| 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. |
