Paid plans are coming
We're not offering paid plans just yet. Higher tiers — with more apps, higher usage limits, and priority support — will arrive as soon as we finalize a payment solution that works for our customers.
In the meantime, the Basic plan is free and fully functional. Have a custom requirement or want to be notified when paid plans launch?
