Docker hosting in the EU, without a server to look after

blitz.cloud is Docker hosting on servers in the EU, run by BlitzWorks, a German company. You name an image from Docker Hub or connect a GitHub repository with a Dockerfile, and a few minutes later your container answers on an HTTPS address. You don't rent or maintain a server for it. Starting costs nothing and needs no credit card: the free plan runs with no end date in Europe (EU, EEA, UK, Switzerland) and for 7 days elsewhere. A container that has to answer at any hour costs from 3 EUR a month.

What you get

• An HTTPS address for every container, like api.lena.prod.page. The certificate is issued and renewed for you.
• blitz.cloud finds the port itself, from the EXPOSE in your image.
• Managed databases: PostgreSQL, MariaDB or Redis, connected to the container and backed up every night.
• Folders your image declares as volumes survive restarts.
• Environment variables are stored encrypted, up to 64 per app.
• If your tag follows new releases, like latest, the new version arrives overnight. If it doesn't start, the old one keeps running.
• The app's page says in one sentence how it is doing and shows the last lines it printed.

Online in three steps

1. Create an account with e-mail, GitHub or Google. You pick an address like lena.prod.page on the way.
2. Name the image. The wizard searches Docker Hub as you type. For ghcr.io or Quay, enter the full name, such as ghcr.io/owner/image. If your code is on GitHub, connect the repository instead and blitz.cloud builds your Dockerfile on every push.
3. Click "Put it online". The page shows each step as it happens and ends with a link to open and share.

The long version with every screen is the guide How to deploy a Docker container for free. Ports, volumes and updates are covered in the docs under Deploy a Docker image.

What Docker hosting costs here

Prices are fixed per month and include VAT. Nothing is billed by runtime, requests or traffic.

If it isn't for you, ask within 30 days of your first payment and you get the first month back. Monthly plans end any month. Every number is on the pricing page.

Servers in the EU, run by a German company

blitz.cloud is built and run by BlitzWorks UG (haftungsbeschränkt) in Regensburg, Germany. Your containers, their files and databases sit in data centres at three locations in the EU, and backups go to separate storage, also in the EU. We rent and operate the servers ourselves, with no US cloud provider underneath.

You can download the data processing agreement (DPA) as a PDF once you are signed in, on any plan. Invoices carry your VAT ID if you enter it when paying.

The rest belongs here too: requests to your address pass through Cloudflare, our e-mails are sent by Google Workspace, and Claude from Anthropic helps work out what an image needs. What each of them gets to see is listed line by line on Data location and GDPR.

How your container is fenced in

Every app runs in its own sandbox. An image that starts as root runs as root inside that sandbox and nowhere else. Network rules block everything first: your container reaches neither other accounts nor the platform's internal services. Databases have no public address, and only your own apps can reach them.

The status page shows whether everything is up. It lives outside the platform, so it answers even when the platform doesn't.

Docker hosting or a Docker server of your own?

A rented server with Docker is what most people weigh first. It gives you full control, and it gives you work: updating the operating system, setting up a reverse proxy and certificates, keeping a firewall, building and testing backups, and finding out at night why the container stopped.

If you enjoy looking after the server, you don't need us. If you want the app online and your evenings for the app, this is the place. The longer comparison is blitz.cloud or your own VPS, and other European platforms are in EU PaaS alternatives.

What people host here

Most containers are people's own projects: a Node.js API, a Python script that runs around the clock, a Discord bot or a web app with PostgreSQL. Then there are ready-made images like n8n, Uptime Kuma or Vaultwarden. For those there is the App Store, where port, database and folders are already right.

When blitz.cloud is the wrong choice

Better to read it now than after signing up:

• Private images from a registry don't work yet. Private code does: connect your GitHub account and we build private repositories too.
• The servers are amd64. An arm64-only image won't start, so build with --platform linux/amd64.
• There are no GPUs and no servers outside the EU.
• The platform left beta on 26 September 2026, so its history is short. What runs today and what is missing is on What's live.

Docker hosting questions

What does Docker hosting cost on blitz.cloud?

The free plan costs nothing and runs with no end date in Europe (EU, EEA, UK, Switzerland) and for 7 days elsewhere. A container that stays awake at any hour costs 3 EUR a month as a Pro app with 512 MB of memory, or 5 EUR with 1 GB. Pro for the whole account is 7 EUR a month. Prices include VAT, and traffic is not billed.

Can I host a Docker container for free?

Yes, on the free plan, without a credit card, with no end date in Europe (EU, EEA, UK, Switzerland) and for 7 days elsewhere. It has room for up to 5 apps sharing 512 MB of memory. A free container goes to sleep after 15 minutes without a visit and wakes when somebody opens it in a browser. Webhooks and API calls don't wake it, which is what the Pro app is for.

Where are the servers?

In data centres at three locations in the European Union. blitz.cloud is run by BlitzWorks UG (haftungsbeschränkt), a company in Regensburg, Germany. The platform picks where an app runs; you can't choose a region yet.

Can I use this Docker hosting under the GDPR?

blitz.cloud is run by a German company, keeps apps and data in the EU and uses no US cloud provider for hosting. The data processing agreement comes with every plan. The page on data location and GDPR lists every service involved, including Cloudflare on the way to your app. Whether that is enough for your case is your data protection officer's call, not our sales page's.

Can I use Docker Compose?

Yes, through GitHub. If the repository has a Compose file with a web frontend, an API and a worker, the wizard reads it and suggests the parts. They go online as one app with one address. Databases in the Compose file are replaced by a managed database. Each part that runs all the time counts as one of your plan's apps.

Can I host private Docker images?

Not private images from Docker Hub or another registry, not yet. Private GitHub repositories work: connect your GitHub account and blitz.cloud builds the Dockerfile in the repository and puts every push online. The built image is kept in our own registry in the EU.

Do I need to know Kubernetes or server administration?

No. You need an image that speaks HTTP on a port. The platform handles certificates, routing, restarts and backups, and you never open a terminal for it.

Can I use my own domain?

Yes, with a Pro app or with Pro. You connect a domain you own on the Domains page in three steps, and HTTPS is set up for it. On the free plan every container runs under a subdomain of your address.

Can my container offer ports other than HTTP?

Visitors reach a container over HTTPS. Plain TCP ports, for MQTT for example, come with Pro as an experimental feature, described under TCP ports in the docs.

How do I get help when a container won't start?

The app's page says in one sentence what is wrong and shows the last lines of output. If that isn't enough, click "Give feedback" in the dashboard or write to hallo@blitzworks.io. We read every message and answer by e-mail.
