Most businesses have data stored in a variety of locations, from in-house databases to SaaS platforms. To get a full picture of their finances and operations, they pull data from all those sources into a data warehouse or data lake and run analytics against it. But they don't want to build and maintain their own data pipelines.

Fortunately, it’s not necessary to build everything in-house. We put together this ETL tool comparison guide to help you choose the product that’s the best fit for your business.

Let's dive into some of the details of each platform.

Transformations

Hevo Data

Hevo offers preload transformations via code written in Python. Hevo can run transformation code for each event in the pipelines you set up. To perform transformations you must edit the properties of the event object received in the transform method as a parameter.

Pentaho Data Integration (Kettle)

Pentaho supports a wide variety of pre- and post-load transformations through dragging and dropping more than two dozen kinds of operations onto its work area. In addition, users can drag and drop custom scripts in Python, Java, JavaScript, and SQL onto the canvas.

Stitch

Stitch is an ELT product. Within the pipeline, Stitch does only transformations that are required for compatibility with the destination, such as translating data types or denesting data when relevant. Stitch is part of Talend, which also provides tools for transforming data either within the data warehouse or via external processing engines such as Spark and MapReduce. Transformations can be defined in SQL, Python, Java, or via graphical user interface.

Connectors: Data sources and destinations

Each of these tools supports a variety of data sources and destinations.

Hevo Data

Hevo supports about 40 integrations to SaaS platforms, databases, files, and BI and analytics tools. It supports 10 destinations, including Amazon Redshift, Google BigQuery, and Snowflake data warehouses; Amazon S3 data lakes; and PostgreSQL, MySQL, and MariaDB databases. Customers can request that the company build a new data source or destination, but no one outside of the company can build new ones or make improvements to existing ones.

Pentaho Data Integration (Kettle)

Pentaho can take many file types as input, but it can connect to only two SaaS platforms: Google Analytics and Salesforce. It connects to more than 40 databases, as sources or destinations, via JDBC, ODBC, or plugins.

Stitch

Stitch supports more than 100 database and SaaS integrations as data sources, and eight data warehouse and data lake destinations. Customers can contract with Stitch to build new sources, and anyone can add a new source to Stitch by developing it according to the standards laid out in Singer, an open source toolkit for writing scripts that move data. Singer integrations can be run independently, regardless of whether the user is a Stitch customer. Running Singer integrations on Stitch’s platform allows users to take advantage of Stitch's monitoring, scheduling, credential management, and autoscaling features.

Support, documentation, and training

Data integration tools can be complex, so vendors offer several ways to help their customers. Online documentation is the first resource users often turn to, and support teams can answer questions that aren't covered in the docs. Vendors of the more complicated tools may also offer training services.

Hevo Data

Hevo provides support through Intercom online chat and via email. Documentation is comprehensive. The company doesn't provide training services.

Pentaho Data Integration (Kettle)

Pentaho provides support through a support portal and a community website. Premium support SLAs are available. There's no live support within the application. Documentation is comprehensive. Pentaho provides free and paid training resources, including videos and instructor-led training. A certification program is also available.

Stitch

Stitch provides in-app chat support to all customers, and phone support is available for Enterprise customers. Support SLAs are available. Documentation is comprehensive and is open source — anyone can contribute additions and improvements or repurpose the content. Stitch does not provide training services.

Pricing

Hevo Data

Hevo provides two monthly pricing tiers: Starter ($499) and Business ($999), as well as a monthly Enterprise plan that allows for private hosting. Annual contracts that provide a 20% discount are available. The company offers a 7-day free trial.
