Bolt.new by StackBlitz generates full-stack web apps from a prompt and runs them in the browser via WebContainers – no local setup, no waiting on environments. It installs npm packages, provisions databases, and ships with hosting so a working app is live minutes after the first prompt.
The free tier grants 1M tokens per month (300K daily cap), which is enough to evaluate the workflow honestly. Pro at $25 per month raises the ceiling to 10M tokens with rollover, adds custom domains and removes Bolt branding; Teams at $30 per member centralize billing and access controls.
