WE BUILD GAMES.
SO WE BUILT THIS.

Tombstack is made by AnkleBreaker Studio, the team behind the Unity game Mithrall. We got tired of finding out about crashes from one-star reviews — so we built the tool we wished we had, and pointed it at our own game first.

The story

Mithrall is a live-service game, and live-service games crash in ways you can't reproduce on your own machine. We needed to see a spike form in real time, group 40,000 crashes into one actionable grave, and let an AI do the first pass of triage at 3am.

What started as an internal crash-aggregator became something we thought every studio deserved. So we rebuilt it as a standalone, multi-tenant platform with its own SDK, dashboard and MCP server — and kept Mithrall as customer number one, the build that stress-tests every release before you ever see it.

Dogfood, always

Mithrall is customer #1. Every feature ships to our own live game before it ships to yours — if it can't survive a Mithrall launch night, it doesn't survive at all.

Your data is yours

EU data residency in Paris (eu-west-3), 90-day retention, and one-click player erasure for GDPR. Export your raw data anytime. No lock-in, no hostage analytics.

Built for the AI era

The MCP server is a first-class surface, not an afterthought. We expect your crashes to be triaged by an AI as often as a human — so we designed for both.
