Hey munkay- we're free for unlimited users. Principally, we believe teams shouldn’t have to be limited by user counts when deciding which project management system to use. Most are still clunky and cap at 10 users for free accounts- planning to have a free forever plan for unlimited users (much like Gitlab).

Paid plans may include functionality for enterprise teams, full fledged integrations and/or smart features such as automated sprint management.

As for Github auth- that's coming!
