A space-themed idle RPG of skilling and crafting. Mine, refine, research, and automate your way from a lone ship to an industrial empire. Level skills to 100, engineer your fleet for auto-battler combat, and Warp to prestige. No energy gates, just numbers that climb forever.
Relaxing
Crash-landed on an alien world, you rebuild from scrap through five connected skills, real combat and deep crafting, while progress keeps ticking with the game closed. Play in short check-ins or long grinds, solo or with friends, and climb back toward the stars.
Relaxing

Relaxing
An idle RPG about drifting between islands, leveling skills and crafting better gear. Play it actively or let it run while you are away, then come back to progress waiting for you. Hand-drawn pixel art, a world map to uncover, and plenty of numbers going up.
Minimalist, Relaxing

Command a mining fleet that never clocks out. Train skills across mining, salvage, refining and combat, automate them with drones, trade on a player-run market, and forge the legendary Vanguard hull. Everything runs server-side, so your fleet keeps working while you sleep. Log in to progress you actually earned.
Minimalist, Relaxing
Explore a procedurally generated galaxy, mine asteroids, refine minerals, colonize planets, build stations, deploy drones, salvage rare items, construct gear, level up, improve your ship, assemble a fleet, engage in combat, and take on the void.

Drifter is an open-world sandbox space trading game with a procedurally-generated galaxy 100,000 light years across made up of tens of thousands of star systems to explore and features an original soundtrack by composer Danny Baranowsky.
Atmospheric, Relaxing
An idler about a station guard patrolling space: shoot enemies and asteroids, mine ore, research tech, then spend the spoils on your ship and station. Automation slowly takes over the busywork, so the game mostly runs in the background while you drop in, tweak a build and watch the numbers climb.
Relaxing
An idle incremental adventure in space! Mine asteroids while fighting off enemy AI drones. Build your own AI drones, mining lasers, helper drones and more. Collect hundreds of rewards and unlock a variety of features that will help your ultimate goal: making numbers go up (or sometimes down).
Relaxing
A space trading idler where you start with one rusty hauler, ferry cargo between stations, and slowly grow a fleet of up to twenty ships. It is a game about waiting, and it says so upfront. If watching numbers grow over hours sounds like your kind of evening, this is it.
Minimalist, Relaxing
Unnamed Space Idle is a long sci-fi idle game about holding back alien waves after humanity is nearly wiped out. You fit your ship with weapons and defenses for specific enemies, then stack up 10+ growing systems that feed your power. Its strength is steady, thoughtful tinkering with real choices. Good for patient optimizers.
