KNIME provides data analysis tools and a visual workflow builder for data science solutions.
About KNIME
KNIME is a platform for data analysis and data science. Users build workflows in a visual editor by connecting nodes, where each node performs a discrete action on data, such as reading, transforming, merging, training, predicting, or writing. Workflows can run node by node, in segments, or all at once. The homepage lists uses including ETL, data analytics, predictive AI, and data-aware agent building, and examples such as cleaning and filtering data, comparing budget against actual spend, and decision-tree analysis of customer churn.
The homepage says the platform connects to a wide range of data sources and AI models, including cloud data warehouses, Microsoft and Google tools, and LLM providers. It also describes automated testing, validation, deployment, monitoring, and retraining of models, with options to deploy on premises or in the cloud. The homepage says commercial teams use KNIME to keep sensitive data safe and to validate and monitor models, but it does not describe the specific controls involved. Pricing is not stated in the source material.
