DoubleZero

Open-source email API and infrastructure that lets developers own and control their email stack.

PlatformWebfreeglobal

An open-source, self-hostable email API and infrastructure platform that lets developers run and control their own transactional email stack. It addresses per-email billing and loss of infrastructure control by enabling teams and self-hosters to send and manage transactional email from a self-hosted setup, aimed at developers and startups rather than marketers seeking a no-code campaign tool.
