Pros & Cons

Cline

  • Genuinely open-source with no subscription cost for the tool itself
  • Works with over 30 AI model providers, including local models via Ollama
  • Step-by-step approval gives full transparency into agent actions
  • Requires managing your own API key and understanding associated usage costs
  • No built-in model — quality depends entirely on which provider you connect
  • Step-by-step approval, while transparent, is slower than a fully autonomous workflow

Aider

  • Every AI-made change is a real, revertible git commit
  • Works across multiple files in a codebase, not just single-file edits
  • Open-source and not locked to a single AI model provider
  • Requires comfort with the command line rather than a graphical IDE experience
  • No built-in chat sidebar or visual diff review the way some IDE-integrated tools offer
  • Users need to bring their own API key for the underlying AI model
