Dust765 is a ClassicUO fork built for serious Ultima Online players — fast, cross-platform, and packed with combat features. No drama. Just UO.

The Project
Dust765 was born from frustration — not with Ultima Online itself, but with the drama, gatekeeping, and clique culture that had crept into its open-source tooling ecosystem.
We took ClassicUO, stripped the politics out, and focused on what actually matters: a fast, stable, cross-platform client that respects every player regardless of what OS they run or who they know.
"This project was created to show the community that open source isn't meant for cliques and high school drama — it's meant for the expansion of something greater: innovation."
— A penny for your thoughts, the adder that prays beneath the rose.What We Built
Every feature below was added because players asked for it — not because someone in a Discord inner-circle approved it.
Last target tracking, self-cast support, stun/mortal highlight, swing line indicators for ranged weapons, sync position on attack, and UO Classic Combat integration.
Glowing weapons, highlight friends and guild members, gargoyle fly state override, custom gargoyle walk animation while flying, and health indicator overlay.
Active spell icon on cursor, OnCasting gump, self-cast last target highlight, and fast rotation support for fluid spellcasting.
Custom window title bar with HP/Mana/Stamina bars (UOS/Orion-style), borderless window mode with resize edges, and a redesigned login screen.
Native builds for Windows x64, Linux x64, and macOS. All platforms are treated equally — first-class support, not an afterthought.
Razor Enhanced, UOStealth, UOAssist, ClassicAssist, and other popular plugins all work out of the box. No manual patching required.
Built-in auto-loot system, UO Classic Combat macro helpers, action bar, and scriptable macro support for repetitive tasks.
Configurable nameplates, health bars, info bars, cooldown bars, counters, and an in-game buff bar — all customizable per profile.
Integrated update manager checks for new releases and applies them automatically so you never miss a patch or have to hunt down downloads.
