Hoshi
Hoshi is a cross-platform Spacebar client built with Flutter, currently in devlopment. Expect bugs. Well, what does that mean?
Hoshi works on:
- iOS
- Android
- Web
- Windows
- Linux
- macOS
The web version will be available when the first release is out. You'll be able to try it on https://hoshi.oh64.moe.
As the only maintainer of Hoshi, tests are made for Linux and Android only. I may test the Windows version sometimes. There may be some testing on iOS by someone I know who has an iPhone, but it remains very basic.
On what devices will it be tested?
- Android: POCO X6 Pro (Unofficial Voltage OS 5.2 | Android 16) and Mi 10 (Official MIUI 12.0.3 | Android 10)
- Linux: Arch Linux (as default stratum, with kernel Linux 6.17.9-arch1-1, using GNOME Wayland) with Bedrock Linux installed above it
- Windows: Atlas OS 11 (no specification needed)
- Web: Zen Browser (Firefox and Chrome), on the official instance and a private one

That's temporary. I want to make it stable and learn Flutter all by myself. Plus, Hoshi uses Sentry (with messages and images not shared), because I want to learn how to use it. So yeah, it will be open-source one day.
Is Hoshi stable?
The latest version (0.1.0) isn't stable. It can crash, there are cache and optimisation issues, some behaviours aren't fully implemented (like in settings). It has 0 fail-safe: for example, if it doesn't understand a server response, it just doesn't care and renders it anyway.
Why are some texts in French?
Hoshi was originally meant to be used only by me (so I started doing everything in French, bad idea, I would've translated it anyway). I tried to translate everything, but bruh, I may have missed something.
Will Hoshi have themes and plugins?
Hoshi won't have a theme or plugin, but Hoshika will, though that's for later :3
Does Hoshi work with old Spacebar server versions?
Maybe, but that would only be luck. Hoshi will only support the latest Spacebar version at build time.
Does Hoshi work with the official Discord?
no, doin't try, no no no
Who is on the Hoshi icon?
It represents nobody. It's just there because I don't know how to make a proper icon. It may be removed in future versions. I lost the ibispaint file.
Hoshi doesn't work with my server!!!
Hoshi is dumb but it has been corrected, please check your configuration carefully.
Remember when I said I wouldn't make a guild? Well, actually I did, so I could have all the bugs in one place. https://fermi.chat/invite/10HJSc?instance=https%3A%2F%2Fspacebar.chat
When will an update be released?
when I feel like it
Can I self-host the web version?
Nah. And anyway the code can only work with my URL because I didn't prepare it.
