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.

Beacon Overview

Beacon is an open-source memory layer for AI coding agents that learns from your work across Claude Code, Cursor, Codex, OpenCode, and 20+ other harnesses. It captures full session history, identifies useful workflows, corrections, and debugging patterns, and makes that knowledge reusable by future agents. Built for developers who want agent knowledge to compound across tools instead of disappearing when a session ends.

Key Capabilities:

- Cross-harness history - sessions from Claude Code, Cursor, Codex, OpenCode, Cline, and 20+ harnesses in one place
- Knowledge that compounds - workflows, corrections, debugging patterns, and repo conventions that survive beyond a single session
- Shared agent memory - reviewed knowledge future agents can retrieve through MCP or Agent Skills
- Exact session replay - prompts, responses, tools, commands, edits, approvals, MCP activity, and tokens in one trace
- Local-first portability - durable JSONL, explicit destinations, and no harness lock-in

🚀 Quick Start

Beacon is open source and local-first. Interactive endpoint setup signs in through
beacon.sh and preselects Beacon Cloud, with an explicit Local opt-out. Signing in
