The short version

  • Only Mendix has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aha! sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user; 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: Aha! covers Strategic roadmaps, 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.

Aha!

  • Sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user
  • Roadmaps at $59 per user per month is expensive next to general project tools, and Discovery and Ideas add $39 each
  • The Develop integration with Roadmaps requires the Enterprise or Enterprise+ tier
  • Annual billing is by invoice only; monthly is card

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.
