ctx is an open-source Rust CLI that indexes and searches local coding-agent session transcripts and tool calls across providers like Claude Code, Codex, and Cursor. It gives agents fast, token-efficient recall of past sessions, with a paid 'ctx pro' add-on that maps code lines, commits, or PRs back to the agent session that produced them.
Use cases
- search past coding agent session history locally
- find why a line of code was written by tracing it to the agent session
- let agents recover decisions and failed approaches from earlier sessions
- reduce token spend when agents need historical context
- audit previous agent sessions in detail
- resume work across multiple agent threads
When to choose
- you use coding agents like Claude Code, Codex, or Cursor and want them to recall prior sessions
- you want fast local search over agent transcripts without sending data to the cloud
- you need to trace code changes back to the agent conversation that produced them
- you want to avoid lossy agent-memory summaries
When to avoid
- you don't use coding agents or have no local session history
- you need team-shared history across machines (attribution only works for local sessions)
- you need a hosted or web-based search interface
