Lightsail CDN Cache Manager

Lightsail CDN Cache Manager is a focused WordPress cache manager built around one job — Lightsail cache clear, done right. If your site runs behind an Amazon Lightsail content delivery network (CDN) distribution, this plugin puts you in full control of that cache: a manual clear, an auto cache clear the moment you publish, or a scheduled cache clear on a recurring timer — all from your WordPress admin, no AWS console required.

Use it to manually purge your Lightsail CDN cache with one click, fire an auto cache clear the instant you publish or update content, or set a scheduled cache clear so your cache invalidates itself on its own — daily, weekly, monthly, or at custom intervals.

Why Use This Plugin?

If you’ve wished WordPress cache management for Lightsail was as simple as clicking a button, this is it:

• Built specifically for Amazon Lightsail — not a generic CDN plugin awkwardly bolted on; it speaks the Lightsail API directly using AWS Signature Version 4.
• No stale content after publishing — auto-clear on publish/update means visitors never see outdated cached pages.
• Set-and-forget scheduling — interval, weekly, or monthly cache clears with a live countdown so you always know when the next clear runs.
• Credentials never touch the database — AWS keys live in wp-config.php only, never exposed in the admin UI or REST API.
• One-click connection test — verify your AWS Lightsail credentials and distribution name are correct before you ever rely on it.

External Services

This plugin connects to the AWS Lightsail API to perform CDN cache invalidation operations.

AWS Lightsail API
