Mendix

Mendix is a Rotterdam-founded, model-driven low-code platform for building enterprise applications, acquired by Siemens in 2018 and now sold as part of Siemens’ Digital Industries Software portfolio under the Siemens Intelligence Center X banner.

That ownership is worth stating plainly: Siemens AG is itself headquartered in Munich, Germany, so the acquisition keeps Mendix inside the EU rather than moving it offshore, while giving the platform a much larger balance sheet and — for manufacturers already running Siemens’ industrial software — a more direct line into OT and PLM systems than a standalone low-code vendor could offer.

The platform’s defining technical choice is baking version control into the modeling environment itself, so multiple developers working on the same application get the kind of change history and merge conflict handling that most low-code tools only approximate.

Pricing starts with a genuinely free tier for prototypes, then splits into a One App plan from €918/month and an Unlimited Apps plan from €2,295/month — Mendix is explicit that there's no technical difference between the two, only how many applications the licence covers. The Premium tier, which adds multi-region failover, a private marketplace and 24/7 support, is quote-only.

The trade-off is scale and complexity: this is built for organisations replacing core systems with a governed development process, not a small team shipping its first internal app, and the per-application pricing model means a company running many small tools will find the maths works against it. For an enterprise that wants an EU-domiciled low-code platform with real version control and Siemens-grade backing, it remains one of the most credible options in this category.

What Mendix does well

• Rotterdam-founded, still the platform’s operational home, with genuine enterprise scale behind it since Siemens’ 2018 acquisition
• Version control and collaborative development built into the platform itself, not bolted on
• Published entry pricing for the Standard tier — unusual for an enterprise-grade low-code platform
• Part of Siemens’ Digital Industries Software estate, which matters for manufacturers already running Siemens OT/industrial software

Where Mendix falls short

• Premium tier, the one enterprises actually need for HA and multi-region failover, is quote-only
• Pricing is metered by application count rather than a flat seat price, which punishes a company running many small apps
• Being owned by Siemens since 2018 means the roadmap now answers to a much larger parent company's priorities, not just Mendix's own
• Free tier explicitly excludes any support plan or uptime guarantee

Standout feature. Version control built directly into the modeling environment — every change to an application is tracked the way a developer would track code, which is unusual among low-code tools and matters once more than one person is building the same app.
