Hi — I've built Mappadux (mappadux.com), a free, open-source VTT for in-person tables. I built it for my gaming table as I was sick of different apps that take ages to setup to be useful. VTT tools themselves are designed to be used online and my local shop has no Internet access.

As there are no strings attached and it has some useful bells and whistles I was hoping map creators use it to bundle maps + audio + fog + markers into a single file with your own splash, banner, and Patreon links. Players click on your link in a browser — no account, no install. Calibrated 1″/25 mm projection too if you GM around a real table and immersive features like visual filters (Watercolour or Glitchy CRT), transitions and positional audio. To support creators every asset travels with its licence + a 'Copy attributions' action so credits are baked in. You can also password protect the files to keep within your community.

Hope you take a look - feel free to ask questions! Yes... I did this for fun... that is all!

About a year ago I popped an early version of this program on here which peeps liked. One of the main criticisms was that it required to be "installed" - this is a TOTAL rewrite that means it "just works" from a browser. It is effectively a very light form-over-function VTT tool you can use locally or online for free.

No account needed. No server. Everything stays on your device — maps you upload are stored in your browser's local storage and never sent anywhere. Just open the link and go. Remember to save off your map setups as you go - exporting bundles all your maps and config into a single json file for easy transport.

Creators - feel free to create a "map pack" with all your maps with filters & FoW and link to this app to show them.

For those new to this it is a browser-based tool for tabletop roleplaying game GMs. It lets you display map images to players in real time, with full control over fog of war, visual filters (greenscreen shown above), pan and zoom — all from a separate GM interface. Players or a player window the GM can share connect via a peer-to-peer link (your own security permitting!).

I added a few new filters in this release too:

Filter	Style
None	Unfiltered (with optional invert)
Ballpoint Pen	Hand-sketched ink drawing
Hand Drawing	Hatched cross-hatch with halftone colour
Oil Painting	Painterly impasto brush strokes
Parchment Fantasy	Aged sepia parchment with candlelight
Retro Sci-Fi Amber	Warm amber-phosphor CRT terminal
Retro Sci-Fi Green (SHOWN IN PIC)	Classic green-phosphor CRT terminal
Watercolour	Soft watercolour wash

I would love feedback on how it works for you, if you run into issues and what features you would like to see.

This is what has been added since I made this initial post:

1. Map transitions — fade and wipe animations when switching maps on the player view.
2. Markers / tokens — place and manage visual tokens on the map.

These are future features I plan:

1. Audio (started) — ambient sound tied to maps (done) or locations/markers (Optional... Aliens-style motion tracker).
2. Lighting — dynamic light radius effects around tokens. (maybe)

Some thanks:
