Atlas FDA vs AccessGUDID

An honest comparison, including where AccessGUDID is the better choice.

What AccessGUDID is

NIH device identifier registry. Complementary rather than competing: it covers UDI, not clearance decisions.

Where Atlas FDA differs

• Linked, not siloed. Manufacturers, product codes and specialties are browsable pages.
• Built for machines. A documented JSON API, MCP server, and bulk export.
• Change alerts. Get told when a competitor clears a device.

When to use AccessGUDID instead

For anything of regulatory or legal consequence, use the primary source. AccessGUDID is authoritative; Atlas FDA is a convenience layer over the same public data.
