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

Dell Boomi

Boomi handles process execution through procedures it calls shapes. Boomi supports a set of prebuilt transformations within its various shapes (such as text encoding, encryption/decryption, search/replace, and combining documents), and it lets users create custom preload transformations by coding JavaScript or Groovy scripts to convert data from the source application into a format that can be used by the destination.

Improvado

Improvado provides preload transformations on data moved through the Improvado UI. Improvado transforms data into a format that they believe to be better for users, but it doesn't support user-configured transformations. Improvado also lets customers move raw data to a destination by writing code that calls their API.

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.

Dell Boomi

Like other application integration platforms, Boomi typically replicates data changes one at a time between multiple systems, as events happen, rather than pushing batches of data to a single central repository. Boomi supports two kinds of connectors, which it calls application and technology connectors. There are 80 application connectors (mostly to SaaS platforms, including data warehouses and data lakes) and 22 technology connectors (to databases and services like SFTP, HTTP, and IMAP). Developers can write their own custom connectors in Java using Boomi's Connector SDK.

Improvado

Improvado supports about 80 integrations to SaaS platforms. Several other data sources are "available by request only." Improvado supports Amazon Redshift and Google BigQuery data warehouses; Amazon S3 and Google Cloud Storage data lakes; and PostgreSQL, MySQL, Microsoft SQL Server, and Postgres Plus database destinations. 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.

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.

Dell Boomi

All customers get email support, and customers on premier support plans get live chat and phone support. Dell also offers Boomi consulting, including onsite consulting for support. Documentation on Dell's help site is comprehensive. A community site provides additional peer and company support. Dell offers on-demand and instructor-led digital training.

Improvado

Improvado provides support through Intercom online chat and via email. Documentation is provided in the form of how-to articles. The company doesn't provide training services.

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

Dell Boomi

Plans are billed monthly, starting with a rate of $549 per month. A 30-day free trial is available.
