Bolt

Bolt is an AI-powered development platform, built by StackBlitz, that lets people build websites, apps, and prototypes by describing them in natural language rather than writing code by hand. It runs entirely in the browser using StackBlitz's WebContainers technology, so a full development environment, including a file system and package manager, executes client-side without a separate local setup. The platform automatically tests and refactors generated code as part of its iteration loop, and it supports importing existing designs from Figma or code from GitHub. Bolt is aimed at a broad range of builders, including product managers, entrepreneurs, marketers, agencies, and students, who want to go from idea to a working, deployable product without deep coding expertise. Beyond generating code, it includes practical app infrastructure: databases, user authentication, SEO settings, and hosting with analytics and custom domains, so a generated project can be published rather than staying a local demo. Pricing is organized into tiers such as Standard and Pro, though specific rates are not shown on the homepage. Because it emphasizes speed and natural-language generation, teams with highly custom architecture or strict code-review requirements may still need to hand-edit generated code before shipping to production.
