Bolt.new
StackBlitz's in-browser AI development agent. Writes, runs and deploys full-stack apps from a prompt using WebContainers, with no local setup at all.
About Bolt.new
Bolt.new is the AI builder that actually runs your app while it writes it. Because StackBlitz's WebContainers put a full Node.js environment inside the browser tab, the agent can install dependencies, boot a dev server, read the real error output and fix itself — no local setup at all. Bolt sits between prompt-to-app builders and real code editors.
What is Bolt.new?
Bolt.new is StackBlitz's AI full-stack development agent. You describe an application, and Bolt scaffolds it, installs packages, runs it, shows you the live preview and iterates on your feedback — then deploys it. The defining technical choice is WebContainers, StackBlitz's browser-based runtime, which means everything happens client-side in a real Node environment rather than in a sandboxed simulation. In the 2026 vibe-coding landscape that positions Bolt in the middle: Lovable is the credit-metered app generator for founders who have never opened a terminal, Replit is a full development environment with an agent attached, and Bolt runs entire dev environments inside your browser tab.
Key Features
- WebContainers runtime: A genuine Node.js environment in the browser — npm installs, dev servers, terminals, all client-side.
- Self-correcting agent: Reads real runtime and build errors and fixes them rather than guessing.
- Full-stack scaffolding: Frontend, API routes, database wiring and auth from a single prompt.
- One-click deployment: Ship to Netlify and other hosts straight from the editor.
- Editable code: Unlike pure no-code tools, the generated project is real code you can read, edit and export.
Who Should Use Bolt.new?
Bolt is best for founders, designers and developers who want a working full-stack prototype in an afternoon without configuring anything locally. It is also a good teaching tool, because the generated code is real and inspectable. It is less suited to large existing codebases — it shines on greenfield projects — and heavy users should watch token consumption, which is the main cost driver. Developers who want to work in an existing repo should use Cursor, Windsurf or Copilot instead.
Pricing
Bolt bills by tokens. The free plan includes 1 million tokens per month, enough for small experiments. Pro is $25/month with 10 million tokens, and higher individual tiers run at $50, $100 and $200/month for correspondingly larger allowances. Teams is $30 per user per month. Token top-ups are available when you exhaust a monthly allowance mid-project, which in practice happens on any reasonably complex app.
Pros and Cons
| Pros | Cons |
|---|---|
| Real dev environment in the browser, zero setup | Token allowances run out quickly on complex apps |
| Agent fixes itself using actual runtime errors | Browser runtime limits some native tooling |
| Deploy in one click, export real code | Not designed for large or legacy codebases |
| More control than pure prompt-to-app tools | Free tier only covers small experiments |
Bottom Line
Bolt.new remains the best way to go from an idea to a running, deployed full-stack app without opening a terminal, and the WebContainers approach gives it a self-correction loop that prompt-only builders cannot match. Budget for tokens — that is the real cost — and treat it as a prototyping and MVP tool rather than a home for a long-lived production codebase.
