ZUsers is a developer platform by ZZZTECH. It gives your product sign-up, sign-in, roles, permissions and subscription billing in one place, and you plug it in through a REST API. Events can be received in real time via webhooks, and an admin dashboard for users, roles and paid plans is included.
There is a Free plan with no time limit. Paid plans are billed monthly; upgrades take effect immediately and downgrades take effect at the start of the next period.
