Chat that belongs
to you.
Eris is a new kind of chat platform — host your community on our cloud or your own server, with every message encrypted end-to-end. No company sits between you and the people you talk to.
Everything you need to build a thriving community
Private by design, powerful by default. Here's what makes Eris different.
Your Community, Your Rules
Host on Eris Cloud for instant setup and discoverability, or self-host for full control. Either way, your data belongs to you — your messages never touch a server you didn't choose.
No Passwords Needed
Forget email sign-ups and password resets. Your identity is a cryptographic keypair that you own. Move between devices by scanning a QR code — it's that simple.
Encrypted by Default
Every DM and channel message is encrypted end-to-end before it leaves your device. Not even the server hosting your community can read what you're saying.
Connected Across Servers
Even though each community is independent, they're all connected. Message friends across different servers, see who's online everywhere, and discover new communities to join.
Extend With Add-ons
Customize your community with add-ons that run safely in a sandbox. Bots, integrations, custom features — with fine-grained permission controls so you stay in charge.
Crystal-Clear Calls
Jump into voice or video calls right from any channel. Built on modern WebRTC infrastructure for low-latency, high-quality conversations — no third-party apps required.
Privacy isn't a feature.
It's the foundation.
Every layer of Eris is built with encryption at its core. Your messages are scrambled before they ever leave your device, and only the people you're talking to can unscramble them. Not us, not the server admin, not anyone.

Communication should be a right, not a product
Today's chat platforms treat your conversations as inventory. They mine your messages for data, lock you into their ecosystem, and make decisions about your community without you. We think that's broken.
Eris is built on a simple idea: the people in a conversation should be the only ones who can read it, and the community running a server should be the only ones who control it. No ads, no algorithmic feeds, no mysterious policy changes. Just a platform that works for you, not the other way around.
Your Community, Your Rules
Host on Eris Cloud or self-host — either way, you run it exactly how you want. No platform overlords.
Community Owned
No VC-funded growth hacks. Built by people who use it, for people who use it.
Federated Future
No single company controls the network. Every server is equal.

One Device, Many Identities: Keep Your Communities Separate
You can now create multiple identities on a single device and assign each one to a different guild. Work stays work, personal stays personal — and no one can link them.

How Eris Secures Your Data with End-to-End Encryption
End-to-end encryption sounds technical, but the idea is simple: only you and the person you're talking to can read your messages. Here's how we make that happen without sacrificing speed.
One Identity, Every Server: What Federation Actually Means
You've heard the buzzword, but what does federation mean in practice? Think of it like email — anyone can run a server, and they all talk to each other. Here's why that matters.
