OpenGTM vs. Clay
OpenGTM is an open-source, self-hosted alternative to Clay for teams that want programmable lead sourcing, enrichment waterfalls, AI research, and outbound workflows while retaining control of infrastructure, data, and keys.
The short answer
Section titled “The short answer”Choose OpenGTM when self-hosting, BYOK provider access, auditable cell provenance, API access, and explicit spend ceilings matter more than a fully managed service. Choose a managed platform when you prefer vendor-operated infrastructure, bundled data credits, and a larger polished integration catalog.
