Bolt.new

What is Bolt.new?

Bolt.new is a browser-based AI development environment for building web applications, websites, and prototypes, created by StackBlitz. It enables users to create full-stack projects by chatting with AI coding agents directly in the browser, eliminating the need for local development setup or multiple tools.

The platform integrates frontier AI coding models that handle code generation, testing, refactoring, and iteration automatically. Users can import design systems from Figma or GitHub—including Material UI, Chakra UI, Shadcn UI, and custom enterprise systems like Porsche Design System and Washington Post Design System—to maintain brand consistency and build production-ready applications on-brand. The environment claims to reduce coding errors by 98% through automated testing and context management that scales to handle projects 1,000 times larger than comparable tools. Bolt Cloud provides enterprise-grade backend infrastructure built directly into the platform, including hosting, databases, user authentication, custom domains, and SEO optimization, eliminating the need for separate hosting or backend services.

The freemium model allows free project creation and building, with paid tiers offering additional features and resources. The tool supports multiple user workflows: product managers can prototype ideas in hours, entrepreneurs can launch businesses in days, marketers can build campaign pages with SEO optimization, agencies can deliver more projects without scaling headcount, and students can learn by building functional applications. Integrations with Figma and GitHub enable seamless design-to-code workflows and version control. The platform operates entirely in the browser, removing installation barriers and allowing immediate project launch.

Bolt.new competes directly with similar AI development environments like Vercel v0, GitHub Copilot, and Cursor. It distinguishes itself through integrated backend infrastructure and design system import cap
