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 code everything in-house. Here's an comparison of three such tools, head to head.

About CloverDX

CloverDX (formerly CloverETL) is a data integration platform for designing and running data jobs through a graphical user interface.

About Elastic Logstash

Elastic is the corporate name of the company behind Elasticsearch. Logstash is a command-line tool that runs under Linux or macOS or in a Docker container. It integrates log data into the Elasticsearch search and analytics service. Elasticsearch, Logstash, and Kibana make up the company's ELK Stack.

About Stitch

Stitch Data Loader is a cloud-based platform for ETL — extract, transform, and load. More than 3,000 companies use Stitch to move billions of records every day from SaaS applications and databases into data warehouses and data lakes, where it can be analyzed with BI tools. Stitch is a Talend company and is part of the Talend Data Fabric.

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

Transformations

CloverDX

CloverDX (formerly CloverETL) provides a wide variety of pre-load transformations through a drag-and-drop interface. Developers can modify or write transformations using Java or CloverDX Transformation Language (CTL).

Elastic Logstash

Logstash provides plugins for several kinds of transformations, including filtering and deserializing data, extracting fields, and enriching data with lookups. Filters are text files, and users can edit existing filters and write their own; Logstash filters are Ruby gems.

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.

CloverDX

CloverDX supports fewer than 20 data sources. Most are various filetypes; databases and Hadoop are also supported. It can write data to databases and files, but it supports no data warehouses or data lakes.

Elastic Logstash

Logstash supports more than 50 log and event data sources. Destinations include Google BigQuery data warehouse, Google Cloud Storage and Amazon S3 data lakes, Elasticsearch, and more than 50 other file formats and operational monitoring platforms.

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.

CloverDX

CloverDX provides support through email and an online ticketing system. Documentation is highly technical. The company provides in-person training services.

Elastic Logstash

Logstash vendor Elasticsearch provides support through a customer-only portal. Logstash is also supported through an open source community. Documentation is comprehensive. Digital training materials are not 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

CloverDX

CloverDX pricing is undisclosed.

Elastic Logstash

Logstash is a free download, and is available bundled with other products in the Elastic Stack as a subscription, which starts at $16 per month. More expensive plans are available that feature things like dedicated support, custom plugins, machine learning, and advanced security features.

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. 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.
