Is it practical to host several small projects on one VPS?

Yes, it can work very well for small projects and is often cheaper and easier to manage than several separate platforms. The main tradeoff is that one server becomes a shared point of failure, so don’t expect perfect uptime. Keep regular backups somewhere outside the VPS, such as object storage, and make sure you can restore them.

There are plenty of inexpensive providers, so compare location, bandwidth, storage, backup options, and support rather than focusing only on the monthly price. A basic Linux VPS should be sufficient for lightweight applications. Tools such as a control panel or a simple SSH-based deployment workflow can help, but Kubernetes or k3s is probably unnecessary unless you specifically want to learn it or expect to add multiple machines later.

A single VPS is a reasonable setup, but isolate the applications from one another. Containers with Docker Compose are usually enough for a few small services, along with a reverse proxy for routing different domains. Keep the operating system and dependencies updated, limit exposed ports, and monitor disk space and memory. If one project becomes important or resource-heavy, move it to its own host later.
