A complete 2D and 3D game studio in a tab. Build worlds, characters, rules and multiplayer without code, then publish once: your game is hosted at its own address and installs on phones, tablets and desktops like any other app.

The studio

Everything a game needs, in one place.

Five workspaces cover the whole job: Scene, Art & Assets, Systems, Setup and Code. Switch between them without a rebuild, an export or a second application.

Scene editing, live

Place props, draw walls and floors, light the scene and drop trigger zones inside the running world. Press Preview and walk it.

  • Snap, grid and gizmo tools
  • Multi-floor maps with stairs
  • Undo, autosave and scene history

Art without leaving the tab

Block out 3D models from primitives, paint pixel sprites and tilemaps, or upload your own GLB files. A shared library adds thousands of ready models.

  • Model Studio with boolean ops
  • Pixel Studio with clips and palettes
  • Material and texture presets
Learn more

Characters that already move

Every project ships a rigged biped with 45 clips. Map your own model onto it, or auto-rig it, and the whole library plays on your art.

  • Locomotion, combat, social, traversal
  • Custom rig mapping and auto-rig
  • Patrol routes and placements
Learn more

Rules, not code

Gameplay is written as plain when, if, then sentences. Zones, scores, items, quests and win conditions, all from a picker. Scripts when you want more.

  • 8 events, 10 facts, 11 actions
  • HUD, audio, data and cutscenes
  • HollowScript with granted capabilities
Learn more

Multiplayer built in

Flip a project to Co-op or Versus and players see each other move and share rule state automatically. Nothing to author, nothing to host.

  • Presence and live movement
  • Shared variables, quests and outcomes
  • Players join from a link, no account

Hosted and installable

One publish puts the game at its own address, kept for every version. Players open it in a browser or install it to their home screen.

  • Public, unlisted or off
  • Every version restorable
  • Install on desktop and mobile

Publishing

A real game at the end, not a demo link.

Publishing is not an export step you run somewhere else. It is one button, and what comes out is hosted, versioned and installable.

Hosted at its own address

Every project claims a permanent play address the first time you publish. Players open it and the game streams into the tab. No launcher, no download, no account.

Installs like an app

Published games carry an app manifest, so players can add them to a phone home screen or a desktop. It opens full screen with your icon and name.

Every version kept

Each publish is a snapshot with a note. Roll back in one click, compare what changed, and take the play address with you when you rename the game.

Nothing to install to make it.
Everything needed to install it.

Soulstack Originals

Five games already live on it.

We build and ship our own games on the same engine, editor and hosting you get. Sunder, our tactical shooter, runs on a dedicated match server. The rest run exactly the way your project will.

Your first game is a browser tab away.

In active development. Nothing to install to build it, and a real app at the end.
