WordPress plugins your AI agent can work with
Each of these plugins makes your WordPress site an MCP server, so Claude, Cursor, VS Code and other AI assistants can do real work on it, signed in as you and limited to what you are allowed to do.
Zinn® Cache: free, with an optional Pro add-on
Start with the free plugin. Add Pro only if you want to see what your cache is doing and make it faster still.
- Zinn® Cache is free on any WordPress site: a page cache on any web server, a Redis object cache and purging by tag. It is already installed on every WordPress site we host. About Zinn® Cache
- Zinn® Cache Pro is a paid add-on that installs on top of it: cache analytics, a slow-query finder, a faster object cache, warm-up and lighter pages. It is sold separately, with a free trial, and is not included with hosting. About Zinn® Cache Pro
Everything about the Zinn® cache plugins, on their own site
Which of the two plugins you need, a benchmark measured on a real site, step-by-step guides from installing to clearing the cache and turning on Redis, and fair comparisons with WP Rocket, LiteSpeed Cache, W3 Total Cache and WP Super Cache.
One panel in wp-admin, on every Zinn® plugin
Every plugin here adds the same small panel to your WordPress dashboard: the user guide for each plugin you have installed, and links to the services it works with. It is the same guide we link from this site, so there is one article per plugin rather than two that drift apart.
Download
No account and no sign-up. Each file is served from our own infrastructure with its SHA-256 checksum beside it, so you can confirm that what you downloaded is what we published.

Updates
On a site we host, these plugins are configured to update themselves: they check with us and WordPress installs the new version for you, with the download verified against its published checksum first. On a WordPress we do not host, there is nothing to configure and nothing phones home — come back to this page when you want the newest version, or watch the plugin's GitHub releases.
Need an older version?
Customers can download the newest release of each of the two previous major versions of every plugin in the Zinn Digital® app. It is there for a site that cannot run the current version yet — one still on an older WordPress or PHP — and for rolling back an update that caused a problem. When you can, install the current version.
Licence and source
Every plugin here is released under the GNU General Public License and its full source is on GitHub, so you can read exactly what runs on your site before you install it. They are built to WordPress.org plugin-directory standards: coding standards, security review, no PHP notices, and translation-ready in every language we sell in.

Get help with a Zinn Digital® WordPress plugin
Ask a question, report a bug or send feedback about Tranzly or Page Builder Sandwich. You do not need an account: we answer at the e-mail address you give. If the plugin is installed and working, its own Get help screen can also tell us about your site for you.
LiteSpeed Partner Zinn Digital® is an official LiteSpeed Partner. Every site on our own Zinn® fleet runs on licensed LiteSpeed Enterprise with the LSCache plugin — the fastest way to serve WordPress and WooCommerce — tuned, licensed and kept up to date by us, never the free build.
Questions
Are these plugins free?
The free editions are: free to download and use, with no account, no sign-up and no licence key, under the GNU General Public License. The Pro editions are paid upgrades that unlock more with a licence key. Every WordPress site we host comes with 3 of the free plugins already installed.
Do they work with the latest version of WordPress?
Yes. Before any release is published we install and activate it on a fresh copy of the current stable WordPress, with WooCommerce alongside, and load the front end and the admin — a release that raises a single PHP notice does not ship. The "Tested up to" column above is that test, not an estimate.
Do I have to host with you to use them?
No. They install on any WordPress site on any host. Some features need our platform — the cache plugins need a LiteSpeed server with the LSCache module, and the connector and reseller toolkit talk to your Zinn® account — and each one degrades gracefully where a capability is absent.
How do I know the download has not been tampered with?
Each row shows the SHA-256 checksum of the file we published, and the download itself returns the same value in an X-Zinn-Package-SHA256 header. Compare it against the file you received. The plugins' own updater performs the same check automatically before WordPress installs anything.
How do updates reach my site?
It depends on where the site is. On a site we host, the plugin is already configured against our update service: it checks for a new version, verifies the download against the checksum we published, and WordPress installs it — you do nothing. On your own WordPress the plugin has no credentials for our service and does not contact us at all, so you update it the way you would any manually installed plugin: download the new zip from this page and upload it. We are building a self-service update channel for that case; until it ships, this page is the place to check.
Can I read the source before installing?
Yes — each plugin links to its public GitHub repository above, where the complete source, the licence and every release are available.
How many plugins are there, and is this all of them?
There are 17 in total and every one has a page here. Most can be downloaded from this site and installed on any WordPress. Zinn® Footprint is not distributed separately: it comes installed on every WordPress site we host. The Pro editions are paid upgrades, delivered with a licence.
These plugins run our own hosting
They are not add-ons we sell you. They are how we run more than 700,000 sites, and they come switched on and kept current when you host with us — nothing to install and nothing to update.
