The short version

  • Each has a real cost: Bubble apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.; 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: Bubble covers Visual app editor, 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.

Bubble

  • Apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.
  • Complex apps can hit performance limits compared to hand-coded applications as data and workflow complexity grows.
  • The visual workflow editor has a steep learning curve for genuinely complex business logic.
  • Free tier cannot host apps on a custom domain, limiting it to prototyping rather than production launches.

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.
