codeium.comAbout Codeium
Codeium (now rebranded as Windsurf for its IDE product) is an AI-powered coding assistant and development environment that offers one of the most capable free tiers in the AI coding space. Codeium's core product provides fast, context-aware code completions, an AI chat assistant, and a code search feature — all free for individual developers, with no monthly credit limits. Windsurf IDE (Codeium's standalone AI IDE, launched in late 2024) is a VS Code fork that integrates AI more deeply than extensions can, with the Cascade AI agent capable of multi-step, multi-file editing across an entire codebase, terminal access, and autonomous task execution. Codeium supports 70+ programming languages and integrates as a plugin into VS Code, JetBrains IDEs, Neovim, Emacs, and more. It has been adopted by over 1 million developers and 500+ companies.
