Software, AI-driven. Built locally.
AI-driven, built locally, spec-driven and tested — custom software and integrations around the rzfz.ai Stack, by razzfazz.ai GmbH.
Winner — Constantinus Award 2026AI-driven Software Engineering
Software gets built here the same way we recommend it to our customers: AI-driven, local, traceable. We build integrations and extensions around the rzfz.ai Stack — the integrated open-source stack for local AI infrastructure — as well as custom software: connecting your existing systems, workflow automation, interfaces, custom modules.
We work with the same tools we ship: local coding agents with access to our Gitea, specification-driven development, automated test coverage. At one customer, an agent raises unit-test coverage around the clock — we bring the same way of working to your projects.
24×7 dev agent raising test coverage
A local coding agent works around the clock on the in-house repository: writing unit tests, steadily raising coverage and opening merge requests — with no code ever leaving the infrastructure.
Use caseLocal coding with on-box models
Developers use coding models directly on their own hardware — completion, reviews and refactorings without external API keys and without code leaving the premises.
AI-driven engineering — local
Our coding agents run on your own box — no source code, no prompt, no project file ever leaves the building. AI-driven engineering that follows the same sovereignty rules as the stack we ship.
Consulting & digitalization — by SEQIS.ai
Strategic consulting, digitalization roadmaps and transformation support around the rzfz.ai Stack are delivered by our sister company SEQIS.ai — the consulting and digitalization house of the SEQIS Group. From the potential analysis through the EU AI Act roadmap to rollout support.
AI and digitalization are changing how companies work — switching without a plan costs quality. SEQIS.ai guides your team step by step: potential analysis, tool selection, workshops, architecture review. Pragmatic, measurable, no buzzwords.
