Codeium
Formerly a free AI autocomplete plugin — the technology now lives inside Windsurf (rebranded Devin Desktop after Cognition's 2025 acquisition) rather than as a standalone product.

Overview
Codeium is a free AI coding toolkit that competes directly with GitHub Copilot on features while undercutting it on price, which is free for individual developers, permanently. Its autocomplete covers 70+ programming languages, integrates with over 40 IDEs including VS Code, JetBrains, Vim, and Neovim, and provides a chat assistant for explaining code, generating tests, and debugging. The free tier is not a stripped-down trial; it includes unlimited autocomplete suggestions and full chat access without a usage cap.
Codeium Enterprise adds single-tenant deployment, SAML/SSO, and the ability to run on self-hosted infrastructure, important for organizations with compliance requirements around where code is sent. In benchmark comparisons, Codeium's autocomplete accuracy sits close to Copilot's for common language patterns, with the gap most visible on complex, project-specific context where Copilot's larger training set shows. For budget-conscious developers, students, and teams where per-seat licensing is a meaningful cost, Codeium is the clearest value play in the AI coding assistant market.
