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
GitHub Copilot
GitHub Copilot is an AI coding assistant that spans completion, chat, agent mode, automated code review, and a cloud agent that opens pull requests, working across VS Code, Visual Studio, JetBrains, Xcode, Neovim, Eclipse, the CLI, and github.com.
- Widest editor and surface coverage of any AI coding assistant
- Repository, issue, and pull request context needs no extra setup
- Mature governance — audit logs, access and budget controls, IP indemnity
- Switchable models rather than a single fixed one
- Inline completion has been overtaken by dedicated AI editors
- Agent output on large or unusual codebases still needs close review
- Governance features are spread across six tiers, so tier choice is fiddly
