Subscription
The Mac app is free. A subscription adds remote control from this browser and the phone app, with the first month free.
Cancelling, receipts, and card changes live in the billing portal. Access runs to the end of the period you have paid for. See what it includes →
How access works
Two checks, one account
Signing in proves who you are. Pairing grants this browser permission to view or control one Mac. Both devices must be signed into the same Marginal Utility account.
The Mac owns the full device list and permissions. Manage them in Saggar under Settings → Remote control, or read the remote control guide. Account details and access tokens remain on Kiln.
