Turning an idea into a working app usually means installing a development environment, choosing a framework, wiring up a database and authentication, and only then starting to build the actual feature — hours of setup before anything visible exists. Bolt.new skips straight to the visible part: describe what you want in a sentence, and it generates a real, running application in your browser, ready to keep editing or ship. Bolt.new, built by StackBlitz, is a conversational app builder that generates websites, web apps, mobile apps and prototypes entirely in the browser, with automatic AI model routing and error correction as it builds. It includes built-in databases and authentication so a generated app isn't just a static frontend, plus website hosting with custom domains and analytics, and AI-assisted image editing for visual assets. Pricing includes a free tier (300,000 tokens/day, up to 1 million/month), a Pro tier at $25/month (10 million tokens/month), a Teams tier at $30/month per member, and custom Enterprise pricing, aimed at developers, product managers, entrepreneurs, marketers, agencies and students.
