# Sanctum
**A private, self-hosted desktop client for [mithraic.space](https://mithraic.space)**
Built on [Revolt](https://revolt.chat) — open source, no tracking, no telemetry, no nonsense.
Windows & Linux. Auto-updates from your own server.

## What is this?
Sanctum is a custom fork of [Stoat for Desktop](https://github.com/stoatchat/for-desktop), hardwired to connect exclusively to **mithraic.space** — a self-hosted Revolt instance. It replaces the default branding, icons, and update pipeline with a fully self-contained setup hosted on a private Forgejo instance.
No reliance on external services. Updates come from `git.mithraic.cloud`. Builds run on a self-hosted CI runner. Everything stays in-house.
---
## Installing
Grab the latest build from the [Releases page](https://git.mithraic.cloud/ad3laid3/sanctum/releases).
### Linux
```bash
# extract to your local apps folder
mkdir -p ~/.local/share/sanctum
unzip Sanctum-linux-x64-*.zip -d ~/.local/share/sanctum/
# register it as a desktop app
cat > ~/.local/share/applications/sanctum.desktop << EOF
[Desktop Entry]
Name=Sanctum
Exec=$HOME/.local/share/sanctum/sanctum
Icon=$HOME/.local/share/sanctum/resources/assets/desktop/icon.png
Type=Application
Categories=Network;InstantMessaging;
StartupWMClass=sanctum
EOF
```
Then search for **Sanctum** in your app launcher and you're in.
### Windows
Extract the zip, run `sanctum.exe`. That's it.
---
## Auto-updates
Sanctum checks for new releases on every launch. When a newer version is available on `git.mithraic.cloud`, you'll get a desktop notification — click it to download. No background processes, no silent installs.
---
## Building from source
You'll need Git, Node.js, and pnpm (`corepack enable`).
```bash
git clone https://git.mithraic.cloud/ad3laid3/sanctum
cd sanctum
pnpm i --frozen-lockfile
pnpm start
```
### Releasing a new build
Push a version tag and CI does the rest — compiles Linux and Windows builds, creates a release, and uploads artifacts automatically.
```bash
git tag v1.x.x
git push origin v1.x.x
```
### Building locally
```bash
# Linux (deb + zip)
PLATFORM=linux pnpm make
# Windows (zip, no Wine required)
pnpm make --platform win32 --arch x64
```
Output lands in `out/make/`.
