Description
Checkout Profiler measures how long placing an order takes in your shop and writes every measurement to the WooCommerce log. No dashboards, no external service — just numbers you can act on, next to the logs you already have.
View the results under WooCommerce > Status > Logs, source checkout-profiler. Each entry names the order, the duration in seconds and the payment gateway (the gateway usually dominates checkout time):
Classic checkout for order 1234 took 1.311 seconds (payment via stripe).
Both checkouts are supported:
- Block checkout (the default since WooCommerce 8.3): detected automatically, measured in the shopper’s browser from the moment they hit “Place Order” until the checkout succeeds — the time your customer actually experiences.
- Classic (shortcode) checkout: measured in PHP between two hooks. The defaults measure the server-side order processing, including the payment gateway round trip. Works out of the box, no configuration needed.
Configurable for the classic checkout:
- Choose start and end hooks from sensible presets — for example end at
woocommerce_thankyouto include the redirect to the order confirmation page in the measurement. - Or enter any custom hook name for start and end.
What this plugin is not: a full APM suite like New Relic. It answers one question — “how slow is my checkout, really?” — with near-zero overhead: one session value, one log line per order, and a small script that only loads on the block checkout page.

FAQ
-
Does this slow down my website?
-
No measurable impact. The classic checkout timer stores one timestamp in the WooCommerce session and writes one log line per order. The block checkout script (about 1 KB) loads only on the checkout page, and only when the checkout block is actually in use.
-
Is the block checkout supported?
-
Yes, since 1.1.0 (requires WooCommerce 9.8 or newer, where the official checkout events are available). It is detected automatically and measured in the browser — the settings page only applies to the classic checkout.
-
What exactly is measured?
-
Classic checkout: the time between the configured start and end hooks, by default from checkout form submission until the order is processed (server-side, including the payment gateway). Block checkout: the time from clicking “Place Order” until the checkout succeeds, as experienced in the shopper’s browser.
-
Where do I see the results?
-
WooCommerce > Status > Logs, pick the file/source
checkout-profiler. Note: your WooCommerce log threshold must includeinfomessages (it does by default). -
Will this work with my theme/pagebuilder/custom checkout?
-
The block and shortcode checkouts are covered out of the box. For custom checkout flows, point the start and end hooks at any two hooks your flow fires — as long as both fire, the measurement works.
-
Is this like New Relic?
-
Of course not. But it pursues a similar goal for a very specific spot: APM tools instrument your whole stack; this plugin tells you plainly how long your checkout takes, with results stored in the WooCommerce logs you already use.

Changelog
1.1.0
- New: block checkout support — measured in the shopper’s browser via the WooCommerce checkout events API and logged with order number and payment gateway. (The 1.0.0 block timer never loaded; this is a rebuild.)
- New: the log line now includes the payment gateway, since the gateway usually dominates checkout time.
- New: durations are rounded to milliseconds for readable logs.
- Fix: the plugin now measures out of the box — previously nothing was logged until the settings were saved once.
- Fix: the advertised default end hook (
woocommerce_checkout_order_processed) is now actually the default. - Fix: the Settings link on the Plugins screen points to the Profiler settings tab instead of the admin dashboard.
- Fix: empty placeholder scripts and styles are no longer loaded on every front-end page; admin assets load only on the Profiler settings tab.
- Fix: block/classic explanation on the settings screen was never displayed due to an invalid field type.
- Fix: a custom hook selection with an empty hook name falls back to the default instead of silently breaking the timer.
- Compatibility declared with High-Performance Order Storage (HPOS) and the cart/checkout blocks.
- Uninstalling the plugin now removes its settings.
- Text domain changed to
checkout-profiler-for-woocommerceso translations can be delivered via wordpress.org language packs. - Requires WordPress 6.5+, PHP 7.4+ and WooCommerce 9.8+ (declared via Requires Plugins / WC headers).
