Port Boss

Find a harbour and grow it into a global trade empire. A free idle tycoon - no install, no account, no paywall. Build, trade, prestige at your own pace.

ound a harbour on a wild, glowing coastline and grow it into a global trade empire. Port Boss is a free idle tycoon — no account, no paywall. Open it and play.

Build & grow — fishing huts, cottages, markets, factories and docks across eight ages, from a fishing village through a near-future automated harbour to a neon-futuristic megaport.

Living timeline & fleet — advancing the ages remodels your harbour and modernises a fleet you commission and evolve, from rowboats to solar trimarans; build a navy to auto-defend your coast.

Trade network — link your ports into routes for passive income across the map.

Expeditions & relics — send ships on timed voyages that pay out even while you're away; collect relic sets for permanent bonuses.

Storms & pirate raids you can watch — storms darken the sky, corsairs sail up to your quay, and buildings rise behind paper scaffolds.

Legacy & doctrines — prestige for permanent multipliers, then specialise down a branching doctrine tree.

No pay-to-win, no loot boxes, no expiring pressure — Port Boss stays generous and lets you play at your own pace.
