I write JS, sometimes Rust & Go, I also build stuff at @techulus

So why am I building a PaaS (platform as a service)?

Short answer: It's because I love @Railway and I want the same experience with my own servers.

Long answer: I self-host several services on my home lab servers. This was a very manual task with minimal automation; I pulled code into servers, set up Docker Compose files, Tailscale, Traefik, DNS, pretty much everything was manual. On the other hand, when I deploy my side projects to services like Railway or @vercel, everything is just a few clicks away and feels magical. I want to bring this seamless experience to my infrastructure.

In case you're wondering, yes, I've tried @coolifyio / @getdokploy / @dokku / @portainerio and some other self-hosted PaaS solutions, but they didn't work well for me. There were some flaws that I couldn't fix (private networking, load balancing workloads across servers, ease of swapping servers, self-healing workloads etc.).

So I started to rethink how I could build the perfect self-hosted PaaS. FYI, it's heavily inspired by platforms like Railway, https://t.co/yy2vnoQ741, etc. My research was mostly reading their engineering blogs and chatting with LLMs.

Here's how my solution differs:

> Coolify/Dokploy = centralised control which is SSH-driven, push-based orchestration, not multiple server native.
> What I'm building = a distributed peer-to-peer container fabric: agent-driven, pull-based orchestration, private-first networking, disposable workloads, proxy nodes to handle ingress, and finally, a touch of magic.

@pierrecomputer who is going to review it now

What happened to @Railway CDN? I don't see it anymore

[Arjun @arjunz]

Off to a productive weekend:
- migrated capture database from @Railway to @PlanetScale , those NVMe drives are fast 🏎️
- setup failover instances in GCP
- testing failover load balancing with @Cloudflare

[Arjun @arjunz]

@ngeloxyz Railway has been amazing over the past years and I’ll continue to run most of my workloads at Railway.

One change after this incident, I’ve setup failover instances in other cloud providers so that in case something like this happens again, we can handle it gracefully.

[Arjun @arjunz]

@prateek_0041 Great for 2 months, you won’t remember it after that.

2026 is the year of broken software

[Arjun @arjunz]

My plan, multi cloud with cloudflare LB
- move db to @PlanetScale
- replicate services in Railway and GCP (cloud run)
- put a cloudflare load balancer at edge
- health check and load balance, Railway will be main, fallback to GCP when needed

I don’t have any stateful services other than database

[Arjun @arjunz]

@pugson edge is down, services are running

[Arjun @arjunz]

@JustJake any ETA on service recovery?

[Arjun @arjunz]

@Railway Services seems to be affected

[Arjun @arjunz]

@thekitze Too bloated, I want probably 10% of what you’re building
