Altair RapidMiner

Visual, drag-and-drop platform for data prep, machine learning, and enterprise AI, now part of Siemens.

Visit Altair RapidMiner Alternatives

RapidMiner (marketed as Altair RapidMiner until Altair's 2025 acquisition by Siemens, and now sold as a Siemens product) is a visual, drag-and-drop platform for building machine learning pipelines without heavy coding, alongside code-based extensions for Python and R users. The current portfolio bundles AI Studio (visual ML workflows), Graph Studio (knowledge graphs), Monarch (self-service data prep from documents and spreadsheets), and Panopticon (real-time visualization), positioning it as a broader enterprise AI suite rather than a single tool. It is offered both as a self-hosted deployment and as a cloud service. Pricing is not published; prospective customers must contact Siemens sales for a quote, and there is no confirmed public free tier following the ownership change.

Terms to know

Machine learning Building models that learn patterns from data to make predictions or decisions, rather than following hand-coded rules. Data pipeline The automated sequence of steps that moves data from source systems to a destination, transforming it along the way. Exploratory data analysis An open-ended first pass through a dataset to understand its structure and spot patterns before formal analysis. Knowledge graph A network of entities and the labeled relationships between them, used to represent and query structured knowledge.

How to choose a data science & ML platform The decisions that matter are who builds the models, how automated the modeling should be, and whether you want a cloud-native platform or a portable one.
