What Is Codeium?
Codeium is built by Exafunction. Free AI code completion and chat tool for developers.
Codeium is a free AI-powered coding assistant that combines intelligent code autocomplete with a built-in chat interface, supporting over 70 programming languages out of the box. Originally launched as a standalone IDE plugin, Codeium has since evolved through its acquisition of Exafunction and the development of the WindSurf IDE, positioning itself as a direct competitor to Cursor in the AI-native IDE space. The platform offers enterprise-grade deployment options with SOC 2 compliance, SSO integration, and the ability to self-host models for organizations with strict data governance requirements. Codeium's autocomplete engine is trained on a diverse corpus of public code and provides context-aware suggestions that adapt to your project's conventions and patterns. The chat feature allows developers to ask questions, generate boilerplate, refactor code, and debug issues without leaving their editor. While the individual tier remains completely free with no usage caps, the business plan adds team analytics, admin controls, and enhanced security features. Codeium's commitment to keeping core features free for individual developers has made it one of the most popular AI coding assistants, with integrations available for VS Code, JetBrains IDEs, Neovim, and other major editors.
