Description

Aider is the open-source AI pair programmer that works in your terminal with your existing codebase. It edits files and commits to git automatically, supports 100+ LLMs, and consistently tops AI coding benchmarks — the choice of developers who want full control.

Windsurf by Codeium is the agentic IDE that keeps developers in flow. Its Cascade agent can plan, implement, debug, and iterate on multi-file changes autonomously — going beyond autocomplete to actually understand your entire codebase and take action.
