v0
v0 turns natural-language prompts into shadcn-style React components and full pages you can iterate in chat, then export to your Next.js repo—built for design-minded developers who want fast UI scaffolding with production-friendly defaults.
Bolt
Bolt targets rapid UI shells, marketing sites, and mobile prototypes with hosting and GitHub sync—use it when speed matters more than bespoke backend complexity.
GitHub Copilot
Copilot meets developers where PRs and issues already live—inline suggestions, workspace-aware chat, and agent flows that can touch multiple files inside VS Code or JetBrains.
Replit Agent
Describe a product, iterate in the design canvas, and let Replit Agent scaffold code, dependencies, and deploys—popular with students and indie hackers validating ideas in hours.
Cursor
Cursor blends fast autocomplete, multi-file agent runs, and @-style codebase references so you rarely leave the editor to understand or refactor large trees.
Windsurf
Windsurf emphasizes long sessions, cascade-style edits, and context that follows you across files—aimed at teams that want an agentic pair programmer without constant re-prompting.
