Questions & answers.

What happens if I stop paying?

Paid features deactivate. The MIT core keeps working exactly as before — your projects and configuration are never affected.

Is the core really free for commercial use?

Yes. Loopbox Core is MIT licensed. Use it in any project, personal or commercial, with no restrictions.

How do seats work?

Each seat is for one named user. Add seats mid-cycle and the cost is prorated for the remaining billing period.

Can I try paid features first?

A 14-day trial is available on request. Contact niklas@niklasschmidt.dev.
