Open source & custom integrations
Much of what we build runs on open source: Linux, containers, Kubernetes and Git workflows. We write custom software and APIs when no product fits.
Much of what we build runs on open source: Linux, containers, Kubernetes and Git workflows. Open components keep costs down and avoid lock-in, and our engineers know how to run them in production, patch them and read the code when something misbehaves.
When no product fits, we write custom software and APIs and hand over the source code, documentation and deployment steps. The law firm platform and the weaving factory system are examples on the track record page. Security review by our own testers is part of the build.
What we do
- Linux server builds and hardening
- Docker containers and Kubernetes clusters
- Custom APIs and integrations
- CI pipelines and Git workflows
- Self-hosted platforms replacing paid products
- Python, Node.js and Rust development
- Documentation and handover
- Monitoring and update routines
We document and hand over what we build, so clients can run it themselves or keep us to run it. Languages we use include Python, Node.js and Rust.
This group is the engineering base of Tailored Software and supports every other practice with scripts, integrations and tooling.

How we use Open source & custom integrations for clients
Where this matters most
Frequently asked questions
Direct answers to the questions we hear most. Something else on your mind?
Send us a messageCan you work with hardware from any manufacturer?
In most cases. Our team has worked with virtually every hardware manufacturer, but check specific models with us.
Who maintains custom code afterward?
We can, under Managed IT, or hand it over with documentation.
Is open source secure enough for business use?
Yes, when it is chosen, patched and operated well. Security depends on the project's maintenance, how fast you apply updates and how it is configured. We check the project's activity and release history, and track vulnerabilities for what we deploy.
When do you use Kubernetes?
When you have many services that need scaling, rolling updates and self-healing across several hosts. For a few applications, plain containers or virtual machines are simpler and cheaper to run. We avoid adding a platform that your team would struggle to operate.
Will we be locked in to the code you write?
No. You receive the source in a repository you control, documentation, build and deployment instructions, and a handover session. Open standards and common languages mean another team can take it over.
How do you keep custom software updated?
With automated tests and a build pipeline, dependency update checks and a scheduled maintenance window. Security fixes in libraries are applied quickly and tested before release. A maintenance agreement is optional.
