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
OpenCode
OpenCode is an open source AI coding agent built for the terminal, with desktop and IDE clients alongside. It connects to 75+ model providers, configures language servers automatically, runs parallel agent sessions, keeps conversations locally in SQLite, and is built by the team behind SST.
- MIT licensing means genuine auditability, self-hosting and no exposure to vendor pricing changes
- Local model support is the only acceptable configuration for some regulated environments
- Local SQLite storage makes retention architecturally impossible rather than merely promised
- 75+ providers means switching models is a setting rather than a workflow migration
- A tool supporting every provider is optimised for none of them specifically
- No inline diffs or visual review flow to match an editor-first tool
- Configuration flexibility is configuration work
