## Web Technologies

Discourse's homepage made 96 requests to 13 domains, and 3 services controlled by another company. Loaded on 2026-11-04 by a browser that accepted nothing; other visits may load more or less. What a page loads is not a list of who receives customer data.

3 third parties by category: Analytics 1 (Google Cloud); Marketing automation 1 (HubSpot); Development 1 (reviewed: GitHub). Each company that appears controlled by another organization is counted once, under the main category of the technologies detected from it on this homepage or, when none was, the category recorded from the company's own page (marked reviewed) or else the one it is usually detected as on other published homepages (marked as such); unclassified: none of these.

### Third parties (3)

- HubSpot: 14 requests to hsforms.com, hs-banner.com, hscollectedforms.net, hubspot.com, hs-analytics.net, hs-scripts.com, hsadspixel.net, hsforms.net; HubSpot
- Google Cloud: 6 requests to googletagmanager.com, googlesyndication.com, google-analytics.com; Google Analytics, Google Tag Manager (its subprocessor list names it too)
- GitHub: 1 request to github.com

### First party (1)

- Discourse: 75 requests to discourse.org; Amazon CloudFront, Amazon S3, Amazon Web Services, GSAP 3.14.2, HSTS, HTTP/3, HubSpot Cookie Policy Banner, Jekyll 4.4.1, Lucide, Open Graph, Plausible, Priority Hints, Ruby

2 tracked companies loaded by the homepage are not in Discourse's subprocessor list. A website can use a service without it processing customer data.
