The Spider's Web brings the tools you reach for mid-session into one place — a relationship mapper, dice, generators, and an initiative tracker — that work in person or online, for any system, free and without a login. Pro adds the session planner, journal, sheets, and more.
Map NPCs, factions, locations, and plot threads on an interactive web. See alliances, rivalries, and secrets at a glance, and hide nodes from players until the reveal.
Full dice notation — 3d6+2, advantage/disadvantage, keep-highest, Fudge dice, percentile — with a saved roll history. Works for any system.
Instant NPCs with personalities, quirks, and goals, plus taverns, shops, settlements, plot hooks, and rumors. One click drops a result straight onto your map.
Run combat with auto-sorted turn order, HP, timed conditions, and one-click d20 initiative for every NPC. Pull combatants straight from your campaign.
Start fast from mystery, faction-war, heist, and royal-court templates, then share a read-only, secrets-stripped map with your players via link.
The whole toolkit above is free. Pro is for GMs who want the deluxe campaign bible — richer NPCs, exports, and long-campaign organization — and it keeps the lights on.
Free, no login required, your data stays in your browser. Bring your D&D, Pathfinder, or homebrew world to life on the web.
