Host Your Own Private PaaS with Nixopus

Ever feel like you're jumping through hoops just to deploy a side project? You either commit to a full-blown cloud provider with complex configs, or you're manually SSH-ing into a VPS, running scripts, and hoping nothing breaks. It's a hassle that often kills the momentum of a good idea.

What if you could have your own simple, private Platform-as-a-Service (PaaS)? A place where you could deploy apps with a single command, but where you own the infrastructure and the bill? That's the itch Nixopus scratches.

What It Does

Nixopus is a self-hosted PaaS you run on your own server. Think of it as a minimalist, DIY version of Heroku or Railway. You give it access to your Git repositories, and it handles the build and deployment process for you. You define your app's setup—like environment variables and build commands—in a simple nixopus.yml file in your repo. When you push code, Nixopus sees the change, builds a container image using Nix (for reliable, reproducible builds), and runs it on your server with Docker.

Why It's Cool

The clever part is in the stack and the simplicity. It leverages Nix for the build stage. This means your builds are deterministic and repeatable, avoiding the classic "it worked on my machine" problem. The dependencies are locked down, leading to more reliable deployments.

It's also refreshingly focused. This isn't trying to be Kubernetes. It's a straightforward tool that automates the boring parts of deploying web apps (like APIs, static sites, or backend services) without locking you into a specific cloud vendor. You can run it on a $5 VPS, in your homelab, or on a beefy cloud instance. You control the data, the costs, and the specs.

For developers, the use case is perfect for personal projects, internal tools, prototypes, or small team applications where you want CI/CD-like automation without the complexity of managing a full pipeline.

How to Try It

Ready to spin up your own private deployment hub? The project is open source and the setup is documented.

1. Check the Repo: All the code and detailed instructions are on GitHub: github.com/raghavyuva/nixopus.
2. Prerequisites: You'll need a Linux server (or a local machine for testing) with Docker and Git installed.
3. Deploy Nixopus: The repo provides a docker-compose.yml file to get the Nixopus service itself up and running quickly.
4. Connect Your App: Add a nixopus.yml config file to your project, point Nixopus at your Git repo, and trigger your first deployment.
