Why we picked it
For agencies reselling voice agents, Synthflow's white-label and account-management features beat the dev-first alternatives. Operators don't need to learn an API.
Overview
Synthflow is a no-code platform for building voice agents — drag-and-drop flows, prebuilt templates, and white-label for agencies. It targets the gap between developer-first tools like Retell and full enterprise platforms, so most users are operators or agencies shipping voice agents for clients without code. Plans scale by minutes and seats.
