Open-source email finder and lead discovery — free alternative to Hunter.io and Apollo.io.

Cost	$34–$399/mo	$49–$149/mo	Free forever

Accuracy

ColdReach finds fewer emails than paid tools that have years of indexed data. Expected accuracy is 50–70% vs 85–90% for Hunter.io. But it's free, private, and you own everything.
