Aider vs Devin, side by side
Field	Aider	Devin
Tier	B	A
Why this tier	It is mature and transparent, with git-aware clean commits. It is less autonomous than newer agents, which is why it sits at B-tier.	It is good for assign-and-forget tickets because it works on its own, in the cloud or on your machine, and tests in its own browser. You get less hands-on control than with terminal agents, which keeps it below the S-tier agents.
Best for	Clean, git-aware commits People who want a mature, transparent terminal pair programmer	Assign-and-forget tickets Teams happy to let an agent work on its own
Skip if	You want a highly autonomous agent You don't work in the terminal	You want hands-on control of every step You'd rather drive an agent from your own terminal
