Frequently Asked Questions
01 What's the best completely free AI coding tool?
Codeium offers the most generous free tier with truly unlimited code completions and chat for individual developers. Unlike GitHub Copilot Free (capped at 2,000 completions/month) or Sourcegraph Cody Free (200 chat messages/month), Codeium has no meaningful usage limits for personal use. It supports 70+ programming languages across 40+ IDEs.
02 Are free AI coding tools good enough for professional use?
Yes, for many developers. Codeium's free tier offers unlimited completions comparable to paid tools. GitHub Copilot Free's 2,000 completions per month is sufficient for most casual coding sessions. However, power users doing 8+ hours of daily coding may hit limits on GitHub Copilot Free or Sourcegraph Cody Free and should consider paid plans starting at $9-10/month.
03 When should you upgrade from a free AI coding tool?
Upgrade when you hit monthly limits (e.g., GitHub Copilot's 2,000 completions or Sourcegraph Cody's 200 chat messages), need access to frontier models like GPT-4o or Claude 3.5 Sonnet, require team features like admin controls and audit logs, or want advanced capabilities like multi-file editing in Cursor. Paid plans start at $9/month for Sourcegraph Cody Pro and go up to $20/month for Cursor Pro.
