Overview

Kite is a self-hosted email sending platform built on top of AWS SES. It provides the developer experience you'd expect from services like Resend or Postmark — a clean web dashboard, a simple REST API, and a template engine — without the recurring subscription costs. You bring your own AWS SES account and pay AWS directly.

Kite will be open-sourced soon.
