Bolt.new by StackBlitz (bolt.new) Review
Bolt.new by StackBlitz (bolt.new) is an AI-powered fullstack development sandbox that runs entirely inside your web browser. It transforms natural language prompts into working fullstack applications with live servers.
Powered by StackBlitz WebContainers, Bolt.new executes a real Node.js runtime and npm package manager inside browser WebAssembly. The AI plans file structures, writes code, installs packages, and fixes runtime errors without remote server dependencies.
Developers test live interactive previews in real time with sub-100ms hot reloading. Finished applications deploy directly to GitHub, Netlify, or Supabase with a single click.
In-depth review: what Bolt.new by StackBlitz (bolt.new) actually does
Checked 28 Oct 2026Bolt.new (bolt.new) is a browser-based AI app builder from StackBlitz. You describe a website, web app, or mobile app in chat, and Bolt writes and runs the code in a browser-based development environment. It builds full-stack JavaScript apps, can add a database, and publishes to a live URL.
Bolt runs on WebContainers, the browser technology StackBlitz created to run Node.js without a local install. The product is aimed at founders, product managers, marketers, agencies, and developers who want a working prototype quickly. Bolt also supports mobile apps through an Expo integration.
Features worth knowing
Bolt runs in Chrome, Edge, and other Chromium-based browsers, and in Safari with some limits. Projects open in the browser without a local toolchain.
Every project can use a built-in database, authentication, file storage, and hosting on a bolt.host subdomain. Paid users can connect a custom domain.
Bolt offers Standard and Max agents. Standard is the fast, token-efficient default; Max is built for large codebases and complex changes and requires a paid plan.
You can start from a GitHub repository, a Figma frame, a Google Stitch design, or a Lovable project. GitHub sync keeps commits in both places.
What does Bolt.new cost?
Free costs $0 and includes 1 million tokens per month, with a daily cap of 300,000 tokens. Pro costs $25 per month and includes 10 million tokens, token rollover, a custom domain, and access to the newest models. Teams costs $30 per member per month and starts at 10 million tokens per member. Enterprise is a custom annual contract billed by consumption.
Hosting follows the same split. Free includes up to 10 GB of bandwidth and 333,333 requests per month. Pro includes 30 GB and 1 million requests, with pay-as-you-go overage up to a spending cap you set. Paid hosting is included with every paid subscription.
How do Bolt tokens work?
Tokens are pieces of text that Bolt reads and generates. Most usage comes from reading, understanding, and syncing project files, so larger projects cost more per message. Free tokens reset on the first of each month; paid tokens reset on the renewal date.
Unused paid tokens roll over and stay valid for two months. Free tokens do not roll over, and purchased reload tokens do not expire. Bolt says only the highest monthly Pro plan or an annual Pro plan can buy reloads.
Free users also have a daily cap of 300,000 tokens. Hitting it does not block direct edits in Code view, which do not use tokens. Further prompts wait for the next daily reset or an upgrade.
What can you build with Bolt?
Bolt builds websites, web apps, and mobile apps. Web projects use JavaScript frameworks with Node.js on the backend; mobile apps use the Expo integration. You can add a database, user sign-in, file storage, and server functions inside Bolt Cloud.
Projects can be imported from GitHub, Figma, Google Stitch, or Lovable. You can edit code directly in Code view, run terminal commands, and publish to a bolt.host address or a custom domain. Projects can also connect to services such as Supabase, Stripe, and MCP servers. Bolt says the code you create is yours to use for commercial projects.
Does Bolt.new work in the browser?
Yes. Bolt runs on WebContainers, so Node.js and npm packages run in the browser tab. On desktop it supports Chrome and other Chromium-based browsers. Safari works with differences: the terminal is unavailable, and previews are hosted rather than local.
Bolt works on mobile browsers, but Code view is desktop-only. Browser extensions such as ad blockers, privacy tools, or VPNs can interfere with the editor, so Bolt suggests turning them off if something breaks.
Limitations to weigh first
- –The Free plan is capped at 1 million tokens per month and 300,000 tokens per day, and free tokens do not roll over.
- –Free hosting is limited to 10 GB of bandwidth and 333,333 requests per month. It also adds a Made in Bolt badge and does not support custom domains.
- –Safari lacks the terminal and uses hosted previews, Code view is desktop-only, and custom domains require a paid plan.
Common questions
Is Bolt.new free?
Yes, there is a free plan with 1 million tokens per month and a 300,000-token daily cap. It includes hosting on a bolt.host subdomain and adds a Made in Bolt badge to published sites.
What happens when Bolt tokens run out?
Free users wait for the daily or monthly reset, while paid users can upgrade or buy reload tokens if their plan allows it. Direct edits in Code view do not consume tokens.
Can Bolt build a full-stack app?
Yes. Bolt builds full-stack JavaScript apps with Node.js on the backend and can add a Bolt Cloud database, authentication, file storage, and server functions.
Does Bolt.new work in Safari?
Yes, with differences. Safari does not have the terminal and uses hosted previews, so Bolt recommends Chrome or another Chromium-based browser for the full experience.
