## Web Technologies

ByteDance's homepage made 40 requests to 5 domains, and 1 service 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.

1 third party by category: Unclassified 1 (Lark). 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 (1)

- Lark: 15 requests to feishucdn.com
