The 5 Free Claude Proxies We Tested (And Why We Still Built a Paid One)
When we started building ShadoClaw, the obvious question from everyone was: "Why? There are free proxies already."
Fair question. We actually tested them — five of them, seriously, over several weeks. Here's what we found, why they all fell short for production Nexus use, and what that taught us about what a real managed Claude proxy needs to be.
Why We Were Even Looking at Proxies
If you're a heavy Nexus user running Claude as your daily driver, you've probably hit this wall: Anthropic's API pricing stings. Not because the model is expensive per call — it's actually reasonable at scale. The problem is the management overhead:
- Monthly invoices that vary wildly based on usage
- A single API key shared across all your automations, agents, and sessions
- No usage caps — one runaway cron job can spike your bill $40 in a night
- Anthropic's occasional policy enforcement actions (ask anyone who lost access in April 2026)
So you look at proxies. Here's what the open-source landscape offers.
The 5 Proxies We Tested
1. LiteLLM (self-hosted)
What it is: The most mature open-source proxy for LLM APIs. Supports 100+ models, has a dashboard, rate limiting, spend tracking.
What we liked:
- Genuinely comprehensive — it can route to OpenAI, Anthropic, Gemini, local models, all through one endpoint
- Active development, good docs
- Virtual keys with per-key budgets
What broke down:
- Setup is a project, not a 10-minute task. Docker Compose, Redis for rate limiting, Postgres for logging — you're standing up infrastructure
- For Nexus specifically, it's overkill. You don't need 100 models. You need Claude to work reliably.
- The dashboard is powerful but complex. We spent more time configuring LiteLLM than using Claude.
- Self-hosted = you own uptime. When it goes down (and it does), your OpenClaw agents go silent.
Verdict: Great for teams with a DevOps person who wants multi-model routing. Wrong tool if you just want Claude to work.
2. OpenAI-Compatible Reverse Proxy (various GitHub projects)
What it is: A category of lightweight proxies that accept OpenAI-format API calls and translate them to Anthropic calls. Usually <500 lines of code.
What we liked:
- Dead simple to deploy — often just
node index.jsor a single Docker container - No database, no Redis, minimal dependencies
- Works with any client that supports OpenAI format (which Nexus does)
What broke down:
- No persistence. Restart the container, lose your request logs.
- No rate limiting. One aggressive agent floods your key.
- Most projects are abandoned after 3-6 months. The one we liked most had its last commit 14 months ago.
- Security is an afterthought — several exposed the underlying API key in logs
Verdict: Fine for personal experiments. Not for anything you depend on.
3. Cloudflare AI Gateway
What it is: Cloudflare's managed caching and observability layer for AI APIs. Not a proxy in the traditional sense — more of a pass-through with logging.
What we liked:
- Zero infrastructure to manage
- Good observability — you can see every request, cost, latency
- Caching can save real money if you make repetitive calls
- Cloudflare's reliability is basically bulletproof
What broke down:
- You still use your own Anthropic API key and account. The billing problem does not go away.
- No actual access management — it's a single key pass-through
- If Anthropic suspends your account, Cloudflare AI Gateway does not help at all
- Caching is great for static workloads, useless for conversational AI (which is most OpenClaw use)
Verdict: Good complementary tool. Does not solve the core problem.
4. LocalAI (self-hosted)
What it is: Local inference server for open-source models. Sometimes used as a Claude proxy via shims.
What we liked:
- Completely free at inference time once set up
- Privacy — your prompts never leave your machine
What broke down:
- The models available locally are not Claude. This sounds obvious, but it's the thing people forget.
- Claude Sonnet 4 on your local machine... does not exist. The best local alternatives are meaningfully worse for reasoning-heavy tasks.
- Hardware requirements are steep for anything decent. 24GB+ VRAM for good results.
- Latency on local hardware is 5-10x slower than Anthropic's API
Verdict: Interesting for specific use cases (privacy-sensitive, offline). Not a Claude proxy. It's a different model.
5. Free Tier API Wrappers
What it is: Services that offer "free Claude API access" through unofficial means. Usually gray-market API key sharing or reselling.
What broke down:
- Your prompts route through unknown third-party servers
- Most are violating Anthropic's ToS (key sharing)
- Response quality varies because you're often getting rate-limited or downgraded model calls
- These services disappear overnight. We saw two shut down during our testing period.
- No SLA, no support, no continuity
Verdict: Do not use these for anything you care about.
What We Learned: The Gap
After testing all five, we had a clear picture of what was missing.
The problem is not the proxy. It's the relationship with Anthropic's billing.
Every open-source solution still requires you to hold an Anthropic API key. That means you're exposed to Anthropic's account policies, your billing is unpredictable, you're responsible for your own key security, and when something breaks at the API level, you're debugging it at midnight.
What OpenClaw power users actually need is someone who manages that relationship for them. Predictable monthly cost, managed access, no surprise invoices, no account risk.
That's what we built.
How ShadoClaw Is Different
ShadoClaw is a managed Claude API proxy. We handle the Anthropic relationship; you get a clean endpoint that works with Nexus out of the box.
Predictable billing. $29/month for Solo, $79/month for Pro (5 accounts), $179/month for Team (20 accounts). No per-token surprise invoices. No bill shock when your cron job ran hot for three days.
No Anthropic account required. You do not need an API key. You do not need an Anthropic account. We absorb that complexity.
Your key is yours. Your ShadoClaw key routes to Claude. It's isolated from other users. We do not share keys.
Uptime is our problem. When LiteLLM goes down on your server at 3am, that's your 3am. When our infrastructure has an issue, it's our 3am.
Nexus-native setup. Point your Nexus config at the ShadoClaw endpoint, add your key, done. No Docker, no Redis, no YAML configs.
The Honest Comparison
Here is how the options stack up for production OpenClaw use:
LiteLLM self-hosted: Hours of setup, infrastructure to maintain, your Anthropic account required, unpredictable cost. Good for DevOps teams that need multi-model routing.
Free proxies (GitHub): Minutes to set up, but abandoned projects, no rate limiting, security gaps. Fine for experiments.
Cloudflare AI Gateway: Zero infrastructure, great observability, but your Anthropic account and billing are still your problem.
Local models: Full privacy, free inference, but you are not running Claude. Different model, different quality.
ShadoClaw: Minutes to set up, no infrastructure, no Anthropic account needed, flat monthly pricing, production-ready.
Who Should Use What
Use LiteLLM if you are a DevOps-comfortable team that needs multi-model routing and has someone to maintain infrastructure.
Use Cloudflare AI Gateway if you want observability on top of your existing Anthropic setup.
Use local models if you have specific privacy requirements and can accept lower model quality.
Use ShadoClaw if you are a Nexus power user, developer, or agency founder who wants Claude to just work reliably, predictably, without infrastructure overhead.
