Codeium
✓ Editorially verifiedFree, fast AI autocomplete + chat across 70+ editors.
Pick Codeium if you want serious AI autocomplete for free, especially in Neovim or other less-mainstream editors.
Skip it when you need the deepest multi-file agent workflow or enterprise compliance reporting.
Codeium is a free autocomplete and chat product for developers with the broadest IDE coverage of any AI coding tool — JetBrains, VS Code, Neovim, Vim, Sublime, Emacs, and a long tail of others. Now also packaged with Windsurf, their AI-first editor that competes head-on with Cursor.
The core autocomplete is genuinely fast and good enough for the 80% case. The free tier is generous (unlike most competitors' free tiers, which are deliberately crippled), which makes Codeium the natural starter pick for an individual developer who isn't ready to pay $20/mo.
Code quality on hard tasks lags Cursor and Copilot, and the agentic features are less developed. But for autocomplete and chat — the bread and butter of daily AI-assisted coding — it's the most accessible choice.
Codeium is the best free AI coding tool, full stop. The Windsurf editor is a credible Cursor alternative for people who'd rather not pay, and the editor coverage genuinely beats every competitor.
