Free (Pro: $15/month)

Free

8, 7, 10, 8, 7, 8, Top marks on value — genuinely free for what matters (autocomplete) and fast. Deducted points for chat quotas, weaker multi-file capabilities, and product transition uncertainty.

Unlimited Autocomplete — real-time code completion, multi-line suggestions, no cap on free tier
Codeium Chat — AI chat assistant inside your editor for questions, refactors, explanations
Codeium Search — natural-language semantic search across your entire codebase
70+ Languages — Python, JavaScript, TypeScript, Go, Rust, C++, Java, Ruby, PHP, Swift, Kotlin, more
IDE Integrations — VS Code, JetBrains, Vim, Neovim, Visual Studio, JupyterLab
Windsurf Integration — Codeium powers AI features in StackBlitzs Windsurf AI-native editor

Genuinely free for individuals — no usage cap on autocomplete
Fast, responsive autocomplete that competes with paid alternatives
Codeium Search is genuinely useful for navigating unfamiliar codebases
70+ programming languages — broader than Copilot initial free offering
IDE integrations across VS Code, JetBrains, Vim, Neovim, and more
Backed by StackBlitz — well-resourced and actively maintained post-acquisition

Chat has usage quotas on the free tier — runs out faster than you expect
Not as capable as Cursor or Copilot for complex multi-file refactoring
Context awareness degrades on very large codebases
Pro plan at $15/month approaches Copilot at $10/month — value weakens at paid tier
Part of a product in transition (Codeium to Windsurf) — feature overlap creates confusion

Windsurf — StackBlitz full AI IDE built on Codeium infrastructure
GitHub Copilot — $10/month, deeper VS Code integration, more mature context awareness
Cursor — Strongest AI-native editor, generous free tier, $20/month Pro
Tabnine — Another free-option coding AI with strong enterprise and local deployment features
