Bender vs Bolt
Bender vs Bolt: full-stack web app or shippable mobile UI?
Bolt is a full-stack web app builder — it spins up a working project in the browser. Bender is narrower and deeper on one thing: mobile app design. If you need a polished, testable set of mobile screens rather than a running web backend, Bender is the sharper tool.

Common questions
Should I use Bender or Bolt?
Use Bolt when you want a running full-stack web app. Use Bender when you want a polished, testable set of mobile app screens you can refine with words and export as clean code.
Does Bender build a backend like Bolt?
