How Does KNIME Compare to Competitors?

vs Alteryx

(10) KNIME has a better free tier and is open source compared to Alteryx, which focuses on providing an alternative solution for analysts and citizen data scientists, while Alteryx provides a premium code-free analytics product for business analysts. KNIME provides a larger number of connectors than Alteryx but Alteryx is faster at preparing/blending data.

(14) KNIME is the winner based on cost and extensibility; Alteryx is the winner based on polished enterprise analytics.

vs Dataiku

(11) Both platforms are collaborative in nature, but KNIME focuses on creating low-code visual workflows, whereas Dataiku focuses on integrating MLops and AutoML into its platform. KNIME has a lower entry cost due to its free tier; Dataiku provides stronger governance features for organizations with a large number of employees.

(15) KNIME is the winner when it comes to workflow automation; Dataiku is the winner when it comes to end-to-end ML production.

vs IBM SPSS

(12) KNIME provides greater breadth of integration with data and ML capabilities compared to SPSS' statistical focus. KNIME disrupts the traditional high-cost model of SPSS, however, SPSS retains its advantage in the area of traditional statistics and reporting.

(16) KNIME is the winner when it comes to modern data science; SPSS is the winner when it comes to statisticians who need validated methods.

vs Tableau Prep

(13) KNIME provides users with a complete analytics pipeline whereas Tableau is focused on data preparation. KNIME provides more power for complex ETL/ML operations, however, it also has a steeper learning curve than Tableau's very intuitive interface.

KNIME is for entire analysis, and Tableau Prep is for visual preparation of your data for visualization.

What are the strengths and limitations of KNIME?

Pros

  • The Core Platform is completely free — unlimited workflows, and 300+ connectors for individual use.
  • A visual, low-code user interface that makes it possible for people who don’t write code (non-technical users) to build workflows and extendable for technical users to add their own logic.
  • An open-source ecosystem — a huge extension library and the ability for developers in the community to contribute back to the project.
  • Broad Integration Coverage — Connects to almost every possible data source, without needing to write any custom code.
  • Strong Enterprise Scalability — Server / Business Hub are designed for Production Deployments.
  • Active Community Forum — Extensive Examples, Templates, and Peer Support Available.

  • Poor Out-of-the-Box Collaboration — The Free Version Does Not Allow Sharing Until You Upgrade to the Business Hub.
  • Desktop-Centric Free Tier — No Web/Automation Without Paid Upgrades.
  • Enterprise Pricing Opaque — Custom Quotes Make Budgeting Difficult.
  • Performance Limits — Large Datasets Can Be Memory-Intensive If Not Optimized.
  • Limited Built-In Visualization — Requires Extensions Or External Tools To Produce Polished Dashboards.
  • Fragmented Product Family — Hub/Pro/Server Create Licensing Complexity.

What Are Common Questions About KNIME?

KNIME is a data analysis platform that allows for visual work flow creation by dragging-and-dropping nodes into a workflow based upon your needs. KNIME supports data blending, machine learning, and deployment without having to write code. The KNIME Server option also allows collaboration, and the ability to deploy for production.

KNIME is available in both a free version and is open source; allowing unlimited users, whereas Alteryx is only available in an expensive per user license model. KNIME also offers much greater extensibility by way of community developed nodes, and also supports R and Python integration. Alteryx offers a cleaner user experience but comes at a significantly larger cost.

KNIME Server includes features to manage access such as controlling who can execute, edit, and read workflows. Users can deploy their work flows on premise, to Amazon Web Services, or Microsoft Azure for ultimate control over their data. Workflows created in the community edition will only operate from a local machine.

The KNIME Analytics Platform is free and open source. The KNIME Server and team editions are priced starting at $3.00 per user for each tiered level of service, and enterprise pricing will require you to contact Alteryx sales to obtain a quote.

Yes, KNIME has in excess of 1,000 connectors for various database systems, cloud services, big data platforms (HDFS, Spark) and programming languages (Python, R). KNIME also offers a community hub called "KNIME Hub" which provides community developed work flows for various system integrations.

Free users have access to a community forum for answers to common questions, and there are many extensive online training resources. Commercial customers may contact Customer Care for assistance with obtaining a license, as well as utilize video tutorial resources provided through "KNIMETV".

The KNIME Analytics Platform is completely free to use, and has no limitations. KNIME Server does offer trial options for those interested in evaluating the product; however, they will need to fill out a contact form in order to receive this information. The KNIME Hub also offers a free tier.

The KNIME Analytics Platform is desktop focused, and the KNIME Server is a separate licensed product. Many users report that the node-based user interface takes some time to learn. Professional support for the product is limited when compared to other commercial Business Intelligence products.

Is KNIME Worth It?

KNIME excels as a low-cost, free, open source alternative to very expensive analytics platforms that are designed for data science teams. Although the visual workflow design paradigm used by KNIME has a steep learning curve, its large node ecosystem, and strong community support, makes it an excellent choice for companies looking to keep costs down. The KNIME Server provides companies with a production ready solution for deploying workflows.

What do expert reviews and research say about KNIME?

Key Findings

KNIME has a mature, free analytics platform that includes a large, active community as well as a massive library of nodes; KNIME Server allows organizations to deploy KNIME at scale in a managed manner that maintains an Open Core Model. The primary limitation of KNIME is its support structure which is geared towards supporting the community rather than providing professional services.

Risk Factors

!
Support for KNIME's Free version is dependent upon the Community
!
There is a Learning Curve to become proficient in a Node Based Interface
!
Deployment of the KNIME Server requires that you manage your own Infrastructure
!
The pricing model for Enterprise Features is not transparent

What Are the Best Alternatives to KNIME?

  • Alteryx: Enterprise Analytics Platform. With a very polished User Interface and Extensive Connectors. The user-friendly nature of this platform makes it easy for Business Users to create their own analytics platforms. The price is $5k +/user/year which is a bit high compared to some of the other platforms available. This platform is ideal for large Enterprises that have the budget to support both the cost of the software, and also the cost of support for the software. (Alteryx.com)
  • Dataiku: Data Science Collaboration Platform. With a very visual interface, and AutoML. Has more of an Enterprise feel to it in regards to Governance and Auditing. The price is a bit higher than most of the other platforms available. Has a better web based Integrated Development Environment (IDE) than KNIME. Ideal for organizations that require audit trails due to regulations such as Financial Institutions. (Dataiku.com)
  • Orange: A free visual programming platform focused on Machine Learning and Visualization. Much easier to use than KNIME. However, much less functionality for Enterprise use. Great for academic and research prototyping. (Orange.BioLab.si)
  • RapidMiner: An all-encompassing analytics platform that includes AutoML and a marketplace. While there is a free version, the free version has limitations. The commercial version will run you similar money to Alteryx. Offers many more automated Machine Learning features than KNIME. If your organization wants to offer "wizards" instead of having each member manually create workflows, then RapidMiner would be a good option. (RapidMiner.com)
  • H2O.ai: An open-source AutoML platform that is primarily used for scaleable machine learning. Not as much visual workflow capabilities as KNIME. Great for organizations that are strictly using machine learning to develop Champion/Challenger models. (H2O.ai)
