engram

Engram is a memory layer for AI coding agents. Your agent forgets everything when a session ends; Engram stores the bug fixes, decisions and conventions it learns in a local SQLite file with full-text search, then hands them back next session. It works with Claude Code, Codex, Cursor and any other agent that speaks MCP (the plug-in standard agents use to call outside tools). MIT licensed and free.

Setup is easy: brew install gentleman-programming/tap/engram, then engram setup claude-code (or your agent). One Go binary, no Node, Python or Docker. Sharing across machines works through Git sync, or Engram Cloud, which is a server you host yourself on Docker and Postgres, not a paid service.

There's no paid tier anywhere. Solo: free, five minutes. Small teams: free with Git sync or one self-hosted Cloud box. Larger teams: free, but someone owns the server, tokens and upgrades.

The catch: memory is only as good as what the agent chooses to save, and junk memories pollute later sessions. "Personal" memories are a search filter, not a privacy wall: enroll a project for sync and they go to everyone with access. Releases land almost daily, so pin versions. claude-mem is the closest alternative.
