Bolt.new is StackBlitz's AI app builder for generating full-stack apps from a prompt. Free tier plus paid plans from $20/month. See features and pricing.
Bolt.new is an AI-powered app builder from StackBlitz, a company founded in 2017 by Eric Simons and Albert Pai and based in San Francisco. It launched publicly on October 4, 2024, and lets users describe an app in plain language to generate a complete, runnable full-stack web application.
The defining technical feature is that the generated app runs entirely inside the browser via StackBlitz's WebContainers technology, which executes a full Node.js runtime, package manager, and build process client-side rather than on a remote server.
Bolt.new generates frontend, backend, and dependency code from a single prompt and lets users continue refining the app through further chat instructions or direct code edits. It integrates with Supabase for backend and database needs, GitHub for version control and export, Netlify and Cloudflare for deployment, and Stripe for payments.
The platform has expanded its context handling to support significantly larger projects than at launch, and added access to newer models, including Claude models with adjustable reasoning depth, alongside the original Claude 3.5 Sonnet.
Bolt.new uses token-based pricing. The free tier includes 1 million daily tokens but no project export. Paid individual plans are Pro ($20/month, 10M tokens/month), Pro 50 ($50/month, 26M tokens), Pro 100 ($100/month), and Pro 200 ($200/month), with unused tokens rolling over for one additional month.
Teams pricing is billed per seat, with each paid member receiving a monthly token allotment based on the chosen subscription tier, enabling shared collaborative projects.
