opensend.cc

Run an open-source email API and dashboard on your own server

Meet opensend.cc

opensend.cc is an open-source email service that developers deploy on their own infrastructure. It provides a Resend-compatible API, a dashboard, and delivery through AWS SES or an SMTP relay. Teams can manage sending domains, scoped API keys, message logs, and suppression records from the same installation.

The service includes React-based templates, audience lists, broadcasts, signed webhooks, and a test mode that accepts requests without delivering messages. Its setup uses Docker Compose with a self-hosted database and authentication components. Operators remain responsible for the server, sending-provider costs, DNS configuration, and deliverability. The self-hosted project is available under Apache 2.0, while a separate hosted edition has a waitlist. Existing SDK compatibility should be checked against the API features an application uses.
