Aider
Aider is an open-source AI pair programming tool that runs in your terminal, builds a map of your whole repository for context, works with almost any LLM including local models, and commits each change to git with a written message so every edit can be diffed and undone.
- AI changes become ordinary git history — diffable, revertible and cherry-pickable with tools you already trust
- Per-commit granularity means you can keep the good changes and discard the bad ones separately
- The repo map degrades gracefully in large codebases where context-window approaches fail
- Model-agnostic, so a provider's bad quarter does not become your problem
- Terminal-only, which is a real barrier for developers who work primarily in a GUI
- Cannot see your selection, cursor, failing tests or language server errors the way an IDE agent can
- Bring-your-own-key billing has no floor and no ceiling, so spend is invisible until you check
Tabby
Tabby is an open-source, self-hosted AI coding assistant offering code completion, chat and an agent feature, built so teams can run AI coding on their own infrastructure for security, transparency and control rather than sending code to a cloud service.
- Code never leaves your network
- Open source brings transparency and adaptability
- Removes a blocker for regulated teams
- Avoids per-seat cloud lock-in
- Self-hosting adds operational work
- Public page is thin on detail
- May trail frontier cloud models in polish
