Description

Boring Cache Warmup Lite is a lightweight, practical WordPress plugin that warms up your cache. It runs from your own site, does not connect to external services, and keeps the job boring, transparent, and privacy-friendly.

Boring tools, because they simply work.

The plugin does not use external services, tracking, cloud queues, external APIs, or CDN-hosted assets.

It is intentionally lightweight: small plugin files, local requests, conservative batches, and no extra frontend baggage.

Current free version features:

Tools submenu page in the WordPress admin.
Dashboard widget with a direct warmup button.
Lightweight design with small plugin files and no external runtime dependencies.
Nonce-protected AJAX calls.
Published pages, posts, products, and public custom post types.
Conservative batch processing to reduce timeout and overload risk.
Progress bar and status messages.
Manual stop button.
Live crawl log with status, duration, and HTML payload size.
Technical post types such as Elementor templates are excluded by default.

Installation

Activate the plugin through the Plugins screen in WordPress.
Open Tools > Boring Cache Warmup Lite or use the dashboard widget.

FAQ

Does this plugin use an external service?: No. The plugin only loads URLs from your own site, from within your WordPress installation.
Can this overload my site?: The plugin uses small AJAX batches and a short delay between batches. Very large sites should still test carefully and may need custom limits in a later version.
Do I need to keep the warmup page open?: Yes. The warmup runs through AJAX requests from your browser tab. Keep the tab open until the run is complete. You can continue working in other tabs or browser windows.
What happens if I close the tab during warmup?: The current request may finish, but no new batches will be started. Nothing dramatic happens; just open the tool again and start a new warmup run.
Does the plugin use my XML sitemap?: No. The Lite version does not use sitemaps. It collects published public content directly from WordPress.
Which URLs are warmed?: The plugin starts with the homepage and then collects published public posts, pages, products, and public custom post types. Technical post types such as attachments, templates, reusable blocks, and editor data are excluded by default.

It does exactly what it’s supposed to. I’m looking forward to more features and am curious to see how the Boring Cache Warmup plugin will continue to evolve.
