Why it matters
- The only fully free (unlimited) AI code completion across 70+ languages — zero monthly cost for individual developers.
- 40+ IDE integrations make it the most portable AI coding tool — works everywhere from VS Code to Vim to Eclipse.
- Codeium's models are trained specifically on code and updated regularly without the GPT-4 licensing restrictions.
- Parent company Exafunction also makes Windsurf IDE, giving access to a more integrated AI coding experience on the same ecosystem.
Key capabilities
- Inline code completion: Context-aware single-line and multi-line code completions as you type.
- Codeium Chat: Chat interface for explaining code, generating functions, and answering coding questions.
- Codebase search (Command): Semantic search across your entire codebase to find relevant code or functions.
- 70+ language support: JavaScript, TypeScript, Python, Go, Java, C++, Rust, PHP, Ruby, Swift, and dozens more.
- 40+ IDE support: VS Code, JetBrains (IntelliJ, PyCharm, WebStorm, etc.), Neovim, Vim, Emacs, Sublime Text, Eclipse.
- Explanation and refactoring: Highlight code and ask Codeium to explain, refactor, or add documentation.
- Teams collaboration: Shared workspace settings and centralized billing on Teams plan.
Technical notes
- Free tier: Unlimited completions and chat for individual users; no per-month generation limits
- Teams: $12/user/month — adds team management, analytics, and priority support
- Enterprise: Custom pricing — on-premise deployment, SSO (SAML), audit logs, custom fine-tuning
- IDE plugins: Available from codeium.com or directly from VS Code Marketplace and JetBrains Marketplace
- Data privacy: Code context sent to Codeium cloud (standard); on-premise option for Enterprise
- Founded: 2021 by Varun Mohan and Douglas Chen; operating as Exafunction Inc.
Ideal for
- Individual developers and students who want AI code completion but can't justify GitHub Copilot's $10/mo cost.
- Polyglot developers working across many languages who need consistent AI support everywhere.
- Teams evaluating AI coding tools before committing to an enterprise contract.
Not ideal for
- Organizations with strict data residency requirements on the standard cloud tier — use Enterprise self-hosted.
- Users who want a full AI-native IDE experience — consider Windsurf (by Codeium) or Cursor instead.
- Workflows requiring local/offline AI with no internet dependency — use Continue.dev with Ollama for that.
