The honest brief

Aider

CLI-only and model-agnostic: auto-commits every AI edit as its own git commit, so changes are trivially revertable.

  • Fully open-source, BYO-key
  • Auto-commits each edit to git
  • Works with any model incl. local
  • Strong on its own Polyglot benchmark
  • No editor lock-in — pure terminal
  • No GUI — terminal comfort required
  • You pay model API costs yourself
  • Less hand-holding than IDE agents
  • Setup/config heavier than hosted tools

OpenCode

Fully open-source and provider-agnostic where most agent CLIs are vendor-locked — swap among 75+ providers, including local models.

  • Fully open source
  • Swap among many providers and local models
  • Terminal, desktop, and IDE surfaces
  • No code stored on external servers
  • Quality varies with chosen model
  • Fast-moving, frequent releases
  • Zen's curated models cost extra
