What it is

Bolt.new is an AI web development agent you use in your browser. You describe an app in a chat, and the AI builds it, runs it, and can deploy it, without installing anything locally. The README says it runs in an in-browser environment built on StackBlitz's WebContainers, so the AI can install npm packages, run Node.js servers, and edit files.

  • Describe a web app in a prompt and have the AI scaffold and run it
  • Install npm libraries such as Vite or Next.js inside the browser environment and run a Node.js server
  • Share a running project through a URL
  • Deploy a project to production from the chat interface

Great for

  • People who want to prototype a full-stack web app quickly without local setup
  • Developers who want to see AI-generated code run in a live browser environment
  • Non-coders such as PMs or designers who want a working web prototype, per the README's own framing
  • Developers who want to study or build on the open-source Bolt codebase

Not ideal for

  • People who need to work offline or fully on their own machine, since the README says it runs in the browser
  • Teams that need predictable AI costs, because the README describes daily token limits and paid tiers for more tokens
  • Anyone expecting a stable production product, since the README states Bolt.new is in beta

How to get it

  1. 1

    Use it in the browser (or self-host)

    Clone the open-source codebase (only if you want to build your own tool)

    git clone https://github.com/stackblitz/bolt.new
  2. 2

    Run it

    • Open https://bolt.new in your browser
    • Describe the app you want in the chat, naming any frameworks you prefer
    • Use the enhance icon to refine your prompt before sending if you like
    • Run and edit the generated project in the browser
  3. 3

    Get the most out of it

    • Name the frameworks or libraries you want (such as Astro, Tailwind, or ShadCN) in your first prompt so Bolt scaffolds with them
    • Use the enhance prompt icon to refine your request before submitting
    • Scaffold the basic structure first, then add features in later messages
    • Batch simple changes into one message to save time and reduce API credit use, as the README suggests

Strengths

  • No local setup is required, according to the README
  • The AI can control the filesystem, package manager, terminal, and browser console, not only generate code
  • The core codebase is open source under the MIT license

Trade-offs

  • The README says Bolt.new is in beta
  • Free use is limited by a daily token limit, after which AI interactions pause until the next day or an upgrade
  • The README gives no detail on how well generated apps perform or on which deployment targets are supported
