ARLONG
CERTIFIED.
A transparent registry of publishers that meet our published reputation criteria, drawn from a public research dataset.

A traceable source.
2085 qualifying domains. Each listing comes from the same reproducible rule: high or very high factual reporting, together with high credibility. No hand-picked additions.
Certified here means dataset-qualified publisher reputation. It does not mean every article is true, or that a website has passed an independent security audit. Pages admitted through the origin fast path are explicitly marked “screening skipped.”
Every qualification
has a paper trail.
Dataset: Idiap / Media Bias Fact Check research data ↗
Snapshot commit: 2025-05-26. Individual rating observation dates are not supplied. The registry reflects that snapshot rather than a fresh assessment.
Exact HTTPS hostnames and their www aliases qualify. Other subdomains, user-submitted text and pages fetched through an unverified intermediary remain screened. Access challenges and failed downloads still fail.
Upstream repository license: Apache 2.0. Ratings originate from Media Bias/Fact Check. Arlong applies the qualification policy; the dataset authors do not endorse this product.
