Codeium

Free AI code completion — 70+ languages, many editors, free for individuals forever.

What it does

Inline completion (Tab): real-time multi-line suggestions in VS Code, JetBrains, Neovim etc.; fast and near-zero config for common languages.
In-editor AI chat (Chat): ask about code, explain errors, propose fixes with current file context; apply to code.
Super-complete / command (Cascade, in its standalone AI IDE 'Windsurf'): one sentence for multi-file changes, commands and self-checks — good for big refactors.
Repo awareness: index your project first, then suggest from whole-repo context, cross-file Q&A fits existing code.
Many languages and editors: 70+ languages, plugins for VS Code, JetBrains, Vim, Emacs, Neovim, plus a standalone AI IDE (Windsurf).

Who it's for

Coders: solo devs, students, front/back-end engineers, prototype and script makers; people wanting free AI completion without monthly Copilot / Cursor bills.

Pros & cons

Pros

Free tier gives unlimited basic completion + AI chat; near paid-tool experience for major languages, great value
70+ languages and mainstream editors; fast to plug in (VS Code plugin suggests in ~2 min)
Decent privacy stance: claims not to train on customer code; enterprise can self-host, SOC 2 Type 2 certified

Watch-outs

Cross-file understanding on complex repos is weaker than GitHub Copilot and Cursor; big projects guess wrong APIs more
Brand and Windsurf (its standalone IDE) naming is confusing
Free tier uses lighter models and may slow at peak; heavy Cascade / advanced models depend on paid
Smaller community and plugin ecosystem than Copilot; enterprise features still maturing

Pricing

Free individual tier (unlimited basic completion + AI chat; 70+ languages and mainstream editors); Pro / Teams / Enterprise paid tiers and prices follow Codeium / Windsurf's live notes.
