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.

Etleap, Apache Airflow, and Stitch are all popular platforms. Here's a side-by-side look at how they stack up against each other.

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

Transformations

Etleap

Etleap supports transformation such as parsing, extracting, translating, and filtering in the data pipeline via a graphical interface.

Apache Airflow

Apache Airflow is a powerful tool for authoring, scheduling, and monitoring workflows as directed acyclic graphs (DAG) of tasks. A DAG is a topological representation of the way data flows within a system. Airflow manages execution dependencies among jobs (known as operators in Airflow parlance) in the DAG, and programmatically handles job failures, retries, and alerting. Developers can write Python code to transform data as an action in a workflow.

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.

Etleap

Etleap supports more than 50 data sources, including databases, cloud services, and file and event streams. Customers can request that the company build a new data source, but no one outside of the company can build new data sources or make improvements to existing sources. The only destination it supports is Amazon Redshift.

Apache Airflow

Airflow orchestrates workflows to extract, transform, load, and store data. It run tasks, which are sets of activities, via operators, which are templates for tasks that can by Python functions or external scripts. Developers can create operators for any source or destination. In addition, Airflow supports plugins that implement operators and hooks — interfaces to external platforms. The Airflow community has built plugins for databases like MySQL and Microsoft SQL Server and SaaS platforms such as Salesforce, Stripe, and Facebook Ads.

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.

Etleap

Etleap provides in-app chat support. It doesn't provide training services.

Apache Airflow

The open source community provides Airflow support through a Slack community. Documentation includes quick start and how-to guides. Other than a tutorial on the Apache website there are no training resources.

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

Etleap

Etleap doesn't disclose pricing. The company offers a free trial, but only after potential customers sit for a demo from a sales engineer.

Apache Airflow

Airflow is free and open source, licensed under Apache License 2.0.

Stitch

Stitch has pricing that scales to fit a wide range of budgets and company sizes. All new users get an unlimited 14-day trial. After the trial, there's a free plan for smaller organizations and nonproduction workloads. Standard plans range from $100 to $1,250 per month depending on scale, with discounts for paying annually. Enterprise plans for larger organizations and mission-critical use cases can include custom features, data volumes, and service levels, and are priced individually.
