A sourc.dev entity page is not a review. There is no star rating, no editorial recommendation, no verdict. There is verified data — sourced, timestamped, and updated automatically — and there is context that helps you interpret it.
The header
The entity name, provider, domain, and quality grade are at the top. The quality grade — A through F — reflects how complete and fresh the data record is. An A-grade entity has all priority attributes verified within 90 days. An F-grade entity is a stub with minimal data.
The attribute table
Every row has four elements: the attribute name, the value, the verification date, and the source URL. Click the source URL — it links to the primary source that confirms the value.
If an attribute shows “Calibrating,” it means data has not yet been collected — not that the value is zero or unknown.
The version history
The version history shows every verified change to every attribute over time. The history is append-only — nothing is deleted.
The integration graph
The integration section shows which entities this entity connects to. Connections with a verified signal have a source URL.
Start here: Find an entity you use or are evaluating. Check its quality grade, then click one source URL in the attribute table to verify the data is what it claims to be.
