Praxis MD vs HIPAASpace
HIPAASpace is the second-most-trafficked free NPI lookup site, known for offering a paid API alongside its web directory. Praxis MD is the newer alternative, built for daily B2B workflow with computed comparisons, change history, and no ads. Same NPPES data underneath.
TL;DR
HIPAASpace shines if you need a paid programmatic API for NPI lookups. Their web UI is ad-supported and the page-level detail is thinner than competitors.
Praxis MD is built for the people who lookup NPIs all day — credentialers, billers, recruiters. No ads, full schema, computed comparison stats, change history, and personalized Provyx funnel for users who eventually need bulk filtered exports.

When HIPAASpace is the right answer
You need a paid programmatic API and you're already vetted on HIPAASpace as a vendor. Their API has been around long enough to be integrated into many healthcare ops stacks.
When Praxis MD is the right answer
You use NPI lookups every day at scale and want a cleaner, faster directory. You need to disambiguate providers with peer comparisons and change history. You eventually want filtered CSV exports with verified contact data via Provyx. You don't need a paid API yet (we'll have one in v2).
