Bolt is a browser-based AI development platform created by StackBlitz that turns written prompts into working full-stack applications. You type a description of the app you want, and Bolt generates the code, spins up a complete development environment in the browser, and renders a live preview instantly. There is nothing to install and no configuration to wrestle with, since the entire stack runs on WebContainers technology that executes Node.js directly in the browser. The platform supports popular frameworks like React, Next.js, Vue, Astro, and Svelte, and it goes well beyond generating snippets. Bolt can install packages, run backend servers, connect to databases through integrations like Supabase, and deploy finished projects to Netlify with a single click. When something breaks, you can prompt the AI to fix errors, or dive into the code editor yourself and make manual changes. This mix of conversational building and hands-on editing makes it useful for both non-technical founders and experienced developers who want to skip boilerplate. Bolt has become one of the standout tools in the vibe coding movement, letting you prototype MVPs, landing pages, internal tools, and even mobile apps through its Expo integration, all in a fraction of the usual time. Pricing is token-based, with a free tier for experimentation and paid plans for heavier usage. For startups looking to build faster without hiring a full development team, Bolt is worth considering.

Features
-
AI-powered app generation
Bolt transforms natural language prompts into complete, functional applications. You describe the product you have in mind, and the AI writes the frontend, backend, and configuration code within minutes.
-
In-browser development environment
Built on StackBlitz’s WebContainers technology, Bolt runs a full Node.js environment inside the browser. There is no local setup, no dependency conflicts, and no waiting for installations to finish.
-
Live preview and instant iteration
Every change appears immediately in a live preview pane. You can test your app as it evolves, spot issues early, and requests adjustments through follow-up prompts without leaving the page.
-
One-click deployment
Finished projects can be published to Netlify with a single click. Bolt handles the build process and hosting connection, so you go from prototype to live URL, without touching deployment pipelines.
-
Framework flexibility
Bolt supports major JavaScript frameworks including React, Next.js, Vue, Svelte, and Astro. You can specify your preferred stack in the prompt, and the platform scaffolds the project accordingly.
-
Database and backend integrations
Through its Supabase integration, Bolt connects apps to authentication, storage, and Postgres databases. This means you can build genuinely functional products with real data rather than static mockups.
-
Manual code editing
Beyond AI generation, Bolt includes a full code editor. Developers can open any file, make precise changes by hand, and combine manual work with AI assistance whenever it suits them.
-
Mobile app support via Expo
Bolt partners with Expo to let you build native mobile applications from prompts. The same conversational workflow that creates web apps can produce iOS and Android projects too.

Pros and cons
Pros
- Fast prototyping: Bolt takes you from idea to working prototype faster than almost any traditional workflow
- Zero setup barrier: Because everything runs in the browser, there is no environment configuration, no version conflicts, and no installation process
- Full-stack capability: Unlike simple UI generators, Bolt handles backend logic, package installation, database connections, and deployment
Cons
- Large projects: As codebases grow, the AI can lose track of context, introduce regressions, or repeat mistakes
- Debugging still requires knowledge: When the AI gets stuck in an error loop, users without coding experience can find themselves unable to move forward
- Token costs add up: Complex projects with lots of iterations can burn through allowances
