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
JetBrains Junie
JetBrains Junie is a coding agent that works with any model you bring, built on the IntelliJ engine, with a Plan Mode, live prompting, human-in-the-loop control, agentic debugging in a real debugger, and a free Junie Lite layer.
- Freedom to choose and switch any model
- Strong, deliberate developer-control features
- Agentic debugging in a genuinely good debugger
- Cost control via plan-and-implement model split
- Not for those wanting a fully hands-off agent
- Best inside the JetBrains and IntelliJ ecosystem
- Bring-your-own-key means managing your own spend
