Give Claude Code, Codex, and Cursor a self-improving shared memory

Beacon is an open-source memory layer for AI coding agents that captures session history across Claude Code, Cursor, Codex, OpenCode, and over 20 other tools. The captured data includes workflows, corrections, and debugging patterns, which are then made reusable by future agents. This eliminates the need for each agent to learn the same information from scratch.

Beacon is designed for developers who want agent knowledge to compound across tools rather than being lost when a session ends. The software is open source and operates locally first, with an option to sign in through beacon.sh. Signing in does not forward any data; confirming the Beacon Cloud option will install Beacon and start forwarding the data.

The local beacon MCP server, which can be accessed without the network, stores the data locally. Beacon also provides a dashboard for users to explore and understand the session history.
