About StackBlitz
Bolt.new is an AI-powered web development platform operated by StackBlitz, launched in October 2024. It allows users to create, edit, run, and deploy full-stack web applications directly in the browser using natural language instructions, without requiring a local development environment. The product is built on StackBlitz's WebContainers technology, which runs Node.js natively in the browser.
The platform supports popular frameworks including React, Next.js, Astro, and Vite, and integrates with deployment services such as Netlify. Users can prompt the system to scaffold entire applications, modify code, install npm packages, and interact with a live preview — all within a single browser tab. Bolt.new targets developers, designers, and non-technical users who want to prototype or ship web projects quickly.
StackBlitz, the parent company behind Bolt.new, was founded in 2017 by Eric Simons and Albert Pai and is headquartered in Austin, Texas. StackBlitz had previously raised funding from investors including Google Ventures. Bolt.new gained significant traction shortly after launch, reportedly reaching millions of users within weeks and generating substantial revenue run-rate, though specific figures have not been officially disclosed.
