How to Install and Configure Plugins in PKHeX.Web
May 03, 2025
PKHeX.Web offers some basic functionality via a default set of plug-ins. These cover common use cases, but the tool is designed to be extensible.
It also publishes an SDK, in case you have an idea to develop your own plugin to tailor the experience further.
This guide will walk you through installing and configuring plugins in PKHeX.Web.
Installing a Plug-in
PKHeX.Web uses the concept of "plug-in sources". Think of these as collections or repositories of plugins that can be installed in the tool. By default, PKHeX.Web ships with a source containing several core plugins: ALM (auto-legality mode), a set of Nuzlocke quick actions, and a fully integrated browser emulator.
To install a new plug-in:
-
Navigate to the "Manage Plug-Ins" page. You can access this from the left-hand menu:
-
On the Manage Plug-Ins page, available plugins will appear under the
Discoversection: -
Find the plug-in you wish to add and click the
Installbutton next to it. After installation, you will usually be forwarded directly to that plug-in's configuration page.

Once a plug-in is installed, you'll need to configure it. As mentioned, you might be redirected there automatically after installation. Alternatively, you can access the configuration page for any installed plug-in by selecting it from the left-hand menu:
When you open a plug-in's configuration page, you'll find settings specific to that particular plug-in. However, nearly all plug-ins will include at least these two common elements:
