Stop losing players to silent crashes

Error tracking built for web games. Capture every crash with a 6-second video replay, full device context, and the game state that caused it.

Get Started Free See Features

Watch the crash happen. Not just read about it.

Every error comes with a video recording of the last 6 seconds before the crash. See exactly what the player saw — the frame drops, the visual glitches, the moment it all went wrong.

Everything you need to squash game bugs

One script tag. Zero config. Full crash context.

Full Device Context

Browser, OS, GPU renderer, screen size, memory, CPU cores, touch capability — 40+ device fields captured at the moment of crash.

Performance Timeline

FPS history, frame-by-frame delta times, heap memory growth, long task blocking time, and Web Vitals — all correlated to the crash moment.

Network & Assets

Last 100 requests with timing and status. Failed image/script/audio loads. No headers or bodies captured — privacy by default.

Player Input History

Last 200 input events — clicks, touches, gamepad axes & buttons, scroll, pointer pressure. Keyboard activity without individual keystrokes.

Smart Error Grouping

Errors are fingerprinted by stack shape, not message text. One entry per bug, not thousands of noisy duplicates.

Privacy-First Design

No raw user agents, no request bodies, no keystrokes logged. URLs are stripped of query params, console logs are scrubbed for PII, and IPs are hashed.

One-Line Integration

Add a script tag and call init(). No build step, no bundler plugin, no config files. Works with Phaser, Three.js, PixiJS, or vanilla canvas.

Every signal that matters. Automatically.

Other tools give you a stack trace. Error Buddy gives you the full picture.
