Someone sends a link
A Den invite looks like vulpio.app/join/7FQ2-KM9P. It names the Den, not a server farm.
Community chat
Vulpio is a friendlier place to gather — Dens with rooms, one-link invites, and conversations the service cannot read. No homeserver. No third-party client hunt.
Windows, Android, or the web · version 0.1.0 · macOS, Linux, and iOS are on the way
Saturday is chapters 4–6. Bring one sentence you actually want to talk about.
Same rooms as desktop. The service cannot read them.
Display name here is still Harbor. Handle stays harbor#1842.
How it works
If you already know how to live in servers and rooms, you already know Vulpio. The difference is the container: every room belongs to a Den you can recognize, invite people into, and moderate.
You never pick infrastructure. One official app. One invite. Then you are in the room with your people.
A Den invite looks like vulpio.app/join/7FQ2-KM9P. It names the Den, not a server farm.
Windows, Android, or the web. There is no client list and no homeserver picker.
Text, voice, members, and roles live in one place. New members decrypt messages sent after they join.
Built for circles
Dens on the left, rooms in the middle, conversation in front of you, members on the right. If you have used Discord, you already know where to look — without the stadium energy or the shop.
Book circles, neighborhood groups, choirs, civic crews, classrooms, and small shops. Vulpio is community chat first. Games can visit. They do not own the room.
Messages, attachments, and calls are end-to-end encrypted on member devices. The service has no routine technical path to decrypt them.
Talk on the porch, see each other, or share a page. Media is encrypted end to end above the call transport.
Owner, Administrator, Moderator, Member. Kick, ban, lock rooms, and review reports without a plugin store.
Private conversations start with a request. Blocking is mutual. Safety numbers are there if you want to compare them.
Replies, reactions, calendars, and on-device search over the messages this device can already decrypt.
Administrators can add a Den-owned bot as a visible encrypted participant, with scoped, revocable credentials.
The latch
Your messages, attachments, and calls are end-to-end encrypted. Vulpio’s service has no routine technical path to decrypt your content. Participants can still disclose content through reports, recordings, screenshots, or integrations they choose.
Ordinary room text, attachments, direct messages, and call media. The server stores ciphertext, not the keys to read it.
Accounts, membership, room structure, delivery timing, and that a call happened. We publish that limit instead of pretending it is not there.
The room stays closed.
