Why centron

The home for your open-source stacks

Open source promises digital independence – but this promise is only fulfilled on infrastructure that does what you want it to.

Everything can be installed

Root access and freedom to choose your distribution: whatever is available as a Linux package or container will run – from Nextcloud to Odoo.

Data really is with you

The cloud alternative only makes sense if the data is stored under national control – in this case, in German certified to ISO 27001 on the basis of IT-Grundschutz data centres.

Updates without the excitement

A snapshot taken before the update, with cBacks running in the background – even bold major upgrades remain reversible.

Community meets Support

The community provides support for the software, whilst centron offers 24/7 support for the infrastructure – together, they make a strong team.

Use cases

Optimal performance for GitLab, Nextcloud, Matomo & co.

Open source promises digital independence – on ccloud³ VMs, in Docker or in Kubernetes you run GitLab, Nextcloud, Matomo, Rocket.Chat or Ghost with full control and a transparent pricing structure.

Linux-based virtual machines

Linux hosting on ccloud³ VMs – ideal for open source software such as GitLab, Matomo or Nextcloud. High availability, secure infrastructure and a fair pricing structure with no hidden costs.

Simple Kubernetes

With centron Kubernetes you orchestrate open source container applications such as Nextcloud or Rocket.Chat automatically and efficiently. Scale flexibly, reduce administration and optimise your cloud costs.

Docker ccloud³ VM

Deploy open source applications such as Ghost, Matomo or GitLab CI/CD in Docker containers – with Docker Engine, docker-compose and fast scaling for developers and DevOps teams.

Managed WordPress hosting

For open source CMS such as WordPress, centron offers managed hosting with Premium Full Managing, daily backup and performance monitoring – perfect for agencies, freelancers and companies with high standards.

NodeJS ccloud³ VM

A NodeJS VM with NGINX, PM2 and NPM on Ubuntu or Debian – optimal for scalable REST APIs, real-time apps and open source applications with MongoDB support; runtime environments for web and mobile apps.

Databases and storage

You run PostgreSQL, MySQL, Redis and MongoDB on your own VMs – guides on database hosting; S3 Object Storage and block storage provide flexible storage solutions for open source applications.

Digital self-governance

Your own stack instead of ten subscriptions

Nextcloud replaces Drive, Matrix replaces messaging silos, and Vaultwarden replaces your password manager: whether on a suitably sized VM or distributed across a VPC, you can set up your own digital self-management system – for your family, club or business.

Hosting FAQ

Frequently asked questions

What is open source web hosting?

Open source web hosting, also known as open source hosting, refers to web hosting solutions based on open source software. Many of these technologies, such as Linux, WordPress or Docker, are regarded as powerful systems for developing modern web applications.

What is open source hosting at centron?

centron offers cloud hosting for open source with strong infrastructure, ISO certifications and a transparent pricing structure. Companies benefit from powerful Kubernetes hosting, Docker hosting and flexible Linux VMs.

What VM size do I need for Nextcloud & co.?

For small teams, a compact VM with 2 vCPU and 4 GB RAM is often enough; file storage grows flexibly via volumes. Start small with the €200 starting credit – you can scale up at any time without reinstalling.

How do I manage my web hosting?

Hosting at centron is managed via the user-friendly ccloud³ Console. It lets you deploy your application, manage your virtual servers and use integrated monitoring and security tools – complemented by API and CLI for automation.

What is a web hosting control panel?

A web hosting control panel is a web interface via which you manage your servers, websites and services. At centron you get access to a modern, in-house developed console – no complicated cPanels or WHMCS interfaces. If you prefer a classic panel, install it on your own VM: cPanel hosting.

How technical do I need to be?

centron has designed its console so that it can be used without in-depth technical knowledge. Whether you run a small website or manage a complex application – the console adapts to you; if you want to hand over operations entirely, choose a managed server.

What can I do from the console?

Provision and scale servers and resources, manage volumes and snapshots, configure cloud firewalls, set up backups with cBacks, view monitoring and control access rights – you install the databases and applications themselves with root access on your VM.

Does open source hosting at centron come with database management?

You run PostgreSQL, MySQL, Redis or MongoDB with root access directly on your ccloud³ VMs – on NVMe volumes with the IOPS databases need. Guides and architecture recommendations can be found on database hosting.

How much does it cost to get started?

The starting prices are deliberately low: ccloud³ VMs from €3.11 per month, volumes from €0.05 per GB per month and cBacks with no base fee. New accounts receive a €200 starting credit valid for 60 days – you can calculate the cost of your specific configuration transparently using the price calculator.

Do I need web hosting to contribute to open source projects?

Not necessarily. For purely contributing to open source code via platforms such as GitHub you do not need hosting. However, if you want to publish or host your own open source application, open source hosting becomes the basis of your deployment.

What are Linux systems?

Linux is an open source operating system characterised by stability, security and efficiency. At centron we rely on Linux hosting with our powerful ccloud³ VMs.

Can I rent a server for my open source project?

Yes. You can rent managed servers or cloud servers especially suited to open source hosting. Thanks to scalability and monitoring, you always retain control of your project.

Which cloud hosting options does centron offer?

Whether virtual machines, Kubernetes clusters or dedicated root servers – at centron you will find cloud hosting for open source projects with maximum freedom, performance and developer-friendliness.

Which storage solutions does centron offer?

With S3 Object Storage and block storage, centron offers flexible storage solutions for open source applications.

Can this be implemented in a way that complies with the GDPR?

Yes. Self-hosted open source is usually the clean option in data protection terms: there is no provider processing data for its own purposes. At centron, the infrastructure underneath is also located in Germany. Operations take place in data centres certified to ISO 27001 based on IT-Grundschutz; for ccloud³ / Managed Cloud there is an unqualified BSI C5:2020 Type 1 attestation. Details can be found in the Trust Center.
