The AI-native creative engine
An AI asset workbench with a full game engine inside. Generate images, audio, video and 3D, then ship in open formats. Work in the editor, or drive it from any AI IDE like Cursor or Claude Code using MCP. Cloud models for quality, local models for privacy.
Built for the way things get made now
AI generates the content. The engine executes deterministic rules. You stay in control of both.
A real AI harness, not a chat box
Cross-referenced skills chain modalities into coherent sets — “create a character” becomes an icon, dialogue audio, a 3D model and stats with one identity. AI agents are first-class users.

Local & private, by choice
Generate on your own GPU for free — your data never leaves your machine. Or route to cloud models for maximum quality. Never a silent fallback.
No lock-in — either way
Everything exports to open formats. And drive Hexaliz via MCP from Cursor, Claude Code or any agent — the editor is optional.
Lightweight & fast
Small install, runs on modest hardware — not tens of GB.
Generative assets, deterministic logic
AI creates the content. The engine executes physics and rules deterministically.
Human in control
Agents do the doing; you inspect, correct and direct. Never a black box.
No in-game shops, no microtransactions, no pay-to-win — in our games or our tools.
Responsiveness and clarity over photorealism. Fun is the spec.
Open, readable files make mods and shared workflows natural — WC3 → DOTA spirit.
One workbench for the whole pipeline
Image, audio, video, 3D and code — with a real game engine when your project needs one.
AI image generation + Photoshop-like editing, local or cloud.
Workflows-as-code in Python — not visual nodes.
Drive everything from AI agents, no GUI needed.
Games are the final boss of AI asset creation
That's why the engine is built in — and why we prove it by building whole games. Same prompt, isolated environment: a plain AI agent vs the same agent inside Hexaliz. Honest results — 5–10 benchmark titles planned.

Underwater survival
“Build a minimal underwater survival game: swim, manage oxygen, collect resources, avoid a patrolling creature, reach the surface to win.”
- ✓ Minimum playable loop verified: swim + oxygen + resources + creature AI + win/lose states
- ✓ Runs both native in Hexaliz Engine and as a browser export from the same open assets
Hexaliz Engine · Python ECS · TOML/JSON assets · three.js export
The methodology
- One game prompt, fixed scope.
- Run it standalone — plain agent, no engine.
- Run it in Hexaliz — engine + MCP + skills.
- Compare assets, logic and completeness.
One company, one thread: agent-first software
The engine is the flagship — and it sits inside a wider ecosystem we build in Sweden.
AI-native game engine + asset editor. This site's main event.
Agent-instruction tooling: route, sync and score AI instructions across IDEs. CLI + platform.
Local-first LLM lab: small fine-tuned coding/reasoning models on consumer hardware.
Excidium, Elysium, Blob Wars — original titles built alongside the engine.
