Bastian for WordPress.

The official plugin puts Bastian on your WordPress site without touching a line of code. Download it below, upload it to your site, and paste in your license key — the whole thing takes about two minutes.

Installation

From download to first conversation.

  1. 1

    Download the plugin

    Use the button above. You'll get a small zip file — leave it zipped, WordPress wants it that way.

  2. 2

    Upload it to WordPress

    In your WordPress admin, go to Plugins → Add New Plugin → Upload Plugin, choose the zip, then click Install Now and Activate.

  3. 3

    Paste your license key

    Grab your key from your Bastian dashboard (a free tier is available), paste it into Settings → Bastian Assistant, and save. The chat widget appears on your site right away.

Before You Install

What the plugin needs.

WordPress 6.0 or newer
Tested up to WordPress 7.1. If your site is a few versions behind, updating first is a good idea anyway.
PHP 7.4 or newer
Most hosts are well past this. If you're not sure, your hosting dashboard will say — or the plugin will tell you on activation.
A Bastian license key
The plugin is the connector; Bastian himself runs on our servers, protected by PsiGuard. Sign up free at heybastian.com and your key is waiting in your dashboard.
Common Questions

The things people ask first.

Will this slow my site down?

No. The plugin is three small files, and all the heavy lifting happens on Bastian's servers — nothing runs on yours except a lightweight widget.

How do I update the plugin?

For now, download the newest version from this page and upload it the same way — WordPress recognizes it as an update and keeps all your settings. Once Bastian is listed in the WordPress plugin directory, updates will arrive automatically like your other plugins.

Can I control where the widget shows up?

Yes — hide it for logged-in users, or exclude specific pages and posts, right from the plugin's settings. The widget's look, greeting, and knowledge live in your Bastian dashboard.

Not on WordPress?

Bastian works anywhere you can paste a snippet of code. Install the web widget →
