Space Builder Idle

Start with a small furnace and build your space base, one module at a time. Hire workers, automate production, build an Artificial Sun and assemble your own ship. Use Prestige to start again with permanent upgrades.

It all starts with a small furnace.

Gather your first materials and build your first facility. Watch an empty platform become the start of your space base.

Build more. Produce more.

Hire workers and add new modules to your base. Watch workers carry materials and assembly robots keep production moving.

Build your own sun.

Watch an Artificial Sun take shape, piece by piece, until it lights up. Keep developing your base and increase its production.

Connect your growing base.

Build a Hub Terminal and watch freight trains carry their loads. Expand your research facilities, all the way to a Deep Space Lab.

Assemble your own ship.

Watch each section come together to form a ring-shaped ship. Your space base keeps growing, one construction at a time.

Prestige and start stronger.

Spend earned Prestige Points on permanent passive abilities. Choose your upgrades, start a new run and build faster than before.
