PaaS vs VPS vs Serverless for Side Projects (2026)

You've built an app, and now it has to run somewhere other than your laptop. Your options come down to three models: rent a server (VPS/IaaS), hand your code to a platform (PaaS), or run functions on demand (serverless). Here's what each one means and how to choose.

PaaS in one sentence#

A Platform as a Service takes your source code and runs it: it builds it, starts it, puts HTTPS in front, restarts it when it crashes and keeps the machines underneath patched. You manage the app, and the platform manages everything below it.

That matches the standard definition from the U.S. National Institute of Standards and Technology: with PaaS, you deploy your own applications using the languages and tools the provider supports, and you don't manage the underlying servers, operating systems or storage (NIST SP 800-145, 2011).

With DockHosting, the whole workflow looks like this:

dock deploy
# → detects the stack, builds, starts the container, issues a certificate
# → https://myapp.dockhosting.cloud

The cloud stack: who manages what#

VPS / IaaS: a server of your own#

A VPS (virtual private server) is a Linux machine in a data center. It's maximum control and maximum responsibility: you install the runtime, configure nginx, set up Let's Encrypt, harden SSH, schedule backups and apply security updates.

Good for: custom system setups, unusual software, learning Linux, and very cost-sensitive workloads at scale. Watch out for: the work never ends. An unpatched server is a liability.

PaaS: ship code, not servers#

You connect a repo (or run a CLI command) and the platform does the rest. Modern platforms detect your framework, so there's no Dockerfile or Procfile to write, and they usually bundle managed databases so your app and data sit on the same private network.

Good for: web apps, APIs, bots, background workers, student projects, startups and agencies. Watch out for: less control of the OS. Pick a platform that supports Docker for the cases where you need it.

Serverless: functions per request#

Serverless platforms run your code only while a request is being handled. You pay per invocation, scale to zero automatically, and are limited in how long each run can last.

Good for: spiky traffic, webhooks, and frontends with a few API routes. Watch out for: time limits, cold starts and no long-lived connections. WebSockets, Discord bots and queue workers usually need a long-running process, so they fit a PaaS better. See hosting a Discord bot 24/7.

How to choose#

• "I want it live today and not think about servers." → PaaS.
• "It's a bot, worker or WebSocket server." → PaaS (always-on) or VPS.
• "It's mostly static with a few functions." → Static hosting or serverless.
• "I need root access or custom kernel modules." → VPS.

What a good PaaS includes in 2026#

• Git and CLI deploys with zero-downtime switches and rollbacks
• Automatic HTTPS on a free subdomain and on custom domains
• Managed databases with private networking and backups
• Logs you can tail from the terminal
• Docker support for the unusual cases
• Predictable pricing, ideally flat rather than metered

DockHosting checks those boxes, with a Free plan (an app plus a PostgreSQL database) and always-on apps from $4/month. Comparing platforms? Read our Heroku alternatives comparison, with every price checked in November 2026.
