W4OS is a WordPress plugin for OpenSimulator grid management. It allows users to register for an avatar and choose a starting outfit. It also provides useful blocks that can be displayed on any page, sidebars, headers and footer (via shortcodes, widgets or Gutenberg blocks).

It is pretty easy to set up, so you can start accepting new users within minutes.

The project is sponsored and developed by Speculoos World and Magiiic.

At the time of writing, this plugin represents around 6000 lines of code, 750 commits, hundreds of hours and dozens of sleepless nights

Good news: you can buy us a coffee (or a coffee machine) to support all this hard work. Just follow this link:

    When setting up w4os on a new site, we had trouble finding out why the search was not working with the internal search engine. However, it worked perfectly well using an external engine running exactly the same versions of the libraries. And it works perfectly internally on several public grids that I manage, as well……


With the most recent improvements and features. Something close to the next stable release, but there might be some bugs left.


The current development, unstable version. Really don’t use it in production environment. It might (and does probably) contain bugs or work in progress.
