Bolt

Bolt is the quick way to move a concept out of a static mock and into something that actually works. Tell it what you want, drop in a Figma file or a prompt, and it spits out a working prototype you can click through. That speed is useful when you need to prove an idea to stakeholders or test flows without days of handoffs.

It bundles the bits that normally slow projects down. Bolt includes hosting, databases, auth and a payments hookup so prototypes can behave like real apps during user tests. There is a Bolt Cloud roadmap for bigger projects too, so it is clearly aiming beyond throwaway demos. That means designers can validate flows end to end without dragging engineering into every early test.

Bolt also ships handy production shortcuts designers actually care about: Figma import, ready templates, a component library, and live share links for stakeholder signoff. It supports team collaboration so multiple people can work on a prototype, and Bolt Cloud lets projects scale past the single-demo stage with built-in hosting, auth and payments. Expect to polish generated layouts and interactions before handoff, but the integration and deploy pieces reduce the usual admin hassles.
