StackBlitz's browser-based AI development environment. Prompt, run, edit, and deploy full-stack apps in a single browser tab — powered by WebContainers (Node.js in the browser) and Claude. Bolt V2 added Bolt Cloud with native hosting, Postgres, auth, and analytics.
+ Pros
- Full Node.js dev stack runs entirely in the browser via WebContainers — no local setup
- Bolt Cloud provides native hosting, Postgres, auth, storage, and edge functions
- Open source (stackblitz/bolt.new) with a self-hostable bolt.diy variant
- 5 million+ users — one of the fastest-growing AI dev tools ever
- Supports React, Next.js, Svelte, Vue, and mobile via Expo
− Cons
- Token-based pricing with rollover can be hard to predict for heavy users
- Complex backend logic or monorepo projects can exceed browser sandbox limits
- Primarily Claude-powered — multi-model support is secondary
- Less suitable for existing large codebases — best for greenfield projects

Bolt.new is StackBlitz's browser-based AI development environment, launched in October 2024 and growing to more than five million users in its first year. Unlike code-only AI tools, Bolt runs an entire Node.js stack inside the browser using StackBlitz's WebContainers — the AI agent has full control over the filesystem, package manager, dev server, and terminal, so it can install dependencies, run servers, and hit live URLs without leaving the tab.
Bolt V2 (October 2025) added Bolt Cloud: native hosting, databases, authentication, file storage, edge functions, and analytics — closing the deployment gap that earlier versions left to Netlify or Vercel. Powered primarily by Claude with multi-model support, Bolt produces React, Next.js, Svelte, and Vue applications, plus mobile via Expo. The platform is open source: stackblitz/bolt.new on GitHub, plus bolt.diy for self-hosting against your own LLM providers.

Signature Snippet
Open bolt.new and type: "Build a SaaS landing page with a pricing table, newsletter signup, and animated hero, then add a /dashboard with magic-link auth and a Postgres table of signups." Bolt scaffolds the Next.js app, provisions Bolt Cloud auth and DB, runs the dev server, shows a live preview, and one-click deploys to a custom domain.More in this Space
