About

Starbound Idle is a browser idle game about building up a spacefaring pilot one skill at a time. Pick a skill, tap a task, and your character keeps working while you plan the next step. Skills are grouped into gathering (like Xenobotany and Gas Siphoning), Processing (Refining, Electronics, Galley, Chemistry), Crafting (Engineering, Fabrication) and Action (Piloting, Combat).

Everything you collect lands in your Cargo Hold, where items can be filtered by type such as Fuel and Food. Select an item to see where it comes from, what it makes, and whether to sell or use it. Your ship also has sections for Equipment, Ship Modules, a Star Map and a Market.

A directive track gives you guided goals with credit rewards, starting with simple tasks like mining 10 Copper Ore from a Copper Asteroid. Keep an eye on your credits, total level and HP from the top bar, and check the Recent Loot panel to see what your work has earned.
