Automatic cache purge sync

Hooks into your cache plugin so every purge is mirrored to Bunny CDN. Per-URL purges are used where the cache plugin supports them, instead of wiping the whole zone. Purges triggered during one request (post saves, plugin, theme and core updates, cache plugin clears) are combined into one Bunny API call at the end of the request, after your local cache has finished clearing.

Supported cache plugins (18):

WP Rocket
LiteSpeed Cache
W3 Total Cache
WP Fastest Cache
WP Super Cache
FlyingPress
Swift Performance
Hummingbird
Cache Enabler
Breeze (Cloudways)
WP-Optimize
SpeedyCache
Super Page Cache (WP Cloudflare Page Cache)
ZiziCache
RunCache (Beta)
SWIS Performance by EWWW Image Optimizer
BerqWP
xSpeed Cache

Edge rules that look after themselves

One click deploys a complete set of rules to your Bunny pull zone: HTTPS redirect, HTML caching for visitors, admin and logged-in bypasses, ecommerce, membership, LMS and booking bypasses, long browser caching for assets, query string handling, CORS for fonts, Shield WAF exceptions and security headers. Rules are tracked by GUID, so redeploying never creates duplicates, and rules you created yourself in the Bunny dashboard are left alone.

You do not have to remember to redeploy:

Rules redeploy in the background as soon as the plugin is updated, reinstalled from a zip or activated, using the new version’s code.
Rules redeploy when a supported ecommerce, membership, LMS or booking plugin is activated or deactivated.
A check every five minutes catches anything missed.
A manual deploy always takes priority over a pending automatic one.
Only what changed is sent to Bunny. A redeploy with nothing new costs one API call, and rules stay in place the whole time.
Bulk updates are spread out. After an update pushed from a dashboard, by WordPress auto-updates or WP-CLI, each site waits its own fixed slot of up to 5 minutes, and at most two sites on one server deploy at the same time.
If Bunny rejects a rule, automatic retries back off (5 minutes, 15 minutes, 1 hour, 6 hours, then daily) and the admin notice tells you which rule failed and why.

Bunny Shield WAF, without locking yourself out

Bunny Shield is a powerful WAF, but WordPress admin screens, the block editor and page builders send requests that WAF rules often flag. This plugin turns Shield off for those areas for your team only, and keeps inspecting everyone else.

The bypass uses a cookie holding a per-site secret, so it cannot be forged. Rotate the secret from Settings at any time.
Choose which roles get the bypass. The default is Administrator and Editor.
Covers wp-admin, the REST API for logged-in users, the Bricks builder and code editor, WordPress 7.1 media processing and this plugin’s own admin files.
Trusted IP whitelist: turn Shield off for specific IPs or CIDR ranges, such as payment gateways, SaaS callbacks, office networks or staging servers.
Shield WAF event log on the Stats tab: blocked IPs, triggered rules and URLs for the last 1, 6, 24 or 72 hours.

Security headers

Sets the six response headers that securityheaders.com grades on, at the Bunny edge, so they apply to cached pages too: Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy and Permissions-Policy.

The defaults are safe for any WordPress site. HSTS is set for one year without includeSubDomains or preload, and the Content-Security-Policy restricts framing and plugins without blocking the inline scripts WordPress and most themes rely on. Developers can replace any value with the wpbc_security_headers filter.

Remote management: MainWP, ManageWP, InfiniteWP, WP Umbrella, Modular DS, Watchful and UpdraftCentral

Putting Bunny in front of sites you manage from a dashboard can cause slow syncs, sites reported as disconnected, and long updates that run twice. The plugin fixes this for every major remote management service:

Trusted dashboard IPs. Once the service itself has verified a request as coming from its dashboard, that dashboard’s IP is added to the Shield trusted IP rule. Unverified requests are never trusted, learned IPs expire when the dashboard stops using them, and at most 5 are kept per service.
No timeouts or repeats. Pull zones wait the full 60 seconds for the origin and never resend a timed-out request, so a long update or sync never runs twice.
Nothing private is cached. One-click login links, connect links and WP Umbrella requests always bypass the CDN cache.
Calm bulk updates. Updates pushed from a dashboard are spread out per site, and at most two sites on one server redeploy at once.
Status at a glance. The Integrations tab lists each service and the IPs it is trusted from.

MainWP extras. On the MainWP Dashboard, requests to child sites running this plugin go straight to their origin server, skipping the CDN, its WAF and its 60 second limit. Each origin is checked before use and rechecked weekly, and sites that cannot be reached directly keep using the CDN. The Integrations tab shows each child’s status plus server cron and timeout recommendations.

WP Umbrella extras. Umbrella’s login protection is given Bunny’s edge server list, so it sees each visitor’s real IP instead of a Bunny server, and Bunny is purged whenever Umbrella clears caches.

Works with Nahnu Login Shield

Nahnu Login Shield is our free login security plugin. It locks out brute-force attackers and can push their IPs to the Bunny.net WAF, so they are blocked at the CDN edge before they ever reach your server. It reuses this plugin’s Bunny connection, so there is nothing extra to set up. Its status and a one-click install are at the top of the Integrations tab.

Ready for WordPress 7.1

WordPress 7.1 processes images in the browser using about 13 MB of WebAssembly and JavaScript. Bunny Optimizer is kept off those files, and Shield is turned off for them for your team, so image uploads in the block editor work with Shield and Optimizer active. These rules deploy only on WordPress 7.1 and later.

Ecommerce bypass

Bypass rules are built automatically from each plugin’s own page settings. No manual URL entry needed.

Supported ecommerce and donation plugins (6):

WooCommerce
SureCart
FluentCart
Easy Digital Downloads (EDD)

Tutor LMS
FluentCommunity

Affiliate and community plugins with bypass rules (2):

SureDash

Booking and event bypass

Supported booking and event plugins (4):

Events Manager

Multilingual support

When WPML, Polylang or TranslatePress is active, bypass rules include translated page URLs automatically, and the pull zone varies its cache by Accept-Language so each visitor gets the right language.

Cache warmer

After a full purge, a background job crawls your sitemap to pre-warm the CDN edge. It requests one page at a time, at most two sites warm at once on the same server, and it waits while the server is busy, so warming never competes with real visitors.

Supported SEO plugins for sitemap auto-detection:

Yoast SEO
Rank Math
All in One SEO
SEOPress
SlimSEO
The SEO Framework
Squirrly SEO
WordPress core sitemap (fallback)

Live CDN analytics

Pull zone stats, DNS stats, bandwidth breakdown, cache hit rate, Shield WAF events and cache sync status, all inside WordPress admin.

Perma-Cache cleanup

Deletes stale Perma-Cache files from Bunny Storage right after a full purge, without waiting for them to expire.

Automation: WP-CLI, REST API and PHP hooks

WP-CLI: wp bunny deploy, wp bunny purge, wp bunny status, wp bunny rules
REST API under /wp-json/wpbc/v1/: GET /status, POST /purge, POST /purge-url, POST /deploy. Authenticated with a token from Settings or a WordPress admin session.
PHP API for other plugins: check the connection, read status, purge, deploy and reuse the Bunny connection.

The API tab in the plugin shows every endpoint, filter and action with copy-paste examples.

External services

This plugin connects to the Bunny.net API (api.bunny.net) to purge cache, manage edge rules and pull zone settings, and retrieve statistics, and to Bunny Storage when Perma-Cache cleanup is enabled. When WP Umbrella is active, it also downloads Bunny’s public edge server IP list (api.bunny.net/system/edgeserverlist) once a week; no key or site data is sent with that request. On a MainWP Dashboard, it checks whether each child site’s own origin server answers directly; those requests only go to your own sites. An active Bunny.net account and API key are required. No visitor data is sent. See the Bunny.net Privacy Policy and Terms of Service.

Privacy Policy

Nahnu Cache Connector for Bunny.net does not collect or send any data about your site’s visitors. No analytics, no tracking, no third-party data sharing.

The plugin talks to the Bunny.net API to purge cache, fetch statistics and manage edge rules. The data sent is limited to your Bunny API key (in request headers), pull zone and Shield zone IDs, your site’s hostnames and the URLs to purge. On sites managed by MainWP, ManageWP, InfiniteWP, WP Umbrella, Modular DS, Watchful or UpdraftCentral, the IP address of the managing dashboard is stored on your site and added to your own Shield trusted IP rule. For UpdraftCentral this can be the IP of the administrator’s browser; it is deleted after 7 days without use. See Bunny.net’s Privacy Policy for how Bunny.net handles this data.

No data is sent to Nahnu Plugins or any third party other than Bunny.net.
