Tabletop Simulator is a sandbox. This is a D&D table.
Tabletop Simulator can play any board game ever made, which is exactly why it is an awkward home for D&D: the grid, the ruler, the turn order and the minis are all things you assemble from Workshop mods. TerrainTale is only a D&D table, so those are the product, and it runs in a browser tab for free.

What a grid does for a fight
In Tabletop Simulator a D&D map is a table someone built, with a grid someone aligned, minis someone imported and a ruler that measures in table units. It works, and thousands of groups have made it work. In TerrainTale the floor tile is a square, the wall is an edge, the ruler reports feet with your diagonal rule and the height difference, and a Large creature takes two squares by two because the mini knows its size. Nothing is assembled; the grid is the medium.

Building instead of downloading
The room tool, the tile brush and the shelf make a map in minutes from a realistic library of scanned materials, photoscanned props and Meshy-made minis. A scene recipe written by an AI assistant imports as grid-correct geometry. Tabletop Simulator has no builder; its strength is the Workshop, which has a version of nearly everything and a quality range to match.

Where Tabletop Simulator is still the better pick
Hidden hands and any other board game are what the sandbox is for, and TerrainTale does none of that — its own physics dice tray covers the D&D roll, not a general game engine. Hero Forge's paid 3D minis import directly as .unity3d bundles, which no browser VTT can read. TerrainTale's shared rooms now let each player join from their own computer and move their own mini too, but without physics or a general sandbox behind it. If your group meets online and already owns Tabletop Simulator, it is a fine home; if the fight is on a D&D grid, this is the shorter path.
Questions
Can I import my Tabletop Simulator tables?
No. Tabletop Simulator saves and mods are not a format TerrainTale reads. Individual models exported as .glb import directly on Premium.
Does TerrainTale have physics dice?
Yes. A built-in tray throws physics dice over the screen and shares the result with everyone at the table; it tracks HP and initiative too, but it does not automate rolls from a stat block.
Is TerrainTale free like a Steam sale?
Free to use with one saved scene, no sale needed; Premium is $6 a month for up to 200 scenes and your own models. The library is CC0/CC BY and it is self-hostable.
Does it do multiplayer like Tabletop Simulator?
Not the same way. Shared rooms let a link-invited party sign in and see the table live, dragging their own minis, but there is no physics engine and no general board-game sandbox behind it — it is a D&D battle map, not Tabletop Simulator.
