Post Description

Exactly one year ago today, I got fed up with tab juggling when running my D&D games and decided to build something to organize it all.

VTTs were too cumbersome for me because it required a ton of prep upfront and I still needed to teach my players how to use the software. Tabletop games are most fun when the story flows without friction and so my goal was to make a program that made my life as a GM easier.

Overseer can take any website, PDF, application, and more and place it on an infinite grid. You can add shortcuts to any tile for easy access, resize, move, and rearrange your scenes, and make your GM screen uniquely yours.

It even has plugin support to build your own tiles using simple HTML/CSS/JS.

The power of Overseer is just how simple it is to use and extend.

Today marks the 1-year anniversary of the first commit I made. I wanted to share it here in hopes others find it useful.

Happy gaming!

Multispace -save,organize,and launch workspaces–tools,apps,games,anyURL

The landing page is a tidy coming-soon card with a pleasant gradient and a rocket — visually fine but nothing substantive. The idea (save/launch 'spaces' of URLs and apps) is familiar — Workona/Toby/Station already own this niche — and there's no live demo, screenshots, or technical signals on the page to justify why I'd switch. If the team ships unique primitives (local-first sync, secure session sandboxing, or native app integration) this could matter; right now it's just a neat concept with no evidence.
