CrashSight, developed by Tencent WeTest, is a professional crash and exception management platform built specifically for game developers. It provides real-time crash capture, reporting, and multi-dimensional data analysis across mobile (iOS, Android), PC (Windows, Linux), and console (PlayStation, Xbox, Nintendo Switch) platforms — helping teams quickly identify root causes, reduce crash rates, and improve player experience. CrashSight integrates natively with Unreal Engine, Unity, and Cocos via lightweight SDK plugins, with a C interface available for proprietary engines. The SDK captures crashes, ANRs, and script-level errors (C#, Lua, JS), and reports detailed context including full error stacks, trace data, register info, loaded libraries, and system logs. Beyond standard crash reporting, CrashSight offers gaming-specific intelligence that general-purpose tools lack. Its proprietary OOM detection algorithm uses an app runtime state machine combined with device-specific memory thresholds to accurately classify out-of-memory crashes — a category invisible to traditional signal-based capture. A big-data approach to emulator identification achieves 10–15% higher accuracy than conventional methods, with separate crash statistics for real devices, emulators, and cloud gaming environments. Advanced capabilities include automated feature analysis with customizable rule-based issue tagging, version-to-version quality comparison, single user/device timeline tracking, longest common subsequence analysis for custom data, and a configurable alert system supporting Slack, Jira, DingTalk, Feishu, WeCom, email, and webhooks. The real-time dashboard refreshes every 10 minutes and supports 20+ search dimensions for exception filtering. Trusted by major game studios worldwide, CrashSight monitors over 200 million daily active users across its customer base. The platform is globally deployed with data centers in the US, Singapore, and Shanghai, ensuring full data compliance and overseas data residency.
