16 tools · Last checked Sep 12, 2026

How to choose

  1. Confirm support for your editor first; JetBrains, Visual Studio and Neovim coverage varies a lot between extensions.
  2. Look at which models are included and whether you can switch providers or bring your own API key.
  3. Agent features differ widely: some only autocomplete and chat, others can edit many files and run commands.
