The cheap Clay & Apollo alternative
Clay charges $495/mo for API pass-through. Run it yourself for pennies.
OpenEnrich turns a list of names and domains into verified emails, titles and company data. A free local engine resolves what it can at zero cost, then unresolved rows fall through a waterfall of data providers on your own API keys, about $0.01 per verified lead. Your AI agent runs the whole thing over MCP.
AGPL-3.0. Self-hosting stays free forever. No credits, no seats, no re-billing.
The math
Enrichment tools resell the same wholesale data APIs at a 50 to 500x markup. OpenEnrich is the engine without the markup: you pay the data vendors directly.
