Deep Dive: Switching from Fly.io to Dokploy
Trade-offs, installation & data architecture
What you trade away
Dokploy brings apps, databases, previews, and backups to your own servers, but global placement, Anycast networking, and provider-managed capacity are not included.
How to deploy Dokploy
Dokploy Cloud signup or one-line install script on a Linux VPS
What it takes to run
A VPS with at least 2 GB RAM, free ports 80/443/3000, DNS, and ongoing Docker/server administration
Where your data lives
Dokploy metadata is stored in PostgreSQL; application and database data lives in Docker named volumes or bind mounts on the deployment servers, with optional S3 backups
Why fork Dokploy instead of vibe-coding a Fly.io clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Fly.io, deploy one container on a self-owned host and expose operational limits clearly. The hard boundary is global edge compute, anycast networking, orchestration, volumes, and platform operations, plus infrastructure scale, operations, and reliability.
