The short version

  • Only RapidMiner has a free tier, so it costs nothing to try first.
  • Each has a real cost: RapidMiner processes are stored as the product's own XML, so they cannot be meaningfully diffed, reviewed in a pull request or executed anywhere else, and a team's accumulated work is not portable in any practical sense.; Zscaler Internet Access the pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost
  • They diverge on capability: RapidMiner covers Visual process canvas, Zscaler Internet Access covers Secure web gateway.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

RapidMiner

  • Processes are stored as the product's own XML, so they cannot be meaningfully diffed, reviewed in a pull request or executed anywhere else, and a team's accumulated work is not portable in any practical sense.
  • The operator library is the ceiling, and anything beyond it means dropping into an embedded Python or R operator, at which point the code sits inside a visual container that provides none of the version control, testing or debugging a normal repository would.
  • Two changes of ownership in three years, Altair in 2022 and Siemens thereafter, have already moved the product's name, packaging and licensing, so a buyer is committing to a roadmap decided inside a much larger engineering software business.
  • Licensing draws on Altair's shared units pool, so running heavy modelling work consumes capacity that other teams in the organisation were relying on for different products, which makes cost attribution and capacity planning awkward.
  • Scheduling and deployment require AI Hub as a separate server product to install, license and operate, so a model built on the desktop is not in production until another purchase and another installation have been completed.

Zscaler Internet Access

  • The pricing page names two base tiers, Essentials Platform and Zscaler Platform, plus modular add ons including three Digital Experience Monitoring tiers, but publishes no dollar figures anywhere and routes buyers to a demo request for cost

Answered from the vendors’ own pages

RapidMiner: Is it still called RapidMiner?

The desktop product is now Altair AI Studio and the server is Altair AI Hub. The RapidMiner name persists in documentation, community material and most search results, which makes finding current information harder than it should be.

Zscaler Internet Access: How many pricing tiers does Zscaler Internet Access offer?

Zscaler Internet Access offers two main platform bundles: the Essentials Platform (entry-level) and the Zscaler Platform (comprehensive). Specific pricing is not published online.

Source
RapidMiner: Is there a free version?

Altair has offered free and academic editions with usage limits, but the terms have moved with each ownership change, so check what is currently on offer rather than relying on what the free tier allowed a few years ago.

Zscaler Internet Access: Are there optional add-on modules available?

Yes. Zscaler offers extensive optional capabilities in five categories including Inline Cyberthreat Protection, Private Access enhancements, Data Security, Security Operations, and Zero Trust Branch.

Source
RapidMiner: Do I need to write code?

No, which is the point of it. You will write some once you hit the edge of the operator library, and at that stage the tool works against you rather than for you.

Zscaler Internet Access: How is Zscaler Zero Trust Branch priced?

Zero Trust Branch is sized by encrypted throughput (200 Mbps to 10 Gbps) or endpoint count (200 to 5,000 endpoints), with pricing varying by configuration.

Source
RapidMiner: Can I put a model into production?

Through AI Hub, which is a separate licensed server. The desktop tool builds and validates; it does not schedule or serve.

Zscaler Internet Access: How do I get Zscaler pricing?

Zscaler does not publish pricing online. You must request a demo or contact their sales team to receive a pricing quote.

Source
RapidMiner: How does licensing work?

Through Altair's units model, where a pool of purchased units is drawn on by whichever Altair products your organisation runs, rather than a per-seat licence specific to this product.
