We are SaaS Web
Open-source solutions that drive businesses and agencies forward.
We plan, host, and develop digital applications – performant, secure, and without vendor lock-in, meaning without tying you to a single provider. For reliable websites, portals, and platforms in daily use.

Who we are
A digital agency from Karlsruhe
Since 2009, we have been developing and operating websites and web applications for companies, agencies, associations, and public institutions – from WordPress websites to specialized applications for municipalities. You can find our managed open-source applications on saasweb.cloud.
The minds behind it
Owner-managed since 2009
SaaS Web has been owner-managed since its founding. The management team works directly on projects – so when you talk to us, you’re speaking with people who can make decisions and know exactly what they’re talking about.

Matthias Wulkow
Founder and Managing Director
Strategy, Conception, Customer Projects
Matthias founded SaaS Web in 2009. He translates requirements into viable concepts, leads customer projects from the initial idea to go-live, and remains your contact person afterward.
Good technology goes unnoticed. Bad technology is noticed every day.

Daniel Jagszent
Technical Managing Director
Architecture, Development, Operations
Daniel is responsible for technology: architecture, development, and the operation of our servers and platforms. He ensures that applications not only run on day one but remain secure and fast years later.
What we build, we operate ourselves. That's why we build it right.
Fixed processes, documented systems, and clean handovers ensure that your project doesn’t depend on a single person.
How we work
What you can expect from us
A single point of contact
Someone who knows your project – from conception to operation.
Development and operations from a single source
We host what we build, and therefore know what matters in operations.
Your code belongs to you
Open systems and your own Git repository, meaning a storage location for your code with a complete version history. A migration is possible at any time.
Operations in Europe
Certified data centers; a data processing agreement according to GDPR is available upon request.
What we do
Infrastructure and applications that work reliably
We build infrastructure and applications that reliably perform tasks: inform, register, book, evaluate, collaborate.
Our focus is on open technologies – because they are auditable (i.e., verifiable by independent parties), extensible, and future-proof. We consciously avoid proprietary dependencies, meaning reliance on closed software from individual manufacturers.
- What we do: Managed Hosting, Managed Applications, Development, DevOps, and Operations
- For whom: Companies, public institutions, and agencies – optionally as white label, i.e., under your brand
- Values: Open Source first, data protection, transparency, longevity
Managed Hosting
Operations in European data centers: hardening (we secure the server against attacks), backups, security updates, monitoring (ongoing surveillance), and SLAs – contractually agreed availability and response times.
Managed Applications
We operate WordPress, Matomo, Mastodon, Nextcloud, and other applications for you – with updates, performance tuning, and extensions.
Development
Themes, plugins, integrations, interfaces, and migration projects.
DevOps and Automation
Development and operations intertwine: New versions are automatically tested and rolled out (CI/CD), run in containers, are checked beforehand in a test environment (staging), and can be rolled back to the previous state if necessary. Logs and metrics always show the application’s status.
For Agencies
Your technical partner in the background
From white-label hosting to the joint implementation of complex projects: We provide the technology, you remain the face to your customers.
White Label and SLAs
Operations under your agency brand or with us as your technical partner – with clear response times.
Cooperation Model
Dedicated contacts, shared roadmaps, fair margins.
Interfaces and Handovers
Clean development environments, Git workflows, documentation, and handovers for your team.
Migrations
CMS changes and relaunches without downtime, with concepts for data and redirects so old links continue to work.
You design – we provide technology, operations, and peace of mind in the background.
Our Values
What we measure ourselves by
Open Source first
We prefer free software: no dependence on a single provider, traceable code, long lifecycles.
Data protection from the start
Data protection is planned from the outset (Privacy by Design): as little data as possible, processing in Europe, logging with discretion.
Transparency
Understandable architecture, clear offers, open communication.
Robustness
Automated tests and delivery, monitoring, backups, and disaster recovery plans.
Sustainability
Maintainable solutions instead of short-term workarounds. Solid rather than spectacular and short-lived.
