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

Microsoft SQL Server

  • Licensing and on-premises deployment costs are high compared to open-source alternatives, with Enterprise Edition exceeding $60,000 for minimum core requirements
  • Performance monitoring toolset is insufficient for hybrid cloud environments requiring real-time analytics across multiple deployment types
  • Heavy I/O resource consumption can saturate disk volumes and degrade performance when processing large transaction workloads
  • Always On availability groups with up to 8 secondary replicas are limited to Enterprise edition only; Standard supports only basic availability groups with 2 replicas
  • CPU and memory scaling is capped at 4 sockets or 32 cores on Standard edition, limiting deployments requiring higher compute capacity

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

Microsoft SQL Server: What is the pricing model for SQL Server?

SQL Server uses core-based licensing with per-2-core pack pricing. Enterprise Edition costs approximately $15,123 per 2-core pack (minimum 8 cores). Standard Edition costs approximately $3,945 per 2-core pack. Developer and Express editions are free. Software Assurance adds 25-35% annually for upgrades and support.

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.

Microsoft SQL Server: Does SQL Server run on Linux?

Yes. SQL Server 2017 and later run on Linux (Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Ubuntu), Docker containers, and Windows with feature parity including Always On availability groups, Active Directory authentication, and encryption.

Source

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

Microsoft SQL Server: Is there a free edition of SQL Server?

Yes. SQL Server Express is free and includes all functionality of Enterprise edition for development and testing, with limits of 4 cores, 1,410 MB memory per instance, and 50 GB per database. Developer edition is also free for non-production use.

Source
Microsoft SQL Server: Can SQL Server be deployed offline?

Yes. SQL Server can be installed from offline media on machines without internet access. Microsoft provides complete offline installation packages for SQL Server, SSMS, and supporting components, making deployment in isolated or air-gapped environments feasible.

Source
Microsoft SQL Server: What high availability options does SQL Server provide?

SQL Server offers Always On availability groups (Enterprise only), Always On failover cluster instances, database mirroring, log shipping, and for disaster recovery, failover servers in Azure and Accelerated Database Recovery for faster recovery after failures.
