Mythex vs Bolt

Bolt is built for the fastest possible spike in a browser. Mythex is built for the spike to become something you keep.

The short answer

Choose Bolt when the goal is a throwaway prototype in the next ten minutes. Choose Mythex when the thing you build has to stay up, hold data, and still make sense in three months.

Pick Mythex when

The project will outlive the prototype
You need a real database and a URL you can hand to customers
You want one credit balance covering both building and hosting
You want to continue the build from Claude, Codex or Cursor

Pick Bolt when

Absolute speed to a first preview is the whole requirement
You may well discard the project after the demo
You want their breadth of frontend frameworks more than a managed host

Questions

Is Mythex faster than Bolt?

Not to the first preview — Bolt runs in the browser and that is hard to beat. Mythex starts a real cloud sandbox, which costs a few seconds and buys you a terminal, a database, persistent hosting and a project that is still there next month.

Can I keep a Bolt prototype going in Mythex?

Describe what you built and Mythex will build it in a project with a database and a public URL. There is no direct import today.
