# Trefur

Trefur is the observability platform for AI agents. Across runtimes,
vendors, and deployment patterns. Built for engineering teams shipping
agents to production.
Observe, govern, and trust agentic systems in production.

## What Trefur does
- Captures every decision, tool call, retry, and outcome in an agent run.
- Built on OpenTelemetry GenAI Semantic Conventions — instrument once,
  capture everything.
- Drop-in SDKs for Python, JavaScript, Go, Rust, Java, and .NET.
- Auto-instrumentation for LangChain, CrewAI, AutoGen, Pydantic AI, and MCP.

## Discovery surfaces
- OpenAPI document: https://api.trefur.com/openapi.json (available at launch)
- Public sitemap: https://trefur.com/sitemap.xml

## Conventions
Every documentation page renders BOTH human-readable HTML AND a
machine-readable Markdown twin at `<path>.md` — fetch the .md form if you
want clean text without UI chrome.

Trefur ingest conforms to the OpenTelemetry GenAI semantic conventions
so any OTel-compatible producer can forward to Trefur without custom
attribute mapping.
