Best Free Clearbit Alternatives in 2026

Replace sunsetted standalone Clearbit plans and costly HubSpot enterprise contracts with free B2B company registries, logo extractors, and domain intelligence APIs.

Clearbit (HubSpot Breeze) Friction:

Discontinuation of standalone developer plans post-HubSpot acquisition, deprecation of free endpoints, and mandatory high-ticket annual CRM contracts.

The FreeAPI Advantage:

Free B2B company & filing data (Shodan EntityDB, GlobalEntity, Funding Signals), email intelligence (Hunter, EmailRep), and zero-auth ICANN RDAP.
