About OneQuill

Software that does exactly what it says.

OneQuill is an independent software company in Essen, Germany. We turn complex technology into tools people can run, understand and trust, starting with OneVir, our self-hosted AI gateway and inference engine.

01 What we believe

Precision is a form of respect.

Powerful technology should leave people more in control, not less. Every principle below shows up somewhere you can check in our products.

Control by default

Data stays where you put it. In OneVir, models run on your own hardware first; a request leaves only through a provider route you configured, and a single switch or header keeps it local.

Every decision explained

OneVir records why each request went where it did, what policy decided and what it cost. Audit exports never include prompts, responses or keys.

Engineered, not assembled

We prefer one well-built native process to a stack of loosely coupled services. Fewer moving parts mean fewer places for data, cost or policy to slip.

Claims you can check

We publish how performance numbers were measured, label demonstration data as such, compare ourselves against public documentation, and keep the roadmap separate from what ships.

02 Our mark

A Q and a quill.

The ring of the Q stands for the complete system we take responsibility for. The quill stands for the care of writing things down clearly: the documentation, the records and the explanations that make a system trustworthy.

Its colour runs from orange through coral and raspberry to a deep berry: warm energy, held with discipline.
