Praxis MD vs npidb.org
Both directories mirror the same CMS NPPES public dataset. The differences are what each site adds, what it leaves out, and how it treats your time. Here's the honest breakdown.
TL;DR
npidb.org has 8+ years of SEO authority and is the most recognized free NPI lookup site. It's ad-supported, the UI is dated, and the per-provider page stops at raw NPPES fields.
Praxis MD is the newer alternative built for daily B2B workflow use. No ads, full schema, computed comparison stats, change history from a delta log, and a freshness signal on every page. Same underlying CMS data.

When npidb.org is the right answer
You're doing a quick one-off lookup, you don't mind ads, and you want the most familiar interface. npidb.org has been around long enough that most credentialers have a muscle-memory bookmark for it.
When Praxis MD is the right answer
You use NPI lookups every day and the ad clutter slows you down. You need to disambiguate a provider with peer comparisons. You want change history to spot a provider who recently moved practice locations or added a subspecialty. You want every page to tell you exactly when its data was last refreshed. You eventually need bulk validation or a filtered CSV.
We're newer than npidb and we don't have 8 years of SEO authority. We've published this page because if you compared us side-by-side you should pick the right tool for the job — not the one that got there first.
