Quick answer: BugSnag (SmartBear) is a capable error monitor with Unity and Unreal support, but check its platform tables: the Unreal plugin supports Android, iOS and macOS only, and the Unity notifier reports C# errors only on Windows, with limited WebGL support and no listed Linux. For PC, Steam and web games, Bugnet covers every platform your engine exports to, adds an in-game report widget, Steam reviews and a tracker, and costs a flat $19 or $79 a month after a free plan.
BugSnag has a long track record in mobile app monitoring, and many developers reach for it because their studio already uses it for apps. For games, the details of its engine support matter more than the brand. Here is what its own documentation says, as of October 2026, and what to use if it does not cover your game.
What BugSnag supports for games
| Engine | Fully supported | Limited | Not listed |
|---|---|---|---|
| Unreal Engine (UE4, UE5) | Android, iOS, macOS | — | Windows, Linux, consoles |
| Unity | Android, iOS, macOS (C# and native errors) | Windows (C# errors only), WebGL | Linux, consoles |
BugSnag's docs also note that IL2CPP builds on WebGL and Windows report no file names or line numbers. For a mobile game, that is all fine. For a Steam game, it means native crashes on Windows are not covered in Unity and nothing is covered in Unreal.
BugSnag pricing
BugSnag's free plan covers one user with 7,500 events and a million performance spans a month. Its Select and Preferred plans are consumption-based with unlimited users, and Enterprise is custom, with on-premise options. Event-based pricing means a crash wave after a bad patch moves your bill.
What Bugnet covers instead
- Every platform your engine exports to. SDKs for Unity (2020.3+), Unreal 5, Godot 4, GameMaker, Construct 3, Pygame and the web, including Windows, macOS, Linux, Steam Deck, WebGL, Android and iOS builds.
- Engine-level capture. Unity exceptions, errors and failed asserts; Unreal fatal errors and ensures with a native callstack; Godot engine and script errors; browser errors and unhandled rejections. Each report has recent log lines, a screenshot, GPU, RAM, OS, resolution, version and a performance snapshot.
- Player bug reports from an in-game widget (Unreal games call
ReportBugfrom their own UI). - Game-specific extras: Steam review sync, Google Play and App Store review import, a public known-issues page, crash-free sessions per build and a bad-patch check.
- Flat pricing: free for one project and 100 reports; Studio $19 a month for 20 members and 10,000 reports; Studio Plus $79 a month unlimited.
What it does not do: native minidump processing or console SDKs. If you need those, pair it with a dump tool.

Switching
- Create a free Bugnet project and copy its API key.
- Add the SDK for your engine (see the SDK docs) and initialise it at startup.
- Bind the report widget to a key or menu button.
- Run both for a release, compare, then remove the BugSnag notifier from your desktop builds.
Keeping BugSnag for a mobile companion app? That is a reasonable split. For more options, see the best crash reporting tools for Unreal Engine and for Unity.

Read the platform table before you read the feature list. A great tool that skips your platform is no tool at all.
