SaaS and utilities

HanzDevCraft is a software studio in Germany. It builds and operates its own SaaS products and small developer utilities. It is not a construction-tech app and not an agency as the main offering.

• QATestFlow — automated QA checks on a URL: pass/fail, logs, screenshots.
• AI Visibility Monitor — checks whether ChatGPT, Claude, Gemini, Grok, and Perplexity mention a brand.
• UtilKit — in-browser tools (UUID, slug, time, JSON). Nothing is sent to a server.
• DevNexus Advisor — free Windows utility to free RAM/GPU from idle Docker, Ollama models, and leftover IDE processes.

HanzDevCraft does not publish a third-party client case-study page. Public proof is live software the studio builds and operates.

QATestFlow and AI Visibility Monitor are running SaaS products with their own sites and Stripe billing. UtilKit runs in the browser. DevNexus Advisor is a free Windows utility.

HanzDevCraft does not take custom client projects. It hosts and maintains its own products.
