Overview

Overview

Bolt.new provides an in‑browser development environment where AI models can not only generate code but also control the filesystem, package manager, terminal, and server. Powered by StackBlitz’s WebContainers, it supports installing npm packages, running Node.js servers, and interacting with third‑party APIs—all without any local setup.

Who it's for

Designed for developers, product managers, and designers who need rapid prototyping, Bolt.new lets you scaffold frameworks like Vite, Next.js, Astro, or Tailwind, iterate through chat‑driven prompts, and deploy to production with a single command. Projects can be shared instantly via a URL, making collaboration and feedback loops seamless.

Deployment

When you’re ready, the AI can trigger a deployment step directly from the chat interface, publishing the app to a live URL. The platform operates in beta, with a free tier and optional paid plans for higher AI token limits or private projects.
