Q: Beta channel?

Separate updater endpoint or beta flag in JSON manifest listing compatible versions.

Ship Rust desktop apps with installers, code signing, and safe auto-update channels.

Recipe

# Tauri
cd src-tauri && cargo tauri build
 
# Plain Rust + cargo-bundle
cargo install cargo-bundle
cargo bundle --release

When to reach for this:

First public release to non-developers
Enabling in-app updates without manual downloads
macOS notarization to pass Gatekeeper
Microsoft Store or Linux flatpak distribution

Working Example

Tauri updater config sketch (tauri.conf.json fragment):

{
  "plugins": {
    "updater": {
      "endpoints": ["https://releases.example.com/{{target}}/{{current_version}}"],
      "pubkey": "dW50cnVzdGVkIGNvbW1lbnQ6IG1pbmlzaWduIHB1YmxpYyBrZXk6I..."
    }
  }
}

What this demonstrates:

HTTPS endpoint template per target triple
Embedded public key verifies update artifacts before apply
Version gating prevents downgrades if configured

Deep Dive

How It Works

Build produces release binary + assets.
Bundle wraps in .dmg, .msi, .deb, or .AppImage.
Sign attaches publisher identity (Apple, Authenticode).
Updater downloads signed bundle diff or full package.

Platform Notes

OS	Artifact	Signing
macOS	`.dmg` / `.app`	Developer ID + notarize
Windows	`.msi` / NSIS	Authenticode cert
Linux	deb/AppImage/flatpak	GPG for repo metadata

Gotchas

Unsigned macOS build - users get scary dialogs. Fix: notarize in CI with Apple credentials.
Hard-coded dev paths in bundle - crash on user machines. Fix: runtime path resolution only.
Updater without HTTPS - MITM installs malware. Fix: TLS + signature verify mandatory.
Missing universal macOS build - Rosetta friction on Apple Silicon. Fix: aarch64-apple-darwin + x86_64-apple-darwin lipo or separate artifacts.
Debug symbols in release - huge downloads. Fix: split debuginfo or strip for release lane.

Alternatives

Alternative	Use When	Don't Use When
Homebrew cask	Dev tool CLI/GUI	Non-technical consumer users
Microsoft Store	Enterprise deployment	Need custom updater day one
Portable zip	Internal tools	Consumer double-click install expected
Docker	Server apps	Desktop GUI with GPU

FAQs

Tauri vs cargo-bundle?

Tauri includes updater, signing hooks, and WebView assets; cargo-bundle is minimal wrapper for pure Rust GUIs.

Where to store signing secrets?

CI secrets (GitHub Actions) with hardware token or cloud HSM - never in repo.

Linux packaging choice?

AppImage for universal; flatpak for sandboxed store; deb for apt-based enterprise.

Versioning scheme?

Semver; breaking database migrations bump minor/major and document in release notes.

Crash reporting?

Sentry or similar in Rust layer; symbolicate with uploaded debug symbols from release build.

Beta channel?

Separate updater endpoint or beta flag in JSON manifest listing compatible versions.

CI matrix?

Build macOS on macOS runners, Windows on windows-latest, Linux on ubuntu - cross-compile only when tested.

Icon sizes?

Provide icns/ico/png set per platform guidelines - Tauri icon generator helps.

Legal notices?

Ship LICENSE and third-party notices file for webview and Rust crate obligations.

Framework specifics?

Tauri for web UI; egui/iced use cargo-bundle or installers manual.
