I Replaced My SaaS Stack with Self-Hosted Tools - Monthly Bill: $347 to $12

My SaaS bill was $347/month. Now it is $12 (just electricity). Here is every Docker config included.

The Stack

  • Notion ($10) -> AppFlowy
  • Vercel ($20) -> Coolify
  • Datadog ($23/host) -> Grafana + Loki
  • Railway ($20) -> Coolify
  • Resend ($20) -> Listmonk
  • PostHog ($30) -> Plausible Analytics
  • Various ($224) -> Self-hosted

Hardware

Beelink Mini PC -- Intel N100, 16GB RAM, 500GB SSD. $150 one-time.

1. AppFlowy replaces Notion 

services:
  appflowy:
    image: appflowyio/appflowy_cloud:latest
    ports: ["8000:8000"]
    volumes: [appflowy_data:/data]
Enter fullscreen mode Exit fullscreen mode

Docs, databases, kanban. Offline-first. AI built in.

2. Coolify replaces Vercel + Railway 

curl -fsSL https://cdn.coollify.io/install.sh | bash
Enter fullscreen mode Exit fullscreen mode

Deploy from Git, automatic SSL, Docker-native.

3. Grafana + Loki replaces Datadog

  grafana:
    image: grafana/grafana
    ports: ["3000:3000"]
  loki:

    ports: ["3100:3100"]
  prometheus:

    ports: ["8001:8000"]
    environment:
      - BASE_URL=https://analytics.yourdomain.com

  listmonk:
    image: listmonk/listmonk:latest

6. Uptime Kuma replaces Better Uptime

  uptime:
    image: louislam/uptime-kuma:1
    ports: ["3001:3001"]
    volumes: [uptime_data:/app/data]
Enter fullscreen mode Exit fullscreen mode

Beautiful status pages. Alert integrations.

Full Docker Compose

    ports: ["80:80", "443:443", "81:81"]
