Bolt.new
Full-stack apps from prompts, live in browser
The verdict
Bolt.new runs a full Node.js environment inside the browser via StackBlitz WebContainers, so generated apps actually install npm packages and serve hot-reload previews without any local machine setup. Connecting a Supabase project for a Postgres database backend or pushing a deploy to Netlify takes two clicks from inside the interface, producing a live URL in under a minute. Simple CRUD apps, dashboards, and landing pages come out clean and shippable in under 10 minutes for someone with no prior code. The free plan limits roughly 150,000 tokens per day, which exhausts quickly on any feature-rich project, and the $20 per month Pro cap is tight enough that ambitious apps will burn through the monthly allowance before the billing cycle resets.
What works
- ✓WebContainers run real Node.js in the browser so npm installs and hot reload work without a local dev environment
- ✓One-click Supabase integration adds a real Postgres database to generated apps in seconds
- ✓Supports React, Vue, Svelte, Astro, and vanilla JS with framework-appropriate scaffolding per prompt
- ✓Netlify deploy from inside the editor produces a shareable live URL in under a minute
What doesn't
- ✕Token allowance on the free plan runs out mid-session on any app with more than three or four features
- ✕Larger apps accumulate redundant components and prop-drilling patterns that need manual refactoring to clean up
- ✕No mobile output, so React Native or Flutter projects require a separate tool entirely
If Bolt.new isn't it
Alternatives worth a look
Lovable
Ship a full-stack app from one prompt
Lovable scaffolds complete React and Supabase applications from natural language prompts, handling database schema, authentication, and a deployed URL inside a single session. Each prompt iteration produces runnable code visible in a live preview, and projects export to GitHub for full ownership with no vendor lock-in. The free tier provides a limited daily message allowance that drains quickly on complex apps, pushing most active users to the $20/mo Pro plan. Code quality is production-adjacent for CRUD apps and dashboards but accumulates technical debt on larger projects because the model rewrites full files rather than making surgical edits. Developers comfortable with React can fix generated issues quickly; non-developers may hit a ceiling once the app grows beyond what iterative prompting can cleanly untangle.
Cursor
The AI-first code editor
Cursor remains the editor to beat. Its agent mode plans and executes multi-file changes with a reliability competitors still chase, and tab completion predicts intent so well it changes how you type. The fork-of-VS-Code foundation means zero relearning. At $20 a month the value question is real for hobbyists, but for anyone coding daily it pays for itself within a week. The polish is what separates it: features ship fast and rarely break.
Windsurf
Agentic IDE with a flow-state pitch
Windsurf's Cascade agent is genuinely good at keeping context across a session — it remembers what you were doing in a way that feels less transactional than rivals. The free tier is the most generous among serious AI editors, which makes it the obvious first stop for anyone testing the waters. It loses points on polish: updates occasionally wobble, and the UI carries more concept-weight (Flows, Cascades, Memories) than strictly necessary.
