Bolt.new

Bolt is a browser-based AI app and website builder that lets you create websites, apps, and prototypes by describing what you want in plain language. It targets product managers, entrepreneurs, marketers, agencies, and students who need to move from idea to working product without writing code manually or stitching together separate tools.

The core workflow is conversational. You describe what you want to build, and Bolt generates the code, tests it, refactors it, and iterates automatically. The platform claims a 98% reduction in errors compared to typical AI coding workflows, handling the debugging loop that usually slows people down.

Design system support is one of its more practical features. You can import your team's existing component library, whether that's Material UI, Chakra UI, Shadcn, or a custom system like the Porsche or Washington Post design systems, and Bolt builds within those constraints. That makes it more useful for teams with established brand guidelines than generic AI code generators.

It's also built for scale. Bolt handles large, complex projects with improved context management, so the AI doesn't lose track of your codebase as it grows. That's a real problem with most AI coding tools, and it's worth noting Bolt addresses it directly.

On the infrastructure side, Bolt Cloud includes hosting with custom domains and analytics, unlimited databases, user management and authentication, and SEO optimization. These come bundled rather than requiring separate accounts or third-party services. One interface, from first prompt to live production product.

Bolt integrates frontier coding models from multiple AI labs inside one interface. Unlike alternatives such as Replit or Dyad, you're not locked into a single model or forced to switch between platforms as the underlying AI shifts. If you need more control over your development environment, tools like Daytona handle that side of things separately.
