deja

Zero-dependency local memory layer that recalls what your coding agents already solved.

Desktopfreeglobal

deja is a zero-dependency local memory layer that indexes coding-agent session histories written to disk and serves relevant past work to agents over MCP at session start. It helps developers using Claude Code, Codex, and similar agents avoid re-debugging previously solved issues by searching large local histories quickly without LLMs or embeddings, syncing across machines via SSH and redacting API keys during indexing.
