Every stack breaks differently. These guides cover the failure modes we see per framework and the checks worth running on each.
Every platform fails in its own way. WordPress breaks on plugin updates and lapsed certificates. Frameworks with build-time rendering break on failed deploys and stale caches. Hosted platforms like Shopify break at the theme and app layer, where the HTTP status stays 200 while the page is quietly wrong.
The failure modes specific to that platform, where the symptom shows up first, which Lemwatch checks catch it, and concern-level pages for uptime, performance, SSL, SEO and content tuned to that stack.
The core checks are platform-agnostic — they run against the rendered page and the network layer, so anything reachable over HTTP can be monitored regardless of what generated it.
