The Verdict
Aider is built for developers and open source contributors, with a focus on multi-file-editing and git-integration. AutoGen targets ai researchers and developers and leads with multi-agent and code-execution.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for developers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Aider has a slight overall edge — but if microsoft backed matters most to you, AutoGen may still be the right call.
