OpenProspector: open-source Clay alternative. Find and enrich B2B leads on your own provider keys.

In simple English

Commercial lead-finding tools charge a heavy fee for every contact they sell. This software lets you connect your own provider accounts directly. You pay the wholesale price for emails and phone numbers instead of paying a middleman. The program tests multiple services in order until it finds valid contact details. You keep your data in your own database and avoid paying twice for people you already checked.

What it is

An open-source program that runs lead generation and contact enrichment waterfalls using your own API keys. It stores records in a local SQLite database and provides a web interface built with React.

What it is good for

Solo founders and sales teams who need to find thousands of B2B contacts each month and want to cut their data costs by skipping third-party SaaS markups.
