    Remix Monitoring

    Loader/action error tracking and uptime monitoring for Remix apps.

    What typically breaks on Remix

    • Loader 500s cascading into root ErrorBoundary
    • Session cookie domain mismatch after custom-domain switch
    • Form action POSTs blocked by stale CSRF tokens

    What Lemwatch checks on every Remix site

    HTTP uptime

    1-minute checks from multiple regions. We catch Remix-specific 5xx errors, not just connection timeouts.

    Response time + Core Web Vitals

    TTFB, LCP, CLS, INP tracked over time. Alerts fire when the rolling baseline degrades, not just on hard outages.

    Content integrity

    We diff your homepage HTML and key routes. Catch silent deploys that strip critical content or break routing.

    SSL + DNS drift

    Cert expiry warnings 30 days out. DNS hash watch alerts when A/CNAME/MX records change unexpectedly.

    Works with where you deploy Remix

    Lemwatch monitors the public surface, so it doesn't care which host you use. Common Remix hosting stacks we see in the wild:

    Vercel
    Fly.io
    Cloudflare Workers
    Netlify

    How we detect Remix

    When you add a site, Lemwatch fingerprints the stack from the public response — in Remix's case, by looking for __remixManifest payload and /build/ asset paths. Detection is non-invasive and runs on every health check, so a stack migration surfaces in your changelog within 24 hours.
