Mendix testing, driven by AI.
Rheonox QA+ tests your Mendix applications like a real user, catches the anti-patterns your teams miss, and explains the fixes in plain language — without installing a single module in your app.
The problem
AI ships more code — and more bugs.
Teams release faster than ever. But manual testing can't keep up: regressions, performance anti-patterns and Mendix misconfigurations stay invisible until production, where they cost the most.
Millions spent, bugs still invisible.
Every year, millions go into manual testing and audits. Meanwhile, critical bugs slip into production unseen.
An expertise problem, not brute force.
Software testing is an expertise problem. An AI agent that specialises in Mendix catches what ten manual testers won't.
A dedicated digital co-worker.
QA+ isn't just another tool: it works alongside you, autonomously, with deep technical knowledge of the Mendix platform.

What QA+ does.
An AI co-worker that records, replays, verifies and explains — Mendix-specialised end to end.
Recorder & Replay
Record your user journeys with a Chrome extension, replay them on every deployment via a Linux runner. Nothing to install in your application.
Rich visual assertions
Existence, text, state, attributes, DOM snapshots… QA+ validates what the user actually sees, not just the code.
Mendix anti-pattern debugger · beta 2026
Detects N+1 queries, costly microflows and risky configurations — the Mendix-specific traps a generic tool ignores.
AI Advisor · 2026
Plain-language recommendations: QA+ doesn't just flag what fails, it explains why and how to fix it.
Positioning
Why QA+, and not another tool.
Three design choices, built for the regulated enterprise — where other approaches compromise.
Mendix-specialised
A generic tool ignores the microflows, widgets and anti-patterns specific to Mendix. QA+ is built for the platform — it sees what a hastily "adapted" tool never will.
Non-intrusive
Traditional Mendix approaches integrate into your model or project. QA+ tests from the outside, like a real user — nothing to install, nothing to maintain in your app, no production risk.
Local & sovereign AI
Most AI platforms send your data to a third-party cloud, often outside Europe. QA+ runs in your own infrastructure. Your data never leaves your perimeter. GDPR & FADP compliant.
Why Rheonox QA+.
Deep Mendix specialisation
Not a generic QA tool adapted to Mendix: Mendix experts who built a dedicated product — widgets, microflows, platform-specific anti-patterns.
No intrusion into your systems
QA+ works without installing any module in your applications. No risk to production. Compatible with the strictest IT policies (industry, government, banking).
Local, sovereign AI
The intelligence runs in your infrastructure (on-premise or private cloud). Your data never leaves your perimeter. GDPR-compliant and aligned with Swiss data-sovereignty requirements (FADP).
Built for the European enterprise
Designed from day one for large-account constraints: compliance, audit, environment separation, multi-tenancy. Not a tool retrofitted along the way.
