The short version

  • Each has a real cost: Boomi most pricing requires contacting sales; no transparent plan costs published; 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.
  • They diverge on capability: Boomi covers Cloud integration, Mendix covers Visual app and process modelling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Boomi

  • Most pricing requires contacting sales; no transparent plan costs published
  • Free trial is 30 days but requires sign-up
  • Base plan limited to one environment and two users

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.
