Tombstack
Track crashes, exceptions and play sessions.
- Version
- 1.0.1
- Released
- September 2026
1 / 9
The free Unity front door to Tombstack, AnkleBreaker's crash and analytics service for game studios.
It installs the MIT-licensed SDK in one click, pins it to a published version and carries a full manual inside the editor. The service is free for games under 10 peak concurrent players.
Your game runs fine on your machine. Tombstack tells you what happens on players' machines: the exception nobody reported, the crash that left no log, the hang that turned into a one-star review.
Link the project once and the SDK reports on its own: unhandled exceptions on every thread, a rolling session log with each report, unclean shutdowns and out-of-memory kills caught on the next launch, breadcrumbs, session heartbeats for live CCU and crash-free rate, and frame statistics.
Beyond crashes, one-line calls track events, progression funnels, economy sources and sinks, purchases and ad impressions, and players can file in-game bug reports with a screenshot attached.
What you get
Crashes grouped, not piled up
Exceptions, unobserved Tasks and AppDomain failures are grouped by stack signature, so 40,000 crashes become one entry.
Context with every report
A rolling session log and a 50-entry breadcrumb buffer travel with each report, so you see what the player was doing.
Crashes managed code never sees
Unclean shutdowns and OOM kills are caught on the next launch through a session marker.
Performance telemetry
Average FPS, slow-frame percentage, hitch count, worst frame and an app-hang watchdog.
Works offline
An offline write-ahead queue retries across launches, so a player on a plane still reports.
Consent and privacy
With Require Consent on, nothing is captured or sent until your game calls SetConsent(true). Device identifiers are salted on-device and never leave it raw.
AI triage over MCP
The Tombstack MCP server gives Claude or Cursor crash summaries, signature drill-downs, bug reports and triage actions: sixteen tools, one config block.
Pinned and documented
One-click install pinned to a published tag, update notices in the console and a 19-page in-editor manual.
