Pros & Cons

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

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
