Memory Scan – PHP Memory Usage – No Crash
·
Measures your site's real PHP memory headroom, ranks plugins by expected peak, recommends a memory_limit for your site type, and warns of a crash.
Memory Scan tells you, in plain terms, whether your WordPress site has enough PHP memory to run reliably — and warns you before a low-memory crash instead of after.
Rather than guessing from a single admin page (which is one of the lightest requests on a site), Memory Scan records the real peak memory of each request type — front-end, admin, AJAX and cron — and judges your headroom against your PHP memory_limit with a built-in safety margin.
What you get:
- Real measured headroom — based on the heaviest actual request seen, not a synthetic number.
- Three at-a-glance metrics — current headroom, recommended-for-your-site-type, and real peak by request — that escalate from “You’re fine” to “Urgent” as memory gets tight.
- Per-plugin expected-peak ranking so you can see which plugins (page builders, SEO suites) demand the most memory. This figure is a deliberately conservative estimate, not a live measurement — WordPress cannot bill runtime memory to a single plugin — so it errs high to keep your site safe.
- A recommended
memory_limitfor your detected site type (simple blog, Elementor, WooCommerce, or a heavy stack). - A proactive warning that appears on every admin page when memory is low — so you are told without hunting for it.
- A
WP_MEMORY_LIMITcheck that flags when it is set below your PHPmemory_limit, with the exactwp-config.phpline to fix it.
Memory Scan is read-only with respect to your content: it never changes your posts, pages, or other plugins’ settings. It only reads memory figures and writes its own small diagnostic values.
