Tombstack

Overview

Tombstack is a game-focused workspace for crash reporting, player analytics, retention cohorts, and release health. It suits teams that want crash investigation and player trends together; its engine-specific limitations make a closer fit for some development stacks than others.

Made by AnkleBreaker Studio, the team behind the Unity game Mithrall, it targets solo developers, independent teams, studios, publishers, and live-service teams. Paris (eu-west-3) data residency, raw-data export, and one-click player erasure for GDPR add useful controls for teams managing player data.

Key features

Crash investigation and retention

Tombstack groups recurring crashes and brings together stack traces, breadcrumbs, and player bug reports with session context. That gives teams more to work with when investigating repeat failures than crash counts alone. Retention comparisons by country, OS, device, and build, including D1, D7, and D30 results, connect release and audience trends to the same workspace. A crash-free users metric is also supported.

Configurable dashboards and integrations

Teams can select dashboard layouts, search a widget library, save views, rearrange and duplicate dashboards, and undo changes. This flexibility helps organize monitoring around different team priorities without requiring a single fixed view.

SDKs are available for Unity, Web/TypeScript, Godot 4, and native C/C++; Unreal is supported through the C ABI. The Godot GDScript addon does not automatically intercept script errors, while a dedicated Unreal plugin and server-side native symbolication are roadmap items. Those limits matter if automatic coverage of those errors is essential.

An optional hosted MCP server provides 37 tools for compatible AI assistants. Automatic advertising-campaign attribution is a separate integration; Tombstack cautions that date comparisons alone do not prove campaign causation.

Pricing

The free plan costs nothing, billed Forever. It allows up to 10 peak CCU, 30-day retention, 1.68M rows per fixed 30-day window, and unlimited team seats. The seat allowance is generous for a free tier, but the CCU, retention, and row caps set clear boundaries for growing or longer-running projects.

Studio costs $1 a month, billed monthly for peak CCU above the free allowance, with graduated rates by band. It adds configurable 30–90-day retention, symbol upload and storage from CI, and Slack/Discord spike alerts. Hosted MCP is an add-on at +€20/mo or $22/mo. This plan fits teams that have outgrown the free caps or need longer retention and operational alerts, though usage-based CCU charges mean the listed starting price is not a flat total.

Enterprise has custom pricing, scoped per engagement, and is not self-serve. It adds self-hosting or a dedicated VPC, extended retention, SSO/SAML, audit logs, console certification support, a dedicated success engineer, and an uptime SLA. Those controls and support suit organizations with deployment or service requirements beyond the self-serve plans.

Platforms

Tombstack supports Linux, macOS, web, and Windows. Its integrations span Unity, Web/TypeScript, Godot 4, native C/C++, and Unreal through the C ABI, with the engine-specific caveats noted above.

Who it's for

Tombstack is a strong candidate for game teams that want crash context and retention analysis in one place, particularly those using Unity or web technologies and needing flexible dashboards. Teams relying on automatic Godot script-error capture or a dedicated Unreal plugin should weigh the current gaps. Studios that need campaign attribution should also plan for the separate integration rather than treating date comparisons as causal evidence.

Pros and cons

• Pros: Crash groups include stack traces, breadcrumbs, and session context, helping teams investigate recurring failures.
• Pros: Retention comparisons by country, OS, device, and build combine useful player analysis with crash reporting.
• Pros: Free plan includes unlimited team seats and up to 10 peak CCU, making it practical for small teams starting out.
• Cons: The free plan is capped at 30-day retention and 1.68M rows per fixed 30-day window.
• Cons: Godot's GDScript addon does not automatically intercept script errors, and dedicated Unreal tooling remains on the roadmap.
• Cons: Studio charges by peak CCU above the free allowance, so its $1 a month entry price does not describe total usage cost.
• Cons: Campaign attribution requires a separate integration.

Alternatives

Choose BugSplat if its free tier's 15,000 crashes per month, 100GB storage, one-month retention, and three user logins better match your reporting needs; it also offers a free trial.

Backtrace is worth comparing for teams seeking a free developer plan capped at 25,000 monthly errors, with one month of retention and 10 GB storage.

Pick Breakpad if an open-source crash-reporting library and tool suite with self-built and self-hosted components is preferable.

Playloop is another freemium option for web and API platforms, with a free plan offering unlimited games and 5 GB storage.

AccelByte Development Toolkit may suit teams focused on build distribution, playtests, and issue reporting, with unlimited basic seats on its free plan.

BugSnag offers a free plan with one user, 7.5K events, and 1M spans per month, making it a comparison point for teams evaluating event and span limits.

KSCrash is a free, MIT-licensed open-source framework for Apple platforms.

NHN Cloud Log & Crash Search uses custom quotes based on the features selected.

Verdict

Choose Tombstack if your game team wants crash investigation and retention analysis together, plus a free tier with unlimited seats and a usage-based route to longer retention and alerting. Look elsewhere if automatic Godot script-error capture or a dedicated Unreal plugin is central to your workflow, or if campaign attribution must be built into the same integration.
