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.; Splunk Enterprise Security splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
- They diverge on capability: RapidMiner covers Visual process canvas, Splunk Enterprise Security covers Security monitoring.

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.
Splunk Enterprise Security
- Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
- Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
- UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
- The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price

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.
Splunk Enterprise Security: How much does Splunk Enterprise Security cost?
Splunk Enterprise Security pricing is not published. The product is available in Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition with UEBA, SOAR, and Automated Threat Analysis. Customers must contact Splunk sales for pricing quotes on either edition.
SourceRapidMiner: 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.
Splunk Enterprise Security: What editions of Splunk Enterprise Security are available?
Splunk Enterprise Security offers Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition which adds UEBA (User and Entity Behavior Analytics), SOAR (Security Orchestration, Automation and Response), and Automated Threat Analysis.
SourceRapidMiner: 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.
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.
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.
