Pros & Cons

SWE-agent

  • Genuinely actively maintained with recent development activity as of September 2026
  • Model-agnostic design works with multiple leading LLMs of choice
  • Sibling project mini-swe-agent offers a simpler, equally performant alternative from the same team
  • Project itself now recommends mini-swe-agent over SWE-agent for new projects specifically
  • Requires bringing your own LLM API access, adding a separate cost beyond the tool itself
  • Open-source, community-maintained nature means no official commercial support

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
