Deploy full-stack web environments in browser using WebContainers. Perfect for prototyping instantly.
Bolt.new is a browser-based tool that builds web applications from a text prompt. You describe an app, and it generates the code, runs it in an in-browser development environment and shows a live preview, with no local setup needed. It is useful for founders, designers and developers who want to prototype an idea quickly or scaffold a project to continue elsewhere. It has a free tier, with paid plans that increase usage allowances. A common limitation is that results get harder to steer as a project grows, and generated code often needs cleanup before it is ready for real users.
