What Does 'Hello World' Actually Cost on AWS vs Bare Metal? (2026)

· 10 min read

Short answer: one "hello world" container with a domain and HTTPS costs about $32 per month on AWS if you set it up carefully, and about $69 per month if you follow the default AWS tutorial. The same thing on a small Hetzner Cloud server costs €5.99 per month. Bare metal is the surprising one. A Hetzner AX42-1 costs €97.30 per month, which makes it the most expensive option here, not the cheapest.

Two results are worth explaining, and neither is what people usually say:

  1. Compute is not the expensive part on AWS at this size. In the realistic setup, the container is 15% of the bill. The other 85% is the load balancer and the NAT gateway. Those cost the same whether you serve one request per month or a million.
  2. Bare metal is not cheap. It is cheap per app. A dedicated server only pays off when you fill it. For one container it is a bad deal.

Render vs Railway vs Fly.io: Pricing Compared and When Each Wins (2026)

· 7 min read

Short answer first: the three platforms charge in three different shapes. Render adds a workspace fee for teams on top of fixed instance prices. Railway has no free tier and meters everything per second on top of a small plan fee. Fly.io is pure pay-as-you-go per second, with no base plan fee at all. The right pick depends less on the headline price and more on which of those shapes fits how you work.

This post explains each model, shows a side-by-side table, and gives the cases where each one wins.

Self-Host Postgres or Use Supabase? Here's How to Decide

· 6 min read

Short answer first: use Supabase if you want Postgres plus auth, realtime, storage, and a dashboard as one managed bundle. Self-host Postgres – or use a managed Postgres – if you mostly need a database and your app already handles its own auth and logic. The choice is not really "Postgres vs Supabase". It's whether you need the extra layers Supabase puts on top of Postgres.

This post gives you a clear way to decide, a side-by-side table, and the cases where each option is the right one.

Usage-Based Pricing: Why Your Railway and Render Bills Creep Up

· 5 min read

Usage-based pricing always looks cheap on the signup page. "Pay only for what you use." "Starts at $5." Then a few months in, your bill is double what you guessed, and you can't really point at the one thing that did it.

I've been comparing platforms a lot lately – partly because I run one, partly because people keep emailing me to ask whether X or Y is cheaper than Hostim. So here's the actual math on why metered hosting drifts upward over time, and the honest version of when it's the better deal anyway.

Let's Encrypt Wildcard Certs in Kubernetes: cert-manager + DNS-01 (and When We Skipped It)

· 7 min read

If you run Kubernetes and want a wildcard TLS cert from Let's Encrypt — say *.example.com — you need a DNS-01 challenge. HTTP-01 cannot prove control over a wildcard. That single fact rules out the easy path most tutorials show.

This post is what we actually run at Hostim.dev for our shared *.region.hostim.dev wildcard. We use cert-manager for per-app certs and a plain certbot Ansible playbook for the wildcard. Two different tools for two different jobs. We will explain why, then show the code for both.

Which Database Should You Self-Host? SQLite vs MySQL vs PostgreSQL vs Redis

· 6 min read

When you're deploying your own app, the database choice matters more than most people think. It affects performance, ops complexity, backups, and how much memory your server needs.

There are four options you'll run into most often: SQLite, MySQL, PostgreSQL, and Redis. They're not all the same kind of database – and that's the point. Here's when each one makes sense.
