Bolt.new
StackBlitz AI — scaffold, edit, and preview entire web apps in the browser from a chat prompt.
About Bolt.new
Bolt.new, built by StackBlitz, is an AI web app builder that runs entirely in your browser: describe an app, and it writes, runs, and previews the code live — no local setup, no waiting for builds. It is the closest thing to having a senior developer pair-programming with you inside a browser tab.
What makes Bolt different is its execution model: instead of generating code you must copy and run yourself, it actually runs the app in a WebContainers environment in your browser, so you see the result instantly. You can then chat with it to fix bugs, add features, and tweak the design, watching each change take effect live.
It supports React, Vue, and other modern frameworks, works with package installs, and can connect to external services. For prototyping, learning web development, or building small-to-medium apps fast, Bolt.new is a favorite among developers and non-developers alike.

Bolt.new: strengths and trade-offs
Our own read on the product — written from the vendor’s documentation and our use of it, not from a vendor brief.
What it does well
- Runs the development environment in the browser, so you see the app working while it is being generated.
- Supports several popular frameworks and gives you clean, exportable code.
- Very fast from prompt to a working prototype.
Where it falls short
- Token costs for longer sessions can spike sharply.
- Complex state management and multi-page apps quickly exceed what prompting can hold together.
- No integrated backend or hosting, unlike the fuller platforms.
Who should skip Bolt.new
- Production applications that need to be maintained long term.
- Anything requiring authentication, payments or real backend logic out of the box.

How this listing was checked
- Source. Pricing, plan names and feature details come from the vendor’s own product and pricing pages — for this tool, Bolt.new official site. This listing was last edited September 12, 2026.
- Prices change. AI pricing and free tiers move faster than almost any other software category. Treat the figure here as a starting point and confirm it at the source before you buy — we re-check listings on a rolling schedule but cannot promise a page is current on the day you read it.
- Independence. No vendor paid for this page or for its position, and no vendor reviews it before publication. See our review methodology and advertising disclosure.
- Corrections. Found something wrong or out of date? Tell us — verified errors are corrected and dated.
