Bolt.new from StackBlitz generates runnable full-stack prototypes inside StackBlitz without local Node installs. It is aimed at frontend devs and hackathon builders, with a freemium with subscriptions for private projects and higher AI generation limits. Complex backends and non-JS stacks are harder than polished marketing suggests. Editorial teams should verify fit against their compliance and workflow needs before rolling it out broadly.
