Bolt

What it is

Bolt (bolt.new) is an AI app builder from StackBlitz. You describe an app in chat, an agent writes the code, and a live preview runs next to the conversation. Bolt's help center says it focuses on JavaScript: Node.js on the backend and any JavaScript framework on the frontend. Mobile apps go through an Expo integration.
