Free AI code completion and chat for 70+ languages with enterprise on-premise deployment
Codeium is a free AI coding assistant supporting 70+ programming languages with inline code completion, natural language search, and an AI chat interface. Its enterprise tier offers on-premise deployment on the organisation's own infrastructure — keeping proprietary code entirely off external servers. Codeium's free individual tier with no usage caps has made it the largest free AI coding tool by user count.
Codeium is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Codeium's fundamental proposition is unusual in the AI tools market: the individual tier is free with no usage caps, no credit system, no 'free tier until you hit the limit.' Every completion, every chat message, every search query runs free for individual users indefinitely. This model, funded by enterprise deployments, has attracted millions of individual developers who want professional-quality AI assistance without a subscription.
Codeium's free tier includes inline code completion, AI chat, natural language code search, and refactoring suggestions across all 70+ supported languages — with no monthly limits. GitHub Copilot's free tier caps at 2,000 completions per month; Codeium's does not cap. For active developers who hit free-tier limits quickly, this distinction is significant.
Codeium's enterprise on-premise deployment runs the AI model on the organisation's own servers — no code leaves the network. For financial institutions, healthcare providers, defence contractors, and government agencies with strict data handling requirements, this deployment model enables AI-assisted coding within compliance constraints that cloud-only tools cannot satisfy. The enterprise model is also available as a VPC deployment in the customer's own cloud account.
Codeium's 70+ language support extends into territories other tools avoid: Fortran for scientific computing, COBOL for legacy enterprise systems, Solidity for smart contracts, and Julia for numerical computing all receive meaningful completion support. For teams maintaining codebases in languages that Copilot underserves, Codeium's breadth is a practical differentiator.
