Healthchecks
A cron-job and scheduled-task monitoring service using the dead-man's-switch pattern. Standout trait is its clean Django architecture and mature multi-channel alerting.

⚙ Full Stack
Django application backed by Postgres (or MySQL/SQLite), with a Huey/Celery-style background task runner for sending alerts via email, Slack, webhooks, etc. Stateless web tier behind the DB.
📈 Scaling Analysis
Scales well horizontally since the web tier is stateless Django behind Postgres — add more web replicas behind a load balancer with no code changes. The main bottleneck at very high scale is ping-ingestion write volume on the single Postgres instance.
🚀 Running on Nexlayer
Two pods: a Django web pod and a postgres pod (postgres.pod:5432); set SITE_ROOT/ALLOWED_HOSTS from env rather than hardcoding since Nexlayer assigns the URL. Mirror the Python base image via mirror.gcr.io.
