bryel

OpenTelemetry-native observability for LLM apps and agents — ship traces from any framework to bryel.

Drop in the SDK and every model call, tool call, token count, and cost lands in bryel as OpenInference traces. From there, attach feedback to any generation, turn real runs into datasets, and explore it all — including from a coding agent over the remote MCP.

Start here

Quickstart

Send your first trace in a few minutes.

SDKs

TypeScript, Python, Browser, or the HTTP API.

Concepts

Traces, intents, feedback, and datasets.

Coding agents

Connect a coding agent over the remote MCP.

What you get

Any framework via OTel

An OTLP exporter and span processor at the core. Use the Vercel AI SDK adapter, an OpenInference instrumentor, or your own OpenTelemetry spans.

Traces to intents to feedback

Capture full agent runs, then attach 👍/👎, scores, and corrections to any generation.

Datasets from production

Turn real traces and feedback into datasets you can curate and reuse.

Remote MCP for coding agents

Give coding agents direct access to your traces through a remote MCP server.
