Bolt is StackBlitz's AI app builder, best known for building and running full web apps in the browser from a prompt. Flash ∞ AI is an all-in-one AI workspace: you type what you want, and Flash sends each request to the AI model that does that job best.
If you are a developer who wants to edit the code and run it in the browser as you go, Bolt is a strong choice.
Flash is free to start, with credits every month and no card needed, so you can compare with your own work.
