Artemis LVTT

Local-first virtual tabletop for D&D and other TTRPGs at the same table: run your fantasy battlemap in the editor while the room watches a passive viewer on another display. No server, no accounts. LVTT means local VTT for in-person play—not a full online table with remote players.

I wanted the player-facing scene on a TV or projector and to treat that screen like the playing surface: digital backdrop underneath, physical minis on the glass.

Artemis is a hobby project for our games, but feel free to use it for your own table. Data stays in your browser; export the .vtt file backup regularly if you care about keeping the campaign.

What it does

Projects & scenes. Multiple scenes per project.
Square grid. Spacing you can match to the artwork.
Draw on the scene. Freehand, shapes, and lines.
Spell templates. AoE cones, spheres, cubes, and lines on their own layer.
Fog of war. Reveal brush in the editor. Players view screen always sees full-strength fog for what you have opened up.

Lights. Placed presets plus token-carried lights.
Tokens. Names, sizes, optional portraits; hide tokens from the viewer when you need to.
Ruler. Ephemeral measure tool on the top canvas layer.
Viewer window. Second window for the table: auto-fit, no pan or zoom.
Live sync. Editor and viewer stay aligned on one machine: no server or account.
