What is the best AI coding tool for building web apps?
Top contenders and their strengths
Cursor is an AI-first code editor (forked from VS Code) that excels at multi-file edits, codebase-wide understanding, and chat-driven development. It's popular among developers who want deep AI integration without leaving their editor.
GitHub Copilot is a mature AI pair programmer that integrates into VS Code, JetBrains, and Neovim. It's great for autocomplete, inline suggestions, and quick fixes, but less powerful for large-scale refactoring than Cursor.
Replit is a browser-based IDE with built-in AI (Ghostwriter) that lets you code, run, and deploy from any device. It's ideal for beginners, quick prototypes, and collaborative coding, though it may feel limited for complex, large-scale apps.
- Cursor: best for AI-native editing and multi-file changes
- GitHub Copilot: best for inline autocomplete in existing IDEs
- Replit: best for beginners and browser-based development
- Windsurf (formerly Codeium): a rising alternative with strong free tier
How to choose
If you already use VS Code and want AI that feels like a supercharged autocomplete, start with GitHub Copilot. If you want AI to help you refactor entire files or projects, try Cursor. If you want zero setup and easy sharing, Replit is a strong pick.
Consider pricing: Copilot has a free tier for individuals and paid plans around $10–$20/month. Cursor offers a free tier and paid plans starting around $20/month. Replit has a free tier and paid plans starting around $7–$20/month. Prices vary by region and change over time, so check current rates.
What about free options?
Codeium (now Windsurf) offers a generous free tier for individuals. Continue.dev is an open-source extension that lets you connect your own API keys. Some tools like Tabnine have free basic plans.
For web apps specifically, you might also consider v0 by Vercel for UI generation or Bolt.new for full-stack prototypes. These are more specialized but can be very fast for certain tasks.
Common mistakes
- Assuming the most expensive tool is always the best for your needs.
- Overlooking free or open-source alternatives that may be sufficient for small projects.
- Choosing a tool based on hype without testing it on your actual workflow.
