This is awesome! Some feedback - I can't tell anywhere from the website if there is mobile support (which is a must-have if I want to consider moving my company or friends over to this)
It is indeed planned, but in the meantime it does also have first-class PWA support, so you can easily install the webapp as a mobile app on mobile devices. Works great on Android.
Chatto currently commits to providing a strong PWA experience that also works great on mobile (including full support for voice and video calls, push notifications, the works.)
I am aware though that a lot of people would prefer an app that they can install, so this will be coming at some point -- just not a huge priority at the current point in the project's timeline.
Note that to send notifications to an iOS app, the app publisher has to send them. This means that they need to run an event forwarding proxy service (this is how Mattermost and Element/Matrix and presumably some/all of the ActivityPub clients do it), or selfhosting your server means you must also selfpublish your client app via the App Store and Apple’s developer program tax.
For Mastodon, each mobile app developer needs to have a "webpush relay server" to receive Mastodon's webpush notifications and transmit them to the platform's push service. For Android, Mastodon recently added support for the latest webpush standard which allows the app developer to directly register Google's webpush endpoint with Mastodon, removing the need for a relay.
In all cases, push notifications are encrypted by the Mastodon server, and decrypted by the Mastodon client, so any intermediaries (relay server, push notification service) can not read their content.
Also, toss in a quick description. I couldn't tell quickly from the post or site what Chatto _is_. I guessed a vibe coded LLM TUI because that's the new hotness. In a world of Yggdrasil and Immich and Czkawka, a very brief intro helps!
