem designed to bring AI proxy capabilities to the Envoy proxy architecture. It extends the cloud-native Envoy Gateway data plane to handle LLM traffic alongside traditional microservice APIs.
Envoy AI Gateway processes requests using compiled C++ and Go filters, maintaining low latency (typically between 1 and 3 milliseconds) while scaling efficiently in Kubernetes environments. It supports basic model routing, request and response normalization, and rate limiting natively integrated with Kubernetes Gateway API specifications.
While operationally powerful for platform teams already running Envoy service meshes, Envoy AI Gateway remains in active early development. Its configuration relies heavily on complex declarative YAML CRDs, and it currently lacks high-level AI capabilities like semantic vector caching, dynamic MCP code execution, and hierarchical enterprise billing dashboards.
Best for: Platform engineering and DevOps teams heavily standardized on Kubernetes Gateway API and Envoy service meshes who want to manage AI routing through native infrastructure manifests.
5. Apache APISIX
Apache APISIX is a high-performance, dynamic open-source API gateway built on NGINX and Lua that directly competes with Kong in traditional API management. In recent releases, APISIX has introduced AI proxy plugins (ai-proxy) that allow teams to route traffic across models from OpenAI, Anthropic, and other vendors.
APISIX utilizes etcd for real-time configuration synchronization, eliminating the need to restart gateway nodes when routes, keys, or upstream providers change. Its C and Lua architecture provides high throughput and low routing latency (1 to 2 milliseconds), often outperforming standard Kong deployments under heavy traffic.
Like Kong, APISIX treats AI as a plugin layer applied to a general-purpose HTTP gateway. It provides basic payload translation and key authentication, but lacks specialized AI features such as native MCP tool hosting, prompt token budgeting, and vector-backed semantic response caching.
Best for: Enterprises looking for an open-source, high-throughput drop-in replacement for Kong Gateway that want to route basic LLM calls alongside standard microservices.
6. Zuplo
Zuplo is an edge-native API management platform built on the V8 runtime that offers built-in AI gateway capabilities. Zuplo emphasizes developer ergonomics, providing programmable TypeScript middleware, Git-based workflows (GitOps), and multi-cloud deployment automation.
Zuplo enables teams to enforce API key authentication, token bucket rate limits, and custom request transformation scripts written in standard TypeScript. Its AI features include multi-provider routing, fallbacks, and cost tracking dashboards, making it straightforward to wrap proprietary model endpoints into clean, governed developer APIs.
Because Zuplo operates primarily as a commercial, managed edge solution, it introduces operational trade-offs for teams requiring fully self-hosted, air-gapped infrastructure. While its programmable edge is flexible, complex stateful operations like semantic vector indexing generally require external services.
Best for: Modern software teams building customer-facing API products powered by LLMs who value programmable TypeScript edge middleware and automated GitOps deployment pipelines.
7. Gloo Gateway
Gloo Gateway, developed by Solo.io, is an enterprise-grade Kubernetes ingress controller and API gateway built on the Envoy proxy. Designed for large-scale microservice deployments, Gloo Gateway includes an AI Gateway module that applies enterprise traffic management, security policies, and observability to LLM interactions.
Gloo Gateway integrates closely with Istio service meshes, Kubernetes RBAC, and enterprise identity providers (OIDC, OAuth, SAML). Its AI capabilities allow platform administrators to define model routing rules, inject security guardrails, enforce token quotas, and collect metrics through standard Prometheus and OpenTelemetry sinks.
Gloo Gateway is an enterprise-oriented platform with significant operational overhead. Deploying and maintaining Gloo requires dedicated Kubernetes infrastructure and platform engineering expertise. For organizations whose primary requirement is a focused, lightweight LLM routing layer, Gloo can represent unnecessary architectural weight.
Best for: Large enterprise organizations running mission-critical Kubernetes and Istio architectures that require unified security governance across both microservices and AI endpoints.
8. OpenRouter
OpenRouter is a managed API aggregator that provides a unified endpoint connecting developers to hundreds of commercial and open-source models. While fundamentally an aggregation service rather than a deployable gateway binary, OpenRouter serves as an effective operational alternative to self-hosted gateways for teams seeking immediate multi-model access.
OpenRouter normalizes request schemas into standard OpenAI formats and handles model-level routing, fallbacks, and automated load balancing across competing inference hosts. It provides real-time pricing comparisons, usage analytics, and a shared credit balance that eliminates the need to manage separate billing accounts across multiple LLM vendors.
Because OpenRouter is a third-party managed broker, all prompt and completion data traverses its infrastructure. This makes it unsuitable for regulated enterprise environments with strict data privacy mandates. Furthermore, it does not provide local network governance, internal MCP server management, or private model deployment routing.
Best for: Early-stage startups, independent developers, and product teams needing immediate, unified access to diverse open-source and commercial models without hosting infrastructure.
Feature Comparison: Governance, Caching, and Tool Protocol Support
The technical viability of an AI gateway depends on its specialized runtime features: how it optimizes token costs, secures tool access, and enforces organizational policies.
The table below contrasts how the leading alternatives implement governance primitives, response acceleration, and protocol orchestration.
| Gateway Solution | Semantic Caching Engine | MCP Gateway Support | Token Budgeting Hierarchy | Guardrails & Data Redaction | Native SDK Drop-in Replacement |
|---|---|---|---|---|---|
| Bifrost | Built-in (Vector store integrations) | Native (Client, Server, Code Mode) | 4-tier (Key, User, Team, Customer) | Built-in Secrets, PII, AWS/Azure integration | Yes (OpenAI, Anthropic, Bedrock, etc.) |
| LiteLLM | Optional Redis / Qdrant plugin | Basic proxy routing | 2-tier (Key, Team) | Basic Python regex filters | Yes (OpenAI format) |
| Cloudflare AI Gateway | Exact match / Edge cache | No native MCP | Basic request rate limits | Cloudflare WAF integration | Yes (Prefix URL) |
| Envoy AI Gateway | External service filter | Emerging community specs | Basic rate limiting | External WebAssembly filters | Yes (OpenAI format) |
| Apache APISIX | External Redis cache plugin | No native MCP | Key-based request quotas | Basic regex / Lua plugins | No (Manual config) |
| Zuplo | External cache service | Basic HTTP tool routing | Custom TypeScript policies | Custom middleware | Yes (Custom route) |
| Gloo Gateway | Redis integration | No native MCP | Kubernetes-level quotas | Envoy filter extensions | Yes (Envoy route) |
| OpenRouter | Internal provider cache | No native MCP | Account credit limits | Provider-dependent | Yes (OpenAI format) |
Semantic Caching vs Exact-Match Caching
Traditional gateways like Kong cache responses using exact string hashing (MD5 or SHA-256 hashes of the HTTP request body). In LLM applications, exact-match caching rarely exceeds single-digit hit rates because minor prompt changes, differing whitespace, or conversational preambles invalidate identical hashes.
In contrast, Bifrost incorporates semantic caching directly into the routing pipeline. By generating vector embeddings of incoming prompts and indexing them against a local or remote vector store, the gateway identifies semantically equivalent questions (such as "How do I reset my password?" versus "What is the procedure to change a forgotten password?") and returns cached completions in approximately 5 milliseconds. This technique reduces downstream provider token expenditures by 20% to 60% on routine workloads without degrading response quality.
Model Context Protocol (MCP) Tool Orchestration
As autonomous agents transition from basic conversational interfaces to multi-step tool execution, the gateway must govern interactions between models and tools. The Model Context Protocol, open-sourced by Anthropic, establishes an open standard for tool discovery and execution.
Kong requires its enterprise-gated AI MCP Proxy plugin to map REST APIs into MCP tools. However, routing agentic traffic through standard proxies introduces "context bloat": when an agent connects to multiple MCP servers, the full schema of every tool must be injected into the prompt context window on every turn, consuming tens of thousands of tokens before execution begins.
Using Bifrost as an MCP gateway addresses this challenge natively. Bifrost supports an optimized Code Mode execution pattern where models write concise Python orchestration code rather than issuing sequential JSON tool declarations. The gateway executes this code securely against aggregated MCP servers, reducing round-trip network hops, preserving token budgets, and preventing sensitive internal tool schemas from leaking into untrusted prompts.
Extending Governance Beyond the Ingress: The Endpoint AI Challenge
Deploying a centralized AI gateway secures server-side microservices, backend agent pipelines, and web applications that are explicitly configured to point at the gateway URL. However, this addresses only half of an enterprise's AI footprint.
In modern engineering organizations, substantial generative AI usage occurs directly on employee laptops and workstations. Software developers run terminal agents like Claude Code, Codex CLI, and Gemini CLI; utilize IDE extensions like Cursor; and interact with browser-based models like ChatGPT and Claude. When developers configure these local tools with personal API keys or direct provider endpoints, that traffic bypasses the centralized gateway entirely, creating unmonitored "shadow AI."
Beyond routing, Bifrost applies governance and security controls (virtual keys, budgets, guardrails, audit logs) centrally, and Bifrost Edge extends that same governance and security to AI traffic on employee machines, with endpoint enforcement on each device.

Bifrost Edge runs as a native system agent across macOS, Windows, and Linux, distributed fleet-wide through Mobile Device Management (MDM) platforms such as Jamf, Microsoft Intune, and Kandji. Once deployed, Edge transparently intercepts AI traffic from supported desktop applications and coding tools, applying the exact same app governance, virtual keys, and content guardrails configured at the central gateway without requiring developers to manually edit local configuration files. Furthermore, Edge provides visibility into local MCP server governance, identifying and restricting unvetted tool integrations across the entire device fleet.
Frequently Asked Questions
What makes an AI gateway different from a traditional API gateway like Kong?
An AI gateway is purpose-built for non-deterministic, long-lived streaming connections and token-based accounting. Traditional gateways like Kong count HTTP requests and inspect static status codes, while AI gateways calculate costs based on prompt, completion, and reasoning tokens, manage provider failovers, cache responses semantically using vector similarity, and orchestrate Model Context Protocol tools.
Can Kong Gateway run AI workloads without enterprise plugins?
Kong Gateway offers an open-source ai-proxy plugin that provides basic multi-provider routing and request transformation. However, advanced capabilities required for production architectures, including token-aware rate limiting, semantic caching, enterprise MCP tool governance, and comprehensive guardrails, are gated behind Kong Konnect or Kong Enterprise licensing tiers.
How does Bifrost achieve 11 microseconds of overhead?
Bifrost is written in Go and optimized for minimal memory allocation and lock contention in high-concurrency environments. Unlike Kong, which executes Lua scripts inside an NGINX worker process, Bifrost compiles down to a native binary with an efficient internal request pipeline, achieving sustained 11-microsecond overhead at 5,000 requests per second in published benchmarks.
What is the Model Context Protocol (MCP) and why should a gateway support it?
The Model Context Protocol (MCP) is an open standard that allows AI models to discover, read, and execute external tools and data sources. An AI gateway acting as an MCP gateway centralizes tool connections, enforces role-based tool filtering, injects authentication headers dynamically, and prevents models from wasting prompt context on unused tool definitions.
How does semantic caching lower generative AI infrastructure costs?
Semantic caching converts incoming prompts into vector embeddings and queries a vector database for conceptual similarity rather than exact string matches. When an incoming prompt matches an existing cached query within a defined cosine similarity threshold, the gateway returns the cached response in milliseconds, eliminating downstream API fees and model latency.
How does Bifrost address shadow AI on developer machines?
While server gateways only capture traffic explicitly directed to their network endpoints, Bifrost pairs with Bifrost Edge (currently in alpha). Bifrost Edge is an endpoint agent deployed via MDM across employee workstations that routes traffic from tools like Claude Code, Cursor, and desktop LLM clients through the centralized gateway, enforcing organization-wide budgets, virtual keys, and security guardrails automatically.
Recommendation and Next Steps
For organizations seeking a direct alternative to Kong AI Gateway, the optimal choice depends on infrastructure maturity and workload requirements:
- For production enterprise workloads requiring the lowest latency, comprehensive governance, and native MCP support: Bifrost is the clear top choice.
