The Self-Hosting Stack That Works

Infrastructure: Coolify (deploy anything)

Database: Supabase or self-hosted PostgreSQL

Storage: S3-compatible (MinIO or Backblaze B2)

Analytics: Plausible or Umami

Monitoring: Grafana + Prometheus

Chat: Mattermost

Docs: Outline or Bookstack

When to Choose Open Source

Choose open source if:

• You have technical skills to maintain it

• You need full control of your data

• Privacy is critical

• You want to save money at scale

Choose managed services if:

• You value time over money

• You don't have DevOps capacity

• You need enterprise support

The Bottom Line

Open-source alternatives can save thousands per year. But they cost time to maintain.

The calculation: Your hourly rate × hours of maintenance vs monthly SaaS cost.

At scale, self-hosting almost always wins economically. For small teams or individuals, managed services may be better value.
