I’v built a platform for email, text, and phone calls through one API and replaced all my subscriptions with Resend, Twilio, …

I built an opensource communications platform for AI agents and regular backends.

The idea: your SaaS or your AI agent calls someone to confirm an appointment, texts them the details, or sends a signup email.

All through one API or MCP connection.

I’ve just shipped version 0.23.0 focused on email:

– tracking delivery and email opens while avoiding ad blockers.

– easier custom-domain setup that auto-detects DNS provider.

– full support for React Email templates.

Think Resend-style email functionality, alongside SMS and real phone calls for agents.

I'm now using it in all my projects in production and getting close to 100$ in revenue from complete strangers from the internet buying usage credits!!

It’s available hosted or self-hostable under AGPLv3, while self-hosting requires external providers for the communication channels you use, but the docs has all instructions needed for that.
