PatchOn Agent for WordPress Plugin Directory

PatchOn is an AI service that runs your WordPress plugin, theme, and core updates for you. It reproduces your production site in a staging environment, lets AI verify whether each update can be applied safely, and applies only the updates that pass every check to production. If an update ever fails, one click restores your site. This plugin acts as the agent connecting your WordPress site to PatchOn.

Getting Started This plugin requires the PatchOn service (patchon.jp) and does not function on its own. Activation alone performs no external communication and does not redirect you. Clicking “Start PatchOn” on the welcome screen opens a consent dialog describing the data that will be sent; confirming it with “Agree and Start” registers your site anonymously and, if updates are available, starts the first inspect-and-update run. No account is required to get started — you need one only to:

view detailed inspection results

configure automatic updates

use paid features

Main Features

Pre-inspection — in a staging environment, AI compares before / after screenshots of your site to detect layout breakage and fatal errors

Inspect and update — a manual run goes from inspection to production rollout in one action, applying only updates that passed every check

Automatic updates with inspection — the site is inspected on a schedule and only updates that passed every check are applied

Backups — taken automatically right before each update and downloadable for a plan-based retention period

One-click restore — if an applied update fails, one click puts your site back to the pre-update backup

This plugin (the free distribution on WordPress.org) does not write patched code to your site files, even when it detects a problem. AI auto-repair, which fixes the code causing a problem found during a pre-inspection, is provided by the separately distributed PatchOn Agent Pro extension plugin (available to paid plan subscribers). This plugin writes to your site files in only two cases: applying the updates themselves through the standard WordPress upgrader, and the one-click restore, which runs only on your explicit request and writes your own backed-up plugins, themes, MU plugins, and wp-content drop-ins (and your database) back to the site.

Data Sent Once you have consented on the consent screen, running a “Pre-inspection” or “Apply update” sends the following data to PatchOn and related external services. See the Privacy Policy for details.

Site URL / WordPress version / PHP version / DB version

List and versions of installed plugins, themes, and MU plugins

List of available updates (names and versions of plugins, themes, and WordPress core). While the site is connected, this is sent automatically once a day

Site files prior to update application, used for the pre-update backup: wp-config.php, active and to-be-updated plugins and themes, MU plugins, and wp-content drop-ins (such as object-cache.php)

Contents of WordPress debug.log (used to detect issues)

A full copy of your site’s database, taken during a pre-inspection and reused as the pre-update backup. It may include personal data stored on your site, such as member accounts or contact-form submissions

External services This plugin depends on the following external services. No external communication is performed merely by activating the plugin; it starts only after you explicitly click the “Agree and Start” button on the consent screen shown on first use.

PatchOn API (https://patchon.jp and its subdomains) The backend for all inspection, repair, update, and database-dump operations. Two host names are used, both operated by Rocketa Inc. and routed to PatchOn’s infrastructure:

https://patchon.jp/api/* — site registration, pre-inspection control, apply-update control, billing

https://dump.patchon.jp/* — database-dump control endpoints and signed-URL chunk uploads for pre-inspections and pre-update backups

Provider: Rocketa Inc. (rocketa.co.jp)

When data is sent:

On click of the “Agree and Start” consent button (one-time): anonymous site registration and UUID issuance

Once a day while connected (daily check-in): the list of available updates and plugin version

When the user runs a “Pre-inspection”, or when automatic updates run their scheduled inspection: list of plugins / themes, debug.log, full database copy

When the user runs an “Apply update”, or when automatic updates apply an update that passed every check: a backup (site files and a full database copy) and the application result

When the user runs the one-click restore after a failed update: restore control requests and progress status (the backed-up files and database themselves are downloaded from cloud storage at that time, not sent)

What is sent: see the “Data Sent” section above

Uploads and downloads are performed only against pre-signed URLs issued by PatchOn on a per-request basis. The customer site does not hold any S3 credentials. During a one-click restore, the backed-up site files and database chunks are downloaded from S3 in the same way.
