When a component throws in production, your users see a white screen. You get no alert, no context, no clue. DeepTracer catches every error, investigates the root cause with AI, and sends you the fix — in plain English.
user.subscription is undefined on first render — the auth context resolves after the component mounts. The dashboard tries to read user.subscription.plan before the data arrives.
Add a loading guard before accessing subscription data:
React errors aren't like server errors. They're silent, context-free, and often invisible until damage is done. Here's what's lurking in your app right now.
A single component throws. Without an error boundary, the whole React tree unmounts. Every child component disappears. Your users stare at a blank page while you have no idea it's happening.
Your fetch returns a 500. No exception is thrown. React renders with undefined data — showing empty states, broken layouts, or stale content. No error boundary fires. Nothing to catch.
Async state updates fire after a component unmounts. Missing dependency arrays cause stale closures or infinite re-renders. These never throw — they just slowly degrade your app's performance and your users' experience.

@deeptracer/react package works with any React app regardless of bundler or framework. For Next.js specifically, we also have a dedicated @deeptracer/nextjs package that hooks into the App Router and tracks server-side errors too. For Lovable and Bolt apps, the generic React package works out of the box.<DeepTracerErrorBoundary> around your existing boundaries, or replace them — both work. If you already have React Error Boundaries, DeepTracer augments them with AI investigation rather than replacing the fallback UI you've built. You keep full control of what users see; we handle the investigation.@deeptracer/nextjs package which instruments both client components and server-side rendering errors. For pure client-side React apps, the @deeptracer/react package covers all client component errors including those triggered by server data.A component will throw. A fetch will fail silently. A useEffect will leak. The only question is whether you'll find out first — or hear it from a user.
