What is Codeium?
Codeium is the scrappy underdog taking on GitHub Copilot with a legitimately impressive free tier. Unlike most "freemium" tools that hobble their free versions, Codeium gives you unlimited autocomplete and AI chat without payment - a move that's shaking up the AI coding space.
What sets it apart is breadth over depth. Supporting 70+ programming languages (compared to Copilot's focus on popular ones), Codeium works across virtually any development environment. Their "intent validation" attempts to catch bugs before they happen, and training on GitHub issues means it understands real-world coding problems, not just syntax.
Fresh off a $150M funding round in February 2025, they're clearly betting big on disrupting the paid AI coding market. The new Windsurf IDE shows they're not just building extensions - they want to own the entire coding experience.
