What’s a simple managed way to host a Docker container for a side project?

I'm working on a small side project and want to deploy an existing Docker image without managing a VPS, server security, updates, and networking myself. I don't need unlimited scaling, edge runtimes, or a platform-specific framework. Ideally, I'd pay around $5–$10 per month, provide a Dockerfile or image, and have the service run it with minimal configuration and reasonable portability. What hosting options fit that use case?

Fly.io could be a good fit. It’s usage-based, and a small instance can cost around $5 per month or less, especially if you allow it to stop when idle. Deployment can be as simple as providing a Dockerfile and a small configuration file, without rewriting your application for a special framework.

You could rent an inexpensive VPS and install a self-hosting control panel such as Coolify. It gives you a more convenient deployment interface for Docker applications and handles some of the setup, but it doesn’t eliminate server maintenance completely. A low-cost VPS provider such as Hetzner can make this approach affordable.

A basic VPS with Docker preinstalled is another option, although you would still be responsible for updates, firewall rules, backups, and general server security. Managed VPS plans from providers such as DigitalOcean may be closer to $10–$15 per month rather than the lower end of your budget.

Railway, Heroku, and Fly.io all support fairly direct container deployments. They handle most of the infrastructure for you while letting you keep your application packaged as a normal Docker image. Fly.io in particular has a straightforward command-line setup for small projects.
