Codeium is a free AI-powered code completion and chat tool that integrates into over 40 IDEs and supports 70+ programming languages to provide intelligent code suggestions and assistance. Its enterprise product Windsurf combines an agentic coding environment with deep codebase understanding, enabling multi-file edits and complex refactoring workflows. Unlike GitHub Copilot, Codeium offers a genuinely free tier with unlimited completions, making professional-grade AI coding assistance accessible to individual developers and students who cannot justify enterprise pricing.
