Pros & Cons

Greptile

  • Industry-leading 82% raw bug catch rate reflects genuinely strong review accuracy
  • Claude Agent SDK-powered autonomous investigation goes beyond simple pattern matching
  • Free Developer tier available for testing before committing to Pro
  • March 2026 shift to $1-per-review pricing beyond 50 reviews diverges from the flat-rate norm most competitors maintain
  • High-volume teams could see unpredictable cost scaling compared to flat-fee competitors
  • The pricing change sparked real community backlash, worth factoring into long-term vendor trust considerations

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
