Baiduspider
The crawler behind Baidu Search. Notably weaker JS rendering than Google or Bing — dynamic rendering is still recommended by Baidu itself for SPA-heavy sites.

- Our v1 audit found baidu.com itself serves declared bot UAs a fully pre-rendered ~250 KB HTML while Chrome receives a 357-character shell. Textbook dynamic rendering at the world's fourth-largest search engine.
- Sibling spiders for images, video, news, favorites — each with its own UA token.
- No publicly enumerable IP-range JSON. Reverse-DNS to *.baidu.com is the standard check.
