The short version

  • Each has a real cost: Mendix the platform fee explicitly excludes compute and infrastructure costs, so the real all-in bill is the subscription plus a separate, less predictable cloud hosting charge.; WeWeb there is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.
  • They diverge on capability: Mendix covers Visual app and process modelling, WeWeb covers Backend agnostic.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Mendix

  • A company building exactly one production app that wants the lower One App tier rather than paying for unlimited apps it does not neednot WeWeb
  • An enterprise standardising on Mendix across many departments where the Unlimited Apps tier amortises wellnot WeWeb
  • A team wanting to evaluate low-code at zero cost before committing to a paid production tiernot WeWeb

WeWeb

  • Building an interface over data that already lives in Supabase or PostgreSQLnot Mendix
  • Agency work where the client contract requires an application that runs without the vendornot Mendix
  • Replacing the front end of a no-code application that has outgrown its original platformnot Mendix
  • Internal tools for staff where the database and its permissions already exist and must not be duplicatednot Mendix

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mendix

  • The platform fee explicitly excludes compute and infrastructure costs, so the real all-in bill is the subscription plus a separate, less predictable cloud hosting charge.
  • The jump from a free or One App tier to Unlimited Apps is a large discrete price step (roughly 918 to 2,295 euros a month at published starting rates), not a gradual scale-up, which punishes a team that grows from one app to two.
  • Being a Siemens business unit means Mendix roadmap priorities can be shaped by Siemens' broader industrial software strategy rather than purely by low-code market demand.
  • Deployment flexibility across Mendix Cloud, Azure, Kubernetes and SAP BTP is a strength on paper but means the actual infrastructure cost and complexity vary significantly by choice, complicating like-for-like vendor comparisons.
  • Premium-tier features and enterprise governance capabilities are quote-only, so a buyer cannot fully compare Mendix's top tier against OutSystems or Appian without entering a sales process.

WeWeb

  • There is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.
  • Self-hosting and the more useful delivery options sit on higher tiers, so on entry plans you are hosting with WeWeb and depending on its uptime for a production application.
  • The learning curve is closer to a front-end framework than to a drag and drop builder; collections, bindings and state assume you understand how data flows through an interface, which defeats non-technical buyers.
  • Output is web only. There is no native mobile build, so anything that must appear in the App Store needs a wrapper or a different tool entirely.
  • It is a small European vendor competing against far larger platforms, so procurement teams that assess supplier viability, support depth and long-term roadmap will need convincing before signing.

Answered from the vendors’ own pages

Mendix: What is the difference between One App and Unlimited Apps?

One App licenses a single application in production; Unlimited Apps covers any number of apps under one subscription, at a materially higher starting price.

WeWeb: Do I need another product to use WeWeb?

Yes. It builds the front end only. You need a backend such as Supabase, an existing database or an API before the application does anything useful.

Mendix: Does the licence include hosting?

No. Mendix states explicitly that compute and infrastructure resources are billed separately from the platform licence, regardless of deployment target.

WeWeb: Can I host the app myself?

On the higher tiers, yes. That is one of the main reasons agencies choose it, because the delivered application can run without the vendor in the path.

Mendix: Who owns Mendix?

Siemens, which acquired Mendix in 2018 and runs it as part of its industrial software portfolio.

WeWeb: Is it suitable for someone who cannot code?

Less so than most no-code builders. You do not have to write code, but you do have to think like a front-end developer about state, collections and bindings.
