Records every Claude Code session to local SQLite, then surfaces them through nine MCP tools plus a web dashboard and terminal UI. The hooks layer writes tool calls and checkpoints passively. The server exposes `replay_resume` to generate structured briefs from dead sessions, `replay_search` for full-text queries across your history, `replay_insights` for per-session metrics like death cause and error rate, and `replay_diff` to compare two runs side by side. Also ships `replay_export` to render sessions as standalone HTML traces. Runs on port 8766 alongside Claude Bridge. Think of it as observability over your entire session history, where native `--resume` and `/rewind` handle only the active session. Install once via `claude-replay install` and it records everything going forward.
