SnapTrace Error Monitoring System

### Why we built SnapTrace Most error tracking tools in 2026 were built over a decade ago for monolithic backend servers. When imported into modern Next.js and frontend environments, they introduce serious technical debt: * 100KB to 150KB+ added directly to client JavaScript bundles. * Synchronous breadcrumb serialization on the main UI thread that damages Google Core Web Vitals (INP). * Unfiltered alert storms: an infinite React re-render loop can trigger 50 duplicate emails in two minutes. SnapTrace was built from the ground up as a zero-bloat, privacy-first telemetry alternative. --- ### Key Features: ⚡ **Sub-5KB Client Footprint:** Zero dependencies. Strictly under 5KB minified so it doesn't penalize your client bundles. ⚡ **0ms Main-Thread Delay:** Telemetry dispatches asynchronously via native `navigator.sendBeacon()` (with keepalive fetch fallback) to protect your Lighthouse and Core Web Vitals scores. ⚡ **On-Device PII Regex Firewall:** Automatically scrubs passwords, authorization headers, credit cards, and sensitive tokens in the browser before the payload ever touches the network. ⚡ **60-Second Loop Throttling:** Detects rapid re-render loops in-memory and collapses duplicate crash bursts into a single `[x50]` incident. ⚡ **Cascading Outage Collapse:** Groups multiple downstream symptom errors into one root-cause incident so you don't spend hours connecting dots by hand. ⚡ **1-Click AI Fix Prompts:** Exports context-rich debugging prompts formatted specifically for Cursor, Claude Code, and VS Code Copilot. --- ### Try It Without Signing Up: We built an open interactive browser sandbox where you can test live crash ingestion, loop throttling, and regex PII masking in real-time: 👉 **https://snaptrace-dashboard.vercel.app/test** Free tier includes 5,000 events/month.
