Beacon

An open-source, local-first memory layer that captures session history across Claude Code, Cursor, Codex, OpenCode, Cline, and 20+ other harnesses, then has Jev judge bounded, redacted trace projections for reusable lessons a person reviews.

About this project

Website · Docs · Discord · Install · Commands. Beacon captures agent session history across Claude Code, Cursor, Codex, OpenCode, and 20+ other harnesses, then turns useful workflows, corrections, and debugging patterns into reusable knowledge for future agents. A problem solved by one agent shouldn't need to be learned from scratch by another.

Highlights

  • Jev judges bounded, redacted trace projections for reusable lessons, and a person reviews them before they enter project memory or become a skill.
  • Hooks and dry runs do not call Jev; the explicit beacon memory evaluations run command is what asks it for judgments.
  • Normalizes sessions from 20+ harnesses into one OpenTelemetry-based event model, with durable JSONL and explicit destinations.
  • Local commands include beacon traces, a terminal browser for traces, timelines, token usage, and retained content, plus a local dashboard.
  • Reviewed knowledge can be retrieved by later agents over MCP or as Agent Skills, and signing in does not itself enable forwarding.

Quickstart

bash
brew trust asymptote-labs/tap
brew tap asymptote-labs/tap
brew install beacon
beacon endpoint install

Watch out

MIT-licensed. Interactive endpoint setup signs in through beacon.sh and preselects Beacon Managed with a Local opt-out; normal capture can retain sensitive session text locally, so inspect retention before enabling it.
