WPColt Cache Inspector

Diagnose your WordPress cache.

You installed a caching plugin, Cloudflare, and Redis. WPColt shows whether any of it is actually working, whether the layers are fighting, and what to fix first.

01 / Diagnosis

Caching is crowded. Diagnosis is the gap.

Most sites do not need another cache switch. They need to know why Cloudflare says BYPASS, why Varnish never gets warm, or why Redis is installed but disconnected.

01

Read-only by design

WPColt tests public requests and reads WordPress/cache signals without changing settings, purging caches, or writing rules.

02

Layer-by-layer proof

Homepage and post checks run twice as a logged-out visitor, then compare headers like Age, X-Cache, X-Varnish, and CF-Cache-Status.

03

Plain-English priorities

The report separates what works, what is broken, what to fix first, and how to verify the fix.

02 / Key Features

Everything a cache audit checks first.

Version one focuses on the questions that decide whether a WordPress site feels instant, stale, unpredictable, or mysteriously slow.

1

Plugin detection

Flags active page-cache plugins and spots obvious two-plugin collisions before you chase server settings.

2

Proxy detection

Looks for Varnish, Nginx FastCGI cache, LiteSpeed, Cloudflare, and other proxy fingerprints.

3

Object cache checks

Reports whether Redis or Memcached appears installed, connected, and useful instead of merely present.

4

Header reading

Turns Age, X-Cache, X-Varnish, Server-Timing, and CF-Cache-Status into HIT, MISS, BYPASS, or unknown.

5

Cookie warnings

Finds cookies and response headers that make public pages uncacheable across server and CDN layers.

6

WooCommerce safety

Checks cart, account, and checkout patterns so private ecommerce pages do not get cached by accident.

03 / Proof

A report your client can understand.

No terminal screenshots. No raw header dump as the final answer. The report keeps the evidence close and explains the next move.

1st

Fix ranked by impact and confidence

What is working

Cloudflare is serving repeat homepage requests from cache. Age increases between checks.

What is broken

Server cache misses every post request because a marketing cookie is sent on public pages.

What to fix first

Exclude the cookie from anonymous visitors or move it behind consent before tuning cache TTLs.

How to verify

Clear caches, run the check again, and confirm X-Cache changes from MISS to HIT on the second request.

04 / Plans

Free first. Pro later when it earns it.

The first release should win trust with a sharp free diagnostic. Paid monitoring can come after the core report is valuable.
