MITHOS Reimagines the Game Master’s Screen: A Digital Toolkit That Every GM has Been Waiting For
A solo developer has created a one-time purchase, system agnostic Game Master’s suite, putting an end to subscription fatigue. The platform organizes all a Game Master’s needs and puts them into one place.
St. Petersburg, FL – April 5, 2026 – Independent developer, Michael DeLeo was tired of running multiple programs, needing multiple browser tabs open, and juggling subscription services in order to run live tabletop role playing games. His answer is MITHOS, the modular system-agnostic digital toolkit for Game Masters. “MITHOS began as a single tool to solve a problem at my own table, but it quickly snowballed into a full suite that I realized other GMs could actually use,” says DeLeo.
MITHOS is set to launch summer of 2026, and is available to wishlist now on Steam. The software will deliver a high-performance, locally-stored alternative to current market offerings. Built on a decade of dungeon-mastering experience, the toolkit prioritizes speed and privacy, operating entirely offline with a one-time purchase model. “To me, privacy is a right and subscriptions are gross; plain and simple. I have been in close communication with the Mithos Discord community, and I am incredibly honored by how supportive and helpful they have all been of my vision for this platform. I am glad to be able to give back to the TTRPG community.”
A New Standard for the Digital Screen
MITHOS replaces the cluttered, tab-heavy experience of traditional TTRPG software with a workspace built for the speed of live storytelling. Unlike platforms that force users into a specific workflow or subscription, MITHOS is defined by:
- Total System Independence: While many tools are locked into specific rulesets, MITHOS is designed to be truly system-agnostic. Whether you are running high-fantasy, sci-fi, or a homebrewed gritty survival horror, the toolkit adapts to your rules; not the other way around.
- The Boundless "Infinite" Canvas: Most digital tools trap you in rigid grids or nested menus. MITHOS utilizes a free-panning, scrollable workspace that mimics a physical table, allowing GMs to spread out their Non Playable Characters, maps, and trackers exactly where they can see them at a glance.
- Zero-Tab Integration: MITHOS is built to live with your existing workflow, not replace it. By allowing GMs to view and update external notes from Obsidian, OneNote, or Notion directly within the dashboard, it eliminates the "Alt-Tab" immersion break that kills session momentum.
- Localized & Offline Reliability: In an era of cloud-dependency and "software-as-a-service," MITHOS provides absolute reliability. With 100% local storage and no internet required, your campaign is always accessible, your data is local, and your game will never be interrupted by an internet outage or a paywall.
- Dual-Screen Mastery: Designed specifically for the modern table, MITHOS allows GMs to manage the "behind-the-curtain" mechanics on one screen while projecting a clean, immersive map for players on a second display or digital TV table or player facing combat tracker.
