vs Docker & Kubernetes
Why Prongo
Compared, honestly
The same three-service app in the tools you already know, and where each one genuinely wins. No tool is bad here. They solve different problems.
vs Docker & Kubernetes
Docker Compose is wonderful for local development and fine on a single VPS, until you need zero-downtime deploys or a second machine. Kubernetes solves all of that and adds a full-time job to your calendar. Prongo sits between them: Kubernetes reliability, Compose-level effort.

✓ No label selectors that silently mismatch
✓ No image registry, Prongo builds from your Dockerfile
✓ Service discovery built in, no DNS plugins needed
✓ Deploy order resolved automatically from depends_on
The same three services need 8+ Kubernetes manifests (~150 lines) against one 18-line prongo.yaml. What that single file saves you:
✓ No Deployments, Services, Ingress, or Secrets manifests
✓ No label selectors that silently mismatch
✓ No image registry, Prongo builds from your Dockerfile
✓ Service discovery built in, no DNS plugins needed
✓ Deploy order resolved automatically from depends_on

Prongo still runs on Kubernetes under the hood, so you get the reliability without ever writing a manifest. The complexity does not disappear; it moves out of your repo.
vs Vercel & Netlify
For a static site or a single Next.js app, Vercel and Netlify are genuinely great and you should probably use them. The gap appears when your repo is more than a frontend: an API with its own runtime, a database, a worker chewing through a queue. On a frontend platform each of those becomes a separate product, a separate deploy, and a separate bill. On Prongo they are three more lines in the same file.
A static site or one Next.js app
Excellent
Works fine
A backend API with its own runtime
Serverless functions only
Any container, long-running
A database next to your app
External add-on, extra bill
One more service in the yaml
Background workers and queues
Not their model
A service like any other
The whole monorepo in one deploy
One app per project
The repo is the unit
Cost when you outgrow the free tier
Per-seat and per-usage, adds up
Free beta, fair plans later
