Chatto 0.5 Feature Preview: theme customization! You asked for it, we... maybe went a little too hard. Enjoy!

Chatto 0.5 Feature Preview: UI too hard (or maybe a little too easy?!) to read? You can now adjust UI contrast to match your age, errr, personal preference.

Chatto 0.5 Beta will be releasing next week. It's a release we deem stable enough for upgrading your own server to (but please still make backups!)

Chatto 0.5 Feature Preview: Privileged Permission Activation! If you're hanging out on a server where you have privileged permissions (editing rooms, messages, accounts, bots, ...), you now have to arm them first. Arming permissions is logged and automatically deactivates after 15 minutes.

A first experimental implementation of native 1080p60 game streaming in @chatto.run's upcoming desktop app!

Two windows, one is Chatto Desktop (it's streaming Moonring), the other is a browser window that's watching the stream

Well, it's been a fun and exciting month! The community has grown significantly, a whole bunch of people are self-hosting, experimenting with bots, building alternative clients, providing hosting templates, and I even managed to squeeze in two weeks of vacation. Now it's back to work!

We're hard at work with Chatto 0.5! If you want to learn more about what's coming, drop by Chatto HQ this Thursday for our Community Q&A. July 23, 20:00 CEST / 18:00 UTC / 2 PM ET / 11 AM PT

A Chatto message from Hendrik, our social media manager:

Chatto Community Q&A — THURSDAY (July 23) 20:00 CEST / 18:00 UTC / 2 PM ET / 11 AM PT

We're doing another one of these! Focus on the upcoming version 0.5 (no surprise release, I'm sorry!), how Chatto is doing and where it's going, and more. We're planning to go for an hour, with maybe some extended overtime if we all feel like it.

We'll use the Chatto video call feature in one of our channels here, will ping you when we're about to get started!

ICYMI, Chatto is now Open Source and available for self-hosting. It's still early days, with Chatto currently sitting at 0.4, but it's a good version that we're happily using in production, so have at it! Here's our social media manager @hmans.dev with all the deets:

Meow! Some of you have been asking for email-less signups for your email-less friends. This is currently not supported natively by Chatto, but as a workaround, you can set up the excellent Pocket ID (which uses Passkeys) and wire it up to Chatto through OIDC. Instructions:

Pocket ID

Configure Pocket ID as an OIDC login provider for a Chatto server.

Very happy to announce that @chatto.run, the amazing little team chat app you can self-host from your own infrastructure (and quite easily so), is now available & Open Source. ✨

Working on some copy for the @chatto.run self-hosting docs

Chatto is a fully-featured, web-based chat application that you can self-host for free. If you’ve used any of the big chat apps — no matter if it’s the one that rhymes with “knack” or the one that rhymes with “beams” or the one that rhymes with “this gourd” — then you know pretty much what to expect.

Except: it’s tiny! It comes with strong privacy properties (it’s made in Europe, we have laws here!) You can just put it on a cheap VPS and host a little chat community for you and the two friends you’ve made in World of Warcraft, or scale it across multiple processes, servers, or even regions, for your 8000 person company!

It has rooms! Threads! Replies! Notifications! File attachments (with built-in thumbnail generation, video transcoding, and GIF processing!) DMs! Voice and video calls with screen sharing! Full-text search! Heaps of configuration options! Flexible role-based access control! SSO integration! And more is coming!

And it ships in a compact ~70 MB executable that you can just plop on a server and run.

Random Chatto Fun Fact: We didn't want to cram the executable with megabytes of notification sounds, so instead Chatto is synthesizing all of them at runtime through the miracle that is the Web Audio API. Some are even slightly randomized! Pew pew pew!

Random Chatto Fun Fact: Chatto works fully air-gapped, if that is somehow relevant to you! Zero external dependencies, zero external assets loaded. Put it on your favorite battery-powered computer, find your five best friends, and move into the woods like you've always wanted.

Pretty happy with the new stuff shipped to Chatto this week, especially the loading and UI responsiveness optimizations. Chatto was already pretty snappy to begin with, but now it's just sublime. Really enjoying being able to polish this thing now. Come join us in the official community!

Giving Chatto's RBAC UX a much-needed overhaul

A permission matrix. Vertical axis is permissions, horizontal is roles. Allows/Denies can be inherited through the tiers (instance, space, room), with inherited permissions shown in faded colors. Clicking cycles through overrides.
