✨ Features

Everything you need to run a clean, up-to-date add-on setup — and nothing you don't.

• 📦 One home for everything installed. Addonarium scans your ESO AddOns folder, shows every add-on with its version, and flags exactly what's out of date. Hit Update all and walk away — dependency libraries are tucked into their own section so the list stays readable.

• 🔍 The entire ESOUI catalog, instantly searchable. Thousands of add-ons with live search and filters by type and game version. Preview screenshots and the full change log, then install with a single click.

• 🧩 Dependencies handled for you. Required libraries (LibAddonMenu and friends) are detected and installed automatically, and every download is checksum-verified. No broken add-ons, no manual hunting.

• 🔗 Share your whole setup as a code. Export your installed add-ons to a short build code and send it to a friend or your guild — they recreate your exact loadout in one click. Save named builds and switch between them with a clear install / remove preview.

• 💾 Backups you can trust. Snapshot and restore your add-ons before big changes — optionally including your SavedVariables, so all your in-game settings come back too.

• 🎨 Made to look good. A modern Material 3 interface with light and dark themes and a custom accent color. Fully localized in English and Русский.

📥 Download

Grab the latest build from the Releases page — no Java and no setup required, the runtime is bundled.

Platform	Get it
🪟 Windows	Addonarium-<version>.exe or .msi — installs with Start-menu & desktop shortcuts, no admin needed
🍎 macOS	Addonarium-<version>.dmg — drag it to Applications
🐧 Linux	addonarium_<version>_amd64.deb, or install from the AUR (addonarium-git) on Arch

First run: Addonarium asks for your ESO AddOns folder and pre-fills the usual spot — …/Documents/Elder Scrolls Online/live/AddOns. You can change it any time in Settings.

🔒 Verifying your download

Builds aren't code-signed yet, so Windows or macOS may warn about an unknown publisher — expected for a small open-source project. To stay safe:

• Checksums. Every installer on the releases page ships with a matching .sha256 file. Check it before running — e.g. on Windows:

  Get-FileHash Addonarium-<version>.exe -Algorithm SHA256

  or sha256sum -c Addonarium-<version>.exe.sha256 on Linux/macOS.
• Windows SmartScreen: click More info → Run anyway.
• macOS Gatekeeper: right-click the app → Open (first launch only).

🌐 Website

The landing page and an in-browser pack decoder live at addonarium.arakoto.dev — paste a pack code to see exactly which add-ons it contains, then open it straight in the app via an addonarium:// deep link. Source is in site/.
