About

Project Goals - Runtime Crash Handling: Automatically catches React component errors via a standardized Error Boundary. - Professional UI: Replicates the clean and recognizable Cloudflare error page design, including status codes, Ray IDs, and timestamps. - Automatic Error Detection: Intelligently analyzes error objects to determine appropriate HTTP status codes (e.g., 400 for logic errors, 502 for runtime crashes).
