To quickly check if you are self-hosting a mParticle instance on your website, perform the following steps.
1. Open the Inspector by right clicking on your site and selecting "Inspect".
2. Navigate to the Network tab, and filter data by "Fetch/XHR" or "XHR".
3. Reload the webpage to trigger network events.
4. If you find a network call titled "config" to the jssdkcdns.mparticle.com domain, you are self-hosting mParticle and should look at the documentation here (Web SDK - Self Hosting Documentation) for enabling integrations.
The image below shows which Inspector settings to use to find any "config" network calls.
