Compatible with Stars Without Number

Run Stars Without Number the way you actually play it.

Sandbox sci-fi — sectors, factions, hacking

Sector maps, faction turns, starship combat, and a hacking minigame that plays out live at the table — built for the sandbox sci-fi you're already running.

A sector that remembers what you built

Drop pins on a hex-grid sector map and every system carries its own world detail — atmosphere, biosphere, tech level, the tags that make a planet feel like somewhere instead of a stat block. Trade routes connect the systems your players actually visit, and the party's ship shows up as a live pin the whole table can see.

It's the same sandbox toolkit from the tabletop rules, just faster to run — no more flipping between three notebooks mid-session to remember which moon has the black-market shipyard.

Factions that move on their own clock

Every faction on the map tracks its own goals, assets, and members, and faction turns resolve in the same tool where you run everything else — no side spreadsheet, no forgetting whose turn it was.

Influence and assets update live, so the political map your players are scheming against is always current, not three sessions stale.

Starship combat without the graph paper

Deck plans, weapons, and cargo live on the same ship sheet your party already knows, and combat plays out on the same initiative tracker you use for a bar fight — no separate ship-combat module to relearn.

A hacking minigame that respects the rulebook

Cyberdecks build attack packets, the GM builds defenses, and the exchange animates live at the table — tense, visible, and fast enough that hacking doesn't stall the session while everyone waits on one player's spreadsheet math.

Comms that feel like FTL, not a group chat

Per-NPC comms threads gate on range and FTL lag, so a message to the far side of the sector actually takes time to arrive. It turns "call for backup" into a real tactical decision instead of an instant chat ping.

Initiative and a battle map that just works

An initiative strip keeps combat moving, and a canvas battle map lets you drag stamps, save the layout, and load it again next session — the tactical layer is there when a fight needs it, and out of the way when it doesn't.
