There must be some sort of mixup, I'm neither AT Proto native, nor end-to-end encrypted (beyond video/voice calls)!

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 Feature Preview: we've been giving the UI some subtle upgrades - among other things you can now configure how flat or 3D you want it to look (we've been told people prefer different things!)

We're very much looking forward to putting Chatto 0.5 into everyone's hands; it's a significant release with a truly massive number of new features and improvements. It's also going to be one of the last 0.x releases before we go 1.0. Onwards and upwards!

It's Chatto! @chatto.run · 12/09/2026

The Chatto frontend app also now surfaces versions of the servers you're connecting to and gives you a heads-up when a server is using a version that's too old to support. We're working on formalizing a compatibility guarantee for older versions within a specific timespan; stay tuned!

It's Chatto! @chatto.run · 12/09/2026

Chatto 0.5's API now is in a very good shape, in terms of making it easy to build anything from chatbots to entire new frontends, but also in terms of forward and backward compatibility.

120

It's Chatto! @chatto.run · 12/09/2026

Chatto HQ will be upgraded to it, too. Please note that 0.5 is not API compatible with previous versions, so if you're connecting to HQ from your own server's frontend or vice versa, and stuff will suddenly be inaccessible, you know what's up.

It's Chatto! @chatto.run · 12/09/2026

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.

Chatto 0.5 Feature Preview: SEARCH! Finally! Chatto now supports pluggable search backends and ships with a simple built-in backend that will Just Work for servers of all sizes. Find messages through the search page, room sidebars, and the quick finder palette.

A Chatto room with the room sidebar open and its search tab selected. The user is searching for "thread", with search results from that room listed underneath.

The server search page, with the user searching for "chatto". Results are from all rooms the user is a member of.

Chatto may eventually support AT Proto for signing in, but is otherwise not related to the protocol.

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!

Most configuration currently goes through the configuration file/environment variables. There'll be some runtime configuration functionality in future versions, and some of these may move into that in the long run. HTH!

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.

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.
