About StackBlitz

StackBlitz is the company behind Bolt.new and WebContainers technology, which enables running full Node.js environments directly in the browser. Bolt.new (launched September 2024) became the fastest-growing AI development tool, enabling anyone to build and deploy full-stack web applications from a single text prompt in a browser — no local setup required. Bolt.new reached 1M+ monthly active users by December 2024.

Company History

Founded 2017 by Eric Simons and Albert Pai, StackBlitz pioneered browser-based IDEs with WebContainers technology — a full Node.js runtime running in the browser via WebAssembly. Used by Google Angular, Svelte, and Astro for their documentation playgrounds. Bolt.new launched September 2024 using WebContainers + Claude to enable anyone to build full-stack web apps from text. It immediately went viral, reaching 1M+ monthly active users and driving an $80M Series A fundraise in 2025. Figma-to-Bolt integration added for design-to-code workflows.
