Cloudflare

Cloudflare is best understood as infrastructure between the visitor and the origin. It can move work to the edge, but the origin website still needs to be healthy.

BEST FOR

Where this tool makes sense.

Websites that want managed DNS and edge delivery with the ability to cache content and reduce work reaching the origin server.

NOT IDEAL FOR

Where we would look elsewhere.

Anyone expecting an edge network to repair inefficient application code, oversized pages or an underpowered origin automatically.

INDEPENDENT TOOL PROFILE

What this tool actually does — and where it fits.

What Cloudflare actually is

Cloudflare is an edge-network platform. A website can use Cloudflare for authoritative DNS and proxy traffic through Cloudflare’s network before the request reaches the origin server.

That position lets Cloudflare cache content closer to users, apply request/response rules and provide additional network/security services without moving the WordPress installation itself.

What caching changes

Cloudflare describes its cache as geographically distributed storage for frequently accessed content. When an eligible response is already cached near a visitor, the origin server does not need to generate or transmit that content again.

This can reduce latency and origin load, especially for static assets and visitors far from the hosting region.

Capabilities worth understanding

  • DNS. Domains can use Cloudflare’s authoritative DNS even before advanced features are configured.
  • CDN/cache. Cache rules control what content can be served from the edge and for how long.
  • Purge controls. Cached content can be invalidated when the origin changes.
  • Tiered caching. Frequently requested content can be distributed more efficiently across Cloudflare’s network.
  • Rules and Workers. More advanced projects can modify request/response behaviour or run code at the edge.

Important limitations

Cloudflare is not the origin host. If a request cannot be cached and the WordPress application takes four seconds to respond, Cloudflare cannot make the PHP/database work disappear.

Aggressive caching can also break dynamic behaviour if login, cart, account or personalised responses are treated as public pages. Cache rules need to understand the application.

Cloudflare and WordPress caching plugins

An origin cache and an edge cache are not automatically duplicates. The origin cache can make PHP requests cheaper; the edge cache can stop many requests reaching the origin. The important part is coordinated purge and bypass logic.

Portability

Cloudflare can usually be removed from a conventional website by changing DNS and proxy configuration, but the more a project depends on Workers, rules and Cloudflare-specific storage/services, the more deliberate an exit becomes.
