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
Codeium
Codeium was a free AI code completion tool that became Windsurf, was acquired by Cognition, and now ships as Devin Desktop. The Codeium brand is retired — this page explains the chain and what existing users should do.
- The original free individual tier was genuinely generous for its time
- Plugin coverage reached editors most AI vendors ignored
- Development continued rather than shutting down — the product still ships
- Redirects are in place, so old links still reach the current product
- The Codeium brand is retired, so its documentation is effectively orphaned
- Two renames in two years make search results contradictory and unreliable
- Terms that attracted original users may not have survived the ownership change
