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

Alooma

Alooma lets developers transform data within the data pipeline before loading via Code Engine, an in-browser Python environment.

Fivetran

Fivetran is an ELT tool. It does not transform data prior to loading. It recently added beta support for post-load transformations via copy-and-paste SQL.

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.

Alooma

Alooma integrates with about 30 databases and SaaS data sources. Customers can request that Alooma build a new data source, but no one outside of the Alooma team can build new data sources or make improvements to existing sources. It used to support several data warehouse and data lake destinations, but since the company was purchased by Google, new Alooma customers can use only Google Cloud Platform as a destination.

Fivetran

Fivetran offers connectors for more than 100 data sources. It supports more than a dozen data warehouse destinations, but no data lakes. Customers can request that Fivetran build a new data source, but no one outside of the Fivetran team can build new data sources or make improvements to existing sources.

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.

Alooma

Alooma provides support via Zendesk through a form on its website. Documentation is comprehensive. The company doesn't provide training services.

Fivetran

Fivetran provides support through an in-app form. Documentation is comprehensive. Fivetran does not 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

Alooma

Alooma doesn't disclose pricing.

Fivetran provides a 14-day free trial, and does not disclose pricing.
