Every MUD. One Monster. MudMonster is a modern, full-featured client for Multi-User Dungeons (MUDs) — the original text-based multiplayer RPGs — built for your pocket. Connect to any MUD, automate your play, and pick up right where you left off across devices. CONNECT TO ANY REALM - Save unlimited connections and jump into any MUD over a fast, native connection. - A true terminal with full ANSI color, light and dark color themes, adjustable fonts and text size, and speedwalk. AUTOMATE EVERYTHING — no coding required - Reflexes: run commands or scripts automatically when text matches (exact, contains, or regex). Built-in pattern helpers, a live tester, and ready-made recipes make it easy — with optional sandboxed scripting for power users. - Aliases: turn short commands into full ones (type "kw" for "kill wolf"). - Timers: fire actions on a schedule. - Variables: store and reuse values across your reflexes, aliases, and timers. LIVE GAME DATA (GMCP) See your world at a glance with an on-screen Game Overlay: - HP / MP / MV vitals bar and XP bar - Room map - Group members, active effects, and channel chat — reorder them however you like. PLAY WITH YOUR THUMBS Floating radial and directional controls send your most-used commands with a swipe. Dwell on a direction to reveal quick hold-actions, and drag the controls anywhere on screen. MANY CHARACTERS, ONE APP Give every character its own profile and avatar, scoped to each connection. MudMonster remembers who's who.
