Live internet-censorship measurements across 215 countries

AUTH NONECORS ✓AGENT ✓HTTPS ✓COMMERCIAL ✓

Voidly aggregates network measurements into a live picture of internet censorship: which domains are blocked, where, and how deeply. The keyless /v1/measurement/summary gives a one-call global snapshot, while /data/censorship-index.json ships the full ranked dataset with Schema.org markup. The index is published under CC BY 4.0, so credit Voidly if you use it.
