Live · Beijing node · refreshed weekly
Which parts of your stack break first in China.
An open lab that measures how foreign web-stack dependencies behave for real users in mainland China — one dependency per page, whole platforms end to end, every verdict reproduced from a Beijing node.
What this lab does
Test, verify, produce.
Test
Single dependencies — fonts, auth, analytics, media, payments — each loaded the way a real product loads it, plus whole platforms like Firebase, Netlify, and Vercel.
Verify
Every verdict comes from an Alibaba Cloud Beijing node: curl + dig for reachability, Playwright for what a real browser shows. Not a VPN. Not a guess.
Produce
Weekly machine-readable evidence — verdicts, latency, screenshots, downloadable run reports — accumulated as an open data asset since June 2026.
