What is crawlers.cc?

crawlers.cc is a free GM tool for running Dungeon Crawler Carl tabletop RPG sessions. If you’re game-mastering a crawl through the books’ deadly dungeon, or the official Renegade Game Studios Dungeon Crawler Carl RPG releasing October 31, 2026, it handles the fiddly parts: generate a dungeon floor, reveal it tile by tile as your party explores, and keep everyone at the table looking at the same live map. Character stats, loot, achievements, and session notes stay tracked in one place, and your secrets stay on your side of the screen.

How it works

  1. Generate your floor. Sign in and open the GM console. Generate a dungeon floor for your next crawl.
  2. Share your session code. Players join from their phones or laptops; no account needed, and they see the live player map.
  3. Reveal tile by tile. The table explores together while traps, loot, and monsters stay hidden until you reveal them.

Frequently asked questions

What game is crawlers.cc for?

The Dungeon Crawler Carl tabletop RPG, based on Matt Dinniman's book series. It works alongside the official Renegade Game Studios RPG (out October 31, 2026).

Is crawlers.cc free?

Yes.

Do my players need accounts?

No; they join your session with a code and watch the live map.

What do I need as the GM?

A free account, plus approved GM access. Running games and the AI generation tools are gated behind a quick review — see “How do I become a GM?” below.

How do I become a GM?

Sign in, then request GM access from your dashboard with a short note about the games you want to run. An admin reviews each request — usually within 2 days; you'll get an email when it's decided, and your dashboard shows the status in the meantime. If a request is denied you'll see the reason and can reapply.

Does it use AI?

Yes; floors, rosters, and boss content can be drafted by an AI model (Cloudflare Workers AI). It's a starting point you can edit, AI-generated content is badged in the app, and generation has reasonable per-account limits to keep the free service sustainable.

What data do you store, and can I delete it?

Your account (email + display name via Auth0), the characters and campaigns you create, and AI-usage records. You can delete your account anytime from your character list. See the Privacy and Terms pages for details.

Is this an official product?

No; it's an independent, fan-built GM tool, not affiliated with Matt Dinniman or Renegade Game Studios.
