Bolt.new is an AI-powered, browser-based platform that lets people build and deploy full-stack web applications by chatting with an AI rather than writing code by hand. Built by StackBlitz, the company behind the in-browser "Instant Dev Environments" and WebContainers technology, Bolt.new turns a natural-language description of an app into working code, then runs, tests, and iterates on that code directly inside the browser — no local setup, environment installation, or dedicated IDE required.
Company and Technology
Bolt.new is StackBlitz's flagship consumer product. StackBlitz, Inc. is known for pioneering WebContainers, described on its site as "the first WebAssembly-based micro operating system," which boots a full Node.js development environment inside the browser in milliseconds. This is the underlying engine that lets Bolt.new install packages, run servers, and preview a working app without any backend infrastructure on the user's machine. StackBlitz says its tools are used by frontend and product teams at companies including Google, Meta, Shopify, Salesforce, Intel, Mozilla, Cloudflare, and Stripe.
Core Features
Bolt.new generates apps from a chat prompt and automatically routes each request to what it considers the most suitable AI model for the task. It includes built-in testing and iteration loops intended to reduce the number of errors that make it into generated code, and it supports large projects with expanded context handling compared to earlier versions of the tool.
Beyond code generation, Bolt.new ships with "Bolt Cloud," a built-in full-stack layer offering unlimited databases, authentication and user management, hosting with analytics, SEO optimization, and support for custom domains — so a project can go from prompt to a live, publicly reachable app without leaving Bolt.new. Projects can also be started by importing an existing design from Figma or a codebase from GitHub, and Bolt.new supports popular design systems such as Material UI, Chakra UI, Shadcn UI, the Porsche Design System, and the Washington Post Design System, plus the ability to import a company's own brand guidelines.
Pricing
Bolt.new uses a token-based subscription model. The Free plan costs $0 and includes a 300,000-token daily limit (1,000,000 tokens monthly), 10MB file uploads, website hosting, up to 333,000 web requests, and unlimited databases. The Pro plan costs $25 per month, removes the daily token cap, starts at 10 million tokens per month with rollover, and adds custom domains, private site sharing without Bolt branding, 100MB uploads, up to 1 million web requests, SEO boosting, and AI image editing. Teams costs $30 per member per month and layers centralized billing, admin controls, and organization-wide sharing on top of the Pro feature set. Enterprise is quote-based and adds SSO, audit logs, a dedicated account manager, and 24/7 priority support. Users on higher Pro tiers or annual plans can buy additional, non-expiring token reloads.
Who It's For
Bolt.new positions itself for people who want to move from idea to working, deployed software quickly without deep coding knowledge — product managers, entrepreneurs, marketers, agencies, and students or hobbyist builders — as well as developers who want to prototype full-stack apps rapidly inside the browser rather than setting up a local toolchain.
