After three months of using Cursor, GitHub Copilot, and Codeium on real production projects, the differences are clear. Cursor is the overall winner for complex projects. Its ability to index your entire codebase locally means it rarely suggests code that conflicts with existing patterns. The Composer mode — where you describe a feature in natural language and it modifies multiple files coherently — is genuinely transformative. GitHub Copilot excels at inline completions and has the best IDE integration, especially for JetBrains users. Its new PR review feature is impressive. Codeium is the dark horse: completely free, surprisingly capable, and now supports over 70 languages including obscure ones like Fortran and COBOL. For a solo developer on a budget, Codeium is hard to beat. Our recommendation: use Cursor Pro if you work on complex multi-file projects, Copilot Pro if you're deep in the GitHub ecosystem, and Codeium if you want zero cost. All three are dramatically better than writing code without AI assistance — the productivity gap is now too large to ignore.
