Sblurp

Hang out in channels your community owns.

Sblurp is group chat with channels, threads and roles. Each community runs on its own server, and one Sblurp account signs you in to all of them.

Create an account Host a community

Free, in your browser. Desktop & mobile apps coming soon. Hosting your own community starts at about $4 a month.

Why another chat platform?

Tired of slow apps, warnings, ads, popups, paid-only features, AI features, strange policy decisions and all the other junk you never asked for? Sblurp is fast group chat for communities that want a place of their own, with one account that works everywhere.

Slack

Salesforce's office chat, priced per seat and getting pricier.

Free plans hide everything older than 90 days and delete it after a year.
Keep history forever, or have it delete itself after a set number of days.

No seats to buy. The server runs on a small machine you pick.
Every workspace is a new account and a new sign-in.
One account signs you in to every community.

Discord

One company holds every server, and it keeps changing the deal.

Full access now takes a face scan or a government ID.
Sign up with an email. No face scans, no ID uploads.
In 2025 a breach at a Discord support vendor exposed about 70,000 users' ID photos.
Sblurp never asks for your ID, so there is none to leak.
Watch ads to earn Orbs. Pay for Nitro to send bigger files.
No ads, no coins, no paywalled basics.
Pay for Nitro to react with an animated emoji. Really?
Animated emoji work for everyone, in messages and reactions.
One ban from Discord locks you out of every server at once.
Each community runs its own server and sets its own rules.

Matrix

Open and clever, and almost nobody can figure out how to use it.

Familiar on purpose.

Communities down the left, channels next to them, the conversation in the middle. If you have used Slack or Discord, you already know where everything is.

Two ways to run channels.

Each community picks one, and can switch later without losing a message.

Pick your channels

Like Slack. Everyone starts in a few default channels, then browses the list and joins the ones they care about.

# general412 peopleLeave
# gardening38 peopleJoin
# bread71 peopleJoin

Channels by role

Like Discord. Give someone the Film club role and the film channels show up for them. Nobody has to join anything.

# movie-nightFilm club
# new-releasesFilm clubSpoiler-safe
# lobbyeveryone

Make it yours with bots.

Paste in a few lines of JavaScript to greet newcomers, post a reminder every Monday or decide who gets in. Or bring a whole program, like an AI agent, a build server or a news feed, and it joins as a member. See how bots work.

Decide who gets in

A small script can ask a question at the door, or let in only people with a verified email or who said they are over 18.

Verified emailrequired
Over 18required

Bring your AI agent

Connect your own agent with a bot token, and it reads, answers and helps out like any member. It only sees the channels its role allows. See AI agents.

Host a community.

The server is one open-source program that keeps everything in one folder, so a small rented server or a computer at home can run it. People sign in with their Sblurp account, so your server never stores a password. A server for about 250 people online at once costs about $4 a month. Read the self-host guide.
