Listmonk
Self-hosted email newsletter and mailing-list manager comparable to Mailchimp, written in Go with a single binary plus Postgres. Regarded as one of the cleanest-designed apps in this space.

⚙ Full Stack
Go backend compiled to a single binary, Vue.js admin frontend embedded in the binary, Postgres as the sole datastore including full-text search via native Postgres features.
📈 Scaling Analysis
The single-binary design and Postgres-only persistence make this trivially horizontally scalable behind a load balancer for the web/API tier; the main bottleneck at real scale is SMTP relay throughput, which is outside the app's control.
🚀 Running on Nexlayer
One app pod and one postgres pod is the entire footprint; point the DB config at postgres.pod:5432 and set the public root_url to the Nexlayer domain for correct unsubscribe/tracking links. mirror.gcr.io/library/postgres covers the DB image cleanly with no other dependencies.
