About Codeium
Codeium, rebranded to Windsurf for its standalone IDE product in 2024, is an AI code assistant offering completion, in-editor chat, and agentic multi-file editing. Pricing: free (unlimited completions, AI chat — the main selling point), $15/mo Pro (more model access and context window), Enterprise custom. Around 12K GitHub stars. Works as an extension for VS Code, JetBrains, Vim, Emacs, and Neovim. The free tier is the core reason to consider it — GitHub Copilot costs $10/mo for individuals, and Codeium's free tier matches it for everyday completion tasks in mainstream languages. Cascade, the agentic feature in the Windsurf IDE, enables Claude-style multi-file edits from a single chat instruction. Compared to GitHub Copilot: Codeium is free for individuals, Copilot has better cross-file context on complex repos. Compared to Cursor ($20/mo): Cursor has stronger agent capabilities and deeper IDE integration; Codeium is meaningfully cheaper. Reddit developers consistently recommend trying Codeium before paying for Copilot.
