Which Aider plan is actually worth it
Aider costs nothing, so your spend is whatever the model costs. Cheap models keep it to cents per session; frontier models on large repos can run several dollars a day. It suits developers comfortable in the terminal. Honest skip: if you want a GUI editor or one predictable bill, Aider is not that tool.
The limits people complain about
- - API costs scale with repo size, because Aider sends a repo map plus files as context
- - Terminal only, with no built-in GUI
- - Local models are free but noticeably weaker at multi-file edits
Aider pricing FAQ
Is Aider free?
