Bolt.new

Bolt.new is StackBlitz's AI app builder: you describe a website or app in chat and it writes, runs and iterates on the code in the browser, routing each task to a suitable model. Bolt Cloud adds hosting with custom domains and analytics, databases, authentication and SEO tooling, so a prototype can become a live product in the same place. Bolt tests and refactors its own output as it goes, and its context management is built to keep large projects running.
