Open-source memory for coding agents, synced over SSH

deja is a zero-dependency Go binary that indexes your Claude Code, Codex, and opencode conversation histories into a fast local search layer , no models, no cloud, nothing leaves your machine. It supports MCP-based agent recall, auto-injects relevant memory at session start, redacts credentials at index time, and searches gigabytes of logs in under 10ms. Retroactive indexing means months of past sessions are instantly searchable.
