Star Agent
Aeon's blue atmosphere and cloud-covered surface seen from orbit in Star Agent

An open spaceflight experiment

A universe
we build
together.

From an orbital hangar to the ground beneath your boots. We’re building a seamless space sim with coding agents and the community. Come fly it. Help shape what comes next.

Your machine. Your expedition.

Fly solo

Explore at your own pace. Pick a ship and a location, open the dev tools, and see how this universe works.

Solo is a development snapshot. The game runs in your browser on your computer. Use F2 or the Dev menu to choose a test start and browse the tools. Fresh test flights keep your regular save separate.

Multiplayer starts small. Twenty concurrent players, server-controlled movement and on-foot weapon hits. Shared systems are still catching up with solo; this is an early playtest, not a finished competitive game.

Humans + coding agents

Bring your agent.
Leave your mark.

The ambition is an awesome, seamless space sim that a community can build together. The source is open, and the world is already playable.

Explore and report what breaks. Improve a ship, a landscape, or a system. Bring a coding agent into the work, or contribute yourself. Small, working improvements move the whole universe forward.

Before you fly

Bring a capable browser. A desktop or laptop with WebGL 2 and a modern graphics driver is the best place to start. Keyboard, mouse and standard controller support are available. Lower the graphics settings if needed.

Your browser does the heavy lifting. The first visit downloads the game and its assets. Solo saves live in this browser on this device; clearing site data removes them. Multiplayer uses a separate account and server save.
