Overseer Studio is a desktop application built for tabletop gaming that organizes all the tools a GM uses to run their games. It's not a VTT and it's not a new tool to learn. Overseer Studio simply makes running your games easier and more streamlined. Overseer Studio is offline-first and runs on any Windows, macOS, or Linux computer.

Overseer Studio isn't meant to replace your existing tools. It's meant to work with them and keep you more organized during a game.

For example, if you use OneNote, Obsidian, or any other campaign organizer, you can embed these tools into Overseer Studio for quick access during a game alongside all your other tools and materials.

Running a session can often be chaotic with lots of moving parts. Overseer Studio helps you consolidate your tools into one, easy-to-use screen.

Overseer ships with a handful of useful tile extensions including:

• Notepad with markdown support
• Styled text tiles
• Image tiles
• Video tiles
• PDF tiles
• Audio tiles
• dddice
• Website embeds; and
• VTT tiles for Roll20, Foundry VTT, and Owlbear Rodeo

You can also easily build your own extensions!

Yes! Overseer Studio was built to be modular by design. You can create extensions, presets, and themes for Overseer Studio and share them however you'd like.

Extensions are embedded websites and can be built with simple HTML, CSS, and JavaScript. You can use the injected Overseer SDK to hook into application events and communicate or listen to other extensions.

$15 for early access users. Once features are finalized, Overseer Studio will be $30 for everyone else. Overseer Studio is a one-time purchase, no subscription fees, with free updates as they're made available.

No. Overseer Studio is offline-first and does not provide a way for players to connect. This also means you do not need to configure ports or host your own server to use Overseer Studio.

If you want to share a particular tile with your players, you can pop out a tile into a new window and share the window over a video call or cast to your living room TV.

As a GM myself, I know how frustrating managing 20 tabs and 5 different programs can be just to run a session; especially when one of your players decides to go off the rails and you're forced to improvise. The last thing you need is the software you're using to get in the way. That's why I built Overseer Studio.

If you were once familiar with Astral TableTop or more recently dddice, then you might know the person behind those tools as the person behind Overseer Studio.

I've learned a lot since building those platforms. The biggest lessons have been:

• There are tons of amazing TTRPG tools out there and people will mix and match what works for them,
• Tools feel better when they're simple to use with no strings attached; and
• No one wants to experience an outage during a session.

Overseer Studio was built differently, taking a decade of experience building tabletop gaming applications and applying the lessons learned to make one cohesive, modular, offline-first tool to rule them all.

I'm always open to feedback or questions, email me anytime at tom@overseer.studio.

There is no timeline but the goal is mid-2026. If you want to be a beta tester, please send me an email.

Beta testers will receive a version of the product that will be buggy and possibly unstable at times. They have the unique opportunity to hunt down major bugs and provide influential feedback before the software is released to early access users.

Early access users will receive a more polished product that will be infinitely less buggy with a better user experience.

If you're interested in becoming a beta tester, please send me an email.
