Codeium

Free AI-powered code acceleration toolkit — autocomplete, search, and chat.

Codeium is a free, AI-powered code acceleration platform that provides fast autocomplete, intelligent code search, and AI-powered chat across 70+ programming languages and 40+ IDEs. Unlike many AI coding tools, Codeium offers its core autocomplete and chat features for free to individual developers indefinitely, powered by proprietary models optimized for low latency. The autocomplete engine delivers multi-line suggestions with sub-150ms latency, while Codeium Chat provides contextual code generation, explanation, and refactoring assistance. The tool also includes an AI-powered natural language code search that helps developers find functions, patterns, and logic across their codebase by describing what they want in plain English. With enterprise options for on-premises or private cloud deployment and SOC 2 Type II compliance, Codeium serves both individual developers and security-conscious organizations at scale.
