At Auvra AI, we build sophisticated automation systems for trading bots, content generation, and AI reasoning. Like many developers, we initially used platforms like n8n—but we quickly hit limitations that forced us to rethink workflow orchestration from the ground up.
That’s why my teammate Emmanuel Akanji and I created FlowSpec, a next-generation workflow language designed specifically for AI and high-performance automation.
Here’s why it’s fundamentally better than JSON-based systems like n8n’s.
The Problem with JSON-Based Workflows
Platforms like n8n rely on JSON to define workflows. While this works for simple tasks, we encountered three critical limitations when building advanced AI pipelines:
1. Spaghetti Connections
JSON forces you to define every connection manually. For example, branching a workflow to 3 destinations requires repetitive edge definitions:
"connections": {
"Node A": {
"main": [
[{"node": "Node B", "type": "main", "index": 0}],
[{"node": "Node C", "type": "main", "index": 0}],
[{"node": "Node D", "type": "main", "index": 0}]
]
}
}
This becomes unmanageable at scale.
2. No Native Support for AI Patterns
- Dynamic ports (e.g., generating inputs/outputs based on data) require hacky workarounds.
- Loops and retries must be manually implemented.
- No type safety—runtime errors from mismatched data are common.
3. Poor Performance at Scale
Parsing large JSON workflows is slow, and execution is linear by default—no built-in parallelism.
FlowSpec: A Language Built for AI Workflows
FlowSpec solves these problems with a YAML-based DSL optimized for AI/media automation.
1. Clean, Declarative Syntax
Compare n8n’s JSON to FlowSpec for the same branching logic:
n8n (JSON)
"connections": { /* 10+ lines of nested arrays */ }
FlowSpec (YAML)
connections:
branch_example:
from: node_a.output
to: [node_b.input, node_c.input, node_d.input]
- 70% less code
- Human-readable
2. Native AI/Media Features
✅ Dynamic Ports
audio_mixer:
type: multi_speaker
dynamic_inputs:
speakers:
from: script.speaker_count # Auto-create ports
port_template: speaker_{index}
✅ Built-in Loops & Retries
connections:
process_retry:
from: transcriber.output
to: validator.input
retry:
max_attempts: 3
delay: 5s
✅ Type Safety
nodes:
gpt_agent:
inputs:
prompt:
type: string
format: markdown
min_length: 50 # Validation
3. Performance Optimizations
- Parallel execution by default
- Priority controls for critical paths
- 5x faster parsing than JSON
Real-World Impact at Auvra AI
Since adopting FlowSpec:
🚀 40% faster development of new workflows
🔧 90% fewer runtime errors
📈 3x more scalable (100+ node workflows)
Example: Our trading bot’s workflow shrank from 45 lines of n8n JSON to 20 lines of FlowSpec with better error handling.
Metric | n8n (JSON) | FlowSpec (YAML) |
---|---|---|
Lines of Code | 45+ | 20 |
Branching Logic | Manual edges | Native syntax |
Execution Speed | ~500ms/node | ~100ms/node |
