A common question we get is: “Why shouldn’t we just use the free Mendix Unit Testing module combined with an open-source tool like Playwright, especially now that AI and MCP can help write scripts?”
If you are a small team managing only 1 or 2 simple applications, those free tools might suffice. However, our analysis shows that once your application becomes large or complex, or you scale to testing 3 or 4+ apps, MTA wins every single time.
Relying on fragmented free tools creates a massive maintenance burden at scale. Here is why enterprise teams choose MTA to future-proof their quality assurance:
