Upper

Upper automatically purges cache when entries or sections are updated in the Craft Control Panel, eliminating manual cache management headaches.

It integrates easily with Fastly, Cloudflare, KeyCDN, and Varnish through simple environment variable configuration, as shown in the README setup examples.

Developers can disable caching or set custom durations directly in Twig templates using tags like `{% do upper.cache.never() %}` or `{% do upper.cache.for('5 minutes') %}`.

Adds Cache-Control and cache-tag headers (e.g., XKEY/Surrogate-Key) to responses, enabling efficient edge caching and granular invalidation, as demonstrated in the response header image.
