Bolt.new

Bolt.new is StackBlitz's in-browser AI full-stack app builder. From a natural language prompt it generates, edits, runs, and deploys complete web applications inside the user's browser tab using StackBlitz's WebContainer runtime — a WebAssembly-based Node.js operating system that boots a real filesystem, npm/pnpm/yarn package manager, terminal, and live preview without a remote VM. The product targets product managers, entrepreneurs, marketers, agencies, and non-engineer builders with conversational app creation, design-system import from Figma and component libraries (Material UI, Chakra UI, Shadcn/ui), built-in database and authentication, one-click deploy to Netlify or bolt.host, custom domains, GitHub version control, and integrations with Supabase, Stripe, Expo, and MCP servers. Bolt.new itself is a hosted, UI-driven product metered in monthly AI tokens with Free, Pro, Teams, and Enterprise tiers — there is no public REST/HTTP developer API or CLI. StackBlitz separately ships the WebContainer API as a JavaScript/TypeScript SDK (npm @webcontainer/api) for embedding the same in-browser dev environment in third-party sites, plus a StackBlitz SDK (@stackblitz/sdk) for programmatically opening projects. The Bolt.new reference codebase is open source under MIT at github.com/stackblitz/bolt.new as a foundation for building custom AI dev agents; the hosted commercial product is closed source.

Bolt.new is profiled on the APIs.io network. Tagged areas include Artificial Intelligence, AI App Builder, No-Code, Low-Code, and Full-Stack.

Bolt.new’s developer surface includes documentation, pricing, signup flow, YouTube channel, engineering blog, and 22 more developer resources.

scored 2026-09-25 · rubric v0.23.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/bolt-new: open an issue to ask a question, or submit a pull request to add artifacts.
