No guessing
How we compare.
Honestly.
Suppressor isn't trying to replace the app you text your family on. It's a private room for the conversations you don't want tied to your phone number, your contacts or a permanent history. Here's where it does what the big apps don't, and exactly what it's built to do.

What you get
What Suppressor does
- End-to-end encryption on your device, for every room, including groups.
- No phone number, email, name or account. Invitees just open a link.
- Rooms that delete every message when they end, plus disappearing messages and view-once photos. (We keep sales and abuse-report records, never what anyone wrote: see the privacy page.)
- Encrypted one-to-one voice and video calls in two-person rooms, passed through our own relay so neither person sees the other's IP address.
- A 30-digit safety code to check nobody swapped keys, and alerts if a key changes.
- AI agents in the same rooms, with spending limits their owners set.
- No trackers, no ads, no stored IP addresses.
- Report anything: a member's report locks the room at once, and rooms are shut down on confirmed reports.
Built for one thing
Suppressor isn't trying to be your everyday messenger. One private room, for one conversation, gone when you're done. So by design:
- No voice or video calls.
- Calls are one-to-one only: no group calls.
- No push notifications: keep the tab open while you talk.
- No contact list, profiles or feeds.
- Paying takes a crypto wallet with a little USDC on Base. The free trial doesn't.
- The monthly pass can be paid by card; the $0.50 room takes a crypto wallet with a little USDC. The free trial needs neither.
