SceneDiff — AI Runtime Bug Detective

## SceneDiff — AI Runtime Bug Detective Modern software teams release new code every day, but finding which code change caused a runtime bug is still difficult and time-consuming. Git shows code differences, CI pipelines check builds, and monitoring tools report failures, but developers still spend hours checking logs, browser errors, API requests, screenshots, and performance data to find the real issue. SceneDiff solves this problem by connecting Git changes with real browser behavior. SceneDiff compares two Git commits—a stable version and a new version—and runs both versions in isolated browser environments. It captures runtime information like DOM changes, console errors, network requests, browser storage, screenshots, and performance metrics. Then it compares both executions to detect any runtime regression. After detecting a regression, SceneDiff analyzes the runtime evidence along with Git changes to identify the most likely root cause. It tells developers what broke, where it broke, and why it happened by identifying the affected file, function, and confidence score. SceneDiff also includes an AI Repair Engine that generates a Git-style repair patch. Before suggesting any fix, it validates the patch using syntax checks, scope validation, risk analysis, and rollback planning. This makes AI-generated fixes safe and explainable instead of automatically changing the code. ### Target Users SceneDiff is designed for: * Software developers * QA engineers * DevOps teams * Engineering teams investigating production bugs Developers simply provide two Git commit SHAs. SceneDiff collects runtime traces, compares application behavior, finds the root cause, and generates a detailed investigation report with a suggested repair patch. ### What Makes SceneDiff Unique? SceneDiff combines multiple AI-powered debugging features into one platform: * Git-aware behavior tracing. * Browser runtime comparison using Playwright. * Explainable AI root cause analysis. * Secure AI repair patch generation. * Secret Shield security that removes API keys, JWT tokens, passwords, cookies, and other sensitive data before storing any runtime information. ### Why It Matters SceneDiff makes debugging faster and easier. Instead of manually checking different tools, developers get one AI-powered workflow that detects runtime regressions, explains the reason behind them, and provides safe repair suggestions. This helps teams reduce debugging time while improving software reliability and security.
