RapidMiner has had two owners in three years. Altair completed its purchase of the company on September 16, 2022 and renamed the desktop tool Altair AI Studio. Siemens then closed its roughly USD 10 billion takeover of Altair on March 26, 2025. Today the Siemens product page sells the software as RapidMiner AI Studio and says it is "now part of Intelligence Center x".
The product still works, with the same drag-and-drop canvas plus Python and R. What changed is access. Siemens sells it by quote, with no public trial or free edition, and old download links now land on marketing pages. That pushes students, small teams and anyone on an expired licence to look elsewhere.
The seven tools below cover the main reasons people leave: a free visual canvas, a team platform in the browser, a vendor with a published price, or a code-first library. KNIME comes first because a RapidMiner process maps onto a KNIME workflow with the least relearning.
Prices below are as of November 6, 2026. Our method is on How we review tools.

KNIME
A RapidMiner process is a chain of operators on a canvas. KNIME calls them nodes and the chain a workflow, and the idea is the same. Readers, joins, filters, learners, scorers and writers all exist as nodes, and you can drop in a Python or R script node where the built-ins stop. The KNIME Analytics Platform itself is free and open source, so a RapidMiner user can rebuild an existing process without asking anyone for a budget.
The paid tier is about running work, not building it. The KNIME Pro page lists €19 a month for cloud execution with 120 credits and 500 K-AI assistant interactions, plus schedules down to every minute. Larger teams move to Business Hub, which KNIME prices by capacity rather than by seat.
Best for: Analysts who want to rebuild RapidMiner processes on a free, open source canvas.
Pricing:
- Analytics Platform: free and open source
- Pro: €19 a month, 120 credits and 500 K-AI interactions; extra credits €0.025 each
- Team and Business Hub: priced by capacity through a sales form
Watch out for:
- Pro credits go quickly. The smallest executor burns 1 credit a minute, so the included 120 credits last about two hours of runtime.
- Expect to rebuild each process by hand. RapidMiner saves .rmp process files and KNIME uses its own workflow format, so nothing carries over automatically.
Official site: KNIME.
Orange
Students who learned RapidMiner on a free academic licence often land here. Orange, from the University of Ljubljana, uses widgets on a canvas, and every chart or model updates live as you change an upstream step. That feedback loop suits a classroom, even though Orange has far fewer operators than RapidMiner.
Version 3.40.0 shipped on December 20, 2025, with a Windows installer, a portable Windows zip, separate builds for Apple Silicon and Intel Macs, and pip or conda packages. Add-ons cover text mining, image analytics, networks and time series. Our Orange Data Mining alternatives page covers where it runs out of room.
Best for: Courses and solo exploration of small and medium datasets.
Pricing:
- Free and open source under GPL v3 or later; no paid tier
Watch out for:
- Everything runs on one machine. There is no server, scheduler or web version, per the download page, which lists only desktop builds.
Official site: Orange.
Dataiku
Dataiku replaces the RapidMiner Studio plus AI Hub pairing with one browser platform. Analysts build visual recipes in a project "flow", data scientists add Python, R or SQL steps in the same project, and the platform handles scheduling, model deployment and access control. That makes it the most direct answer for a team that used RapidMiner as a shared enterprise system, not a personal desktop app.
The get-started page offers a 14-day Dataiku Cloud trial with no credit card. The trial instance includes an API node with one API service, 4 CPUs and 32GiB of elastic compute. A Free Edition can also be installed on your own Mac or Linux machine.
Best for: Teams that need analysts and coders working in the same governed projects.
Pricing:
- Dataiku Cloud: 14-day free trial, no card
- Free Edition: self-installed
- Paid plans: no public price; contact sales
Watch out for:
- Windows support for the Free Edition is labelled "experimental" on the get-started page.
- With no published prices, the cost after the trial is unknown until you talk to sales.
Official site: Dataiku.
Alteryx One
Alteryx sells to business analysts rather than data scientists. Its Designer canvas is strongest at blending spreadsheets, databases and files, cleaning them and pushing results to reports, with predictive tools layered on top. A RapidMiner user who mostly did ETL and scoring, not model research, will find it familiar.
It is also one of two vendors here with a list price, alongside IBM SPSS Modeler. The Alteryx pricing page shows the Starter edition at $250 per user per month, billed annually, for 1 to 10 users. Professional and Enterprise are quote-only, add desktop and hybrid use, and include 50 and 15,000 automation runs. A 30-day free trial of Alteryx One is offered.
Best for: Business analysts who automate data preparation and reporting more than model building.
Pricing:
- Starter: $250 per user per month, billed annually, 1 to 10 users
- Professional: contact sales; 50 automation runs
- Enterprise: contact sales; 10+ users, 15k automation runs, free viewer licences
- 30-day free trial
Watch out for:
- Starter is cloud only and connects to flat files only, per the pricing page. Database connectors and the desktop app need Professional or above.
- The entry tier works out to $3,000 per user a year, and every step up is quote-only.
Official site: Alteryx One.
IBM SPSS Modeler
SPSS Modeler started life as Clementine and has competed with RapidMiner for years. It uses streams of nodes for data prep, modeling and scoring and runs as a desktop app on Windows and Mac. For a company that wants a big vendor behind its visual modeling tool, it is the closest like-for-like option.
IBM publishes one figure. The SPSS Modeler pricing page says subscriptions start at USD 529 a month, described as indicative pricing for one authorized user on a one-year term, including updates and support. Professional, Premium and Gold are one-time purchases with no price shown; Premium adds text analytics and Gold adds Collaboration and Deployment Services.
Best for: Enterprises that want a supported desktop modeling tool from a large vendor.
Pricing:
- Subscription: from USD 529 a month, one authorized user, one-year term
- Professional, Premium, Gold: one-time purchase, no public price
- Free trial offered; length not stated
Watch out for:
- Price is the main barrier. USD 529 a month works out to over USD 6,000 a year for one seat, before any deployment server.
- There is no Linux desktop app. The pricing page names only Windows and Mac.
Official site: IBM SPSS Modeler.
H2O-3
Some RapidMiner users mainly used Auto Model to throw a dataset at many algorithms and compare the results. H2O-3 does that from code. It is an open source, distributed machine learning engine with gradient boosting, random forests, GLMs, deep learning and an AutoML function that trains and ranks models for you. You drive it from Python, R or a REST API.
PyPI lists version 3.46.0.12, uploaded on August 12, 2026, under the Apache 2.0 licence. The engine runs on Java, so it works on any operating system, and it can spread a job across a cluster when one machine is not enough.
Best for: Data scientists who want free AutoML from Python or R instead of a canvas.
Pricing:
- H2O-3: free and open source, Apache 2.0
- H2O.ai's commercial platform: contact sales
Watch out for:
- Its only point-and-click interface, H2O Flow, "is deprecated and will be removed in a future release", the Flow documentation says, so plan on writing code.
- Model export as POJO or MOJO from Flow is blocked in the open source build and needs H2O-3 Secure, per the same page.
Official site: H2O-3.
Weka
RapidMiner users may know Weka from the old Weka extension that added its learners as operators. Weka, from the University of Waikato, is still the standard machine learning workbench in textbooks. The Explorer runs dozens of classifiers, clusterers and attribute selectors on one dataset, and the Experimenter compares them with proper statistics.
The Weka download page lists 3.8.7 as the stable release. The Windows and macOS installers bundle their own Java runtime, so setup there takes one download. On Linux you unpack a .zip and start Weka with the weka.sh script. Its Knowledge Flow view gives a node canvas for chaining steps.
Best for: Students and researchers comparing many algorithms at no cost.
Pricing:
- Free and open source under the GNU GPL
Watch out for:
- The 3.9 development branch may break backwards compatibility, the download page warns, so coursework should stay on 3.8.
- Data preparation is thin compared with RapidMiner's Turbo Prep and blending operators.
Official site: Weka.

When to stay with RapidMiner
Stay with RapidMiner AI Studio if your company already holds a Siemens or Altair licence and runs production processes on AI Hub. Rebuilding dozens of processes in another tool costs more than a renewal. Siemens also offers cloud, on-premises and hybrid deployment at workgroup or enterprise scale under one vendor, which matters to IT teams that dislike stitching tools together.
Frequently asked questions
Is RapidMiner still available?
Yes, under a new name and owner. Siemens sells it as RapidMiner AI Studio within Intelligence Center x, with AI Cloud and AI Hub alongside it. The product page has no price or buy button, so access goes through Siemens sales.
Who owns RapidMiner now?
Siemens. Altair bought RapidMiner in September 2022, and Siemens completed its acquisition of Altair on March 26, 2025, per the closing announcement.
Is there a free version of RapidMiner?
The Siemens product page does not mention a free edition, a trial or an education licence. For a free tool with the same canvas idea, KNIME and Orange are both open source.
Is KNIME better than RapidMiner?
For most small teams, yes, because the full desktop app is free and open source, with a large node library and community extensions. RapidMiner is easier to justify only when you need Siemens support or already run AI Hub in production.
