The fastest backend for AI agents to discover
Before an LLM can use your API it has to discover it: robots.txt, sitemap, /llms.txt, the plugin manifest, OpenAPI, a health check. That handshake runs on every cold interaction — so its latency matters.
One agent, full discovery handshake
| Stack | Total (avg) |
|---|---|
| Synsema | 1.37 ms |
| Go | 1.83 ms |
| Node | 1.97 ms |
| FastAPI | 4.89 ms |
Synsema has the lowest discovery latency — ahead of Go and Node. Under a 50-agent swarm it also has the lowest per-agent latency (22 ms vs Go's 43 ms).
The part the others don't have
Matching Go and Node on speed is table stakes. The difference: Synsema is secure by default, and /llms.txt + content negotiation are built in — the same route serves HTML to humans and Markdown/JSON to agents automatically. This very post is the demo.
