Codeium

Free AI code completion that works in 40+ editors — the same company behind Windsurf IDE

Visit Website Free for individuals

Codeium is the best free AI autocomplete you can add to your existing editor. It works in basically everything — VS Code, JetBrains, Vim, Emacs, you name it. The completions are good, and you are not hitting a paywall after a trial period.

The catch is that Codeium the extension is now the “free tier” of Windsurf the company. The more advanced features — agent mode, multi-file editing, deep project context — have moved to the Windsurf IDE. If you just want solid autocomplete in your current editor without paying anything, Codeium is the answer. If you want more, they want you to switch to Windsurf.

What's good

  • Actually free for individual developers — not a trial, not freemium
  • Works in 40+ IDEs including VS Code, JetBrains, Vim, and Emacs
  • Supports 70+ programming languages

Watch out for

  • Advanced features (agent mode, deep context) moved to Windsurf IDE
  • Autocomplete quality is solid but a step behind Cursor and Copilot
  • The company's focus has shifted to Windsurf — Codeium extensions get less attention
