Codeium
Free AI code completion and chat tool for individuals, with enterprise-grade privacy. Works across 70+ IDEs with fast, accurate suggestions.
Overview
Codeium is an AI code assistant that has carved out a strong position as the leading free alternative to GitHub Copilot. It offers unlimited autocomplete suggestions for individual developers at no cost — a proposition that has attracted over a million users since launch. The tool supports more than 70 programming languages and works across virtually every popular IDE, from VS Code and JetBrains to Neovim, Emacs, and even Eclipse.
Where Codeium differentiates itself most clearly is on privacy and enterprise readiness. The company trains its models exclusively on permissively-licensed open-source code, which reduces intellectual property concerns for organizations. Enterprise deployments get self-hosted options with zero data retention, SOC 2 Type II compliance, and fine-grained admin controls — features that have led large companies to adopt it over Copilot.
The chat and command features let you ask questions about your codebase, generate boilerplate, and refactor functions inline. Completion quality is solid and noticeably fast, though power users doing complex multi-file reasoning may find Cursor or Copilot's latest models produce more contextually aware suggestions.
