It offers a free tier, with Pro from around $20/month. The best value is GitHub Copilot, whose in-editor completions and chat accelerate SPA development for as little as $10/month, with a free tier for many users.
This list is for front-end developers and product teams building client-rendered apps with React, Vue, Svelte, or Angular. The 2027 field spans AI editors (Cursor, Windsurf), in-editor assistants (Copilot, Tabnine), full-app generators (Bolt.new, Lovable, v0), and frameworks with AI-friendly tooling (Vite).
