Top 5 Paid and Open-Source ETL Tools [2021]

Data generation is increasing rapidly, and so is the need to tame this gigantic beast into a usable form — for all business users.

A common methodology used for this purpose is ETL: Extract, Transform and Load. The ETL tools market itself is slated to grow from $8.5 billion in 2019 to $22.3 billion in the next seven years.

The very essence of this revolutionary market is based on a series of trends — from cloud platforms to new forms of data and other types of SaaS-based tools. Depending on the type of data stored within their data warehouse, their resident skill sets, and their budget, organizations can choose between different ETL tools to manage their data manipulation and transformation needs.

Here’s a list of the most prominent ETL tools.

Top 5 ETL Tools

1. Kloudio

2. Informatica Power

3. Talend Open Studio (TOS)

4. Stitch

5. Oracle Data Integrator (ODI)

1. Kloudio: Redefining The Power of Spreadsheets

As the name spells out, Kloudio is one of the best cloud-based startups. 

Its ETL capabilities offer resourceful tools for data retrieval, reporting, and transformational processes.

2. Informatica PowerCenter: Power Large Organizations Efficiently

Established in 1993, Informatica offers a multitude of integration services, including ETL, iPaaS, API management, and cloud management. Many large-scale organizations use this platform for its multi-varied connection and integration capabilities.  

Large organizations tend to look for ETL tools that can access data in the cloud. PowerCenter is one such tool and  consists of four primary components, namely:

  • Workflow manager
  • Monitor
  • Designer
  • Repository manager

To complete the ETL process, a data engineer needs to use all of these processes in a structured manner, which can lead to roadblocks. Undeniably, PowerCenter is a complex ETL tool. Data engineers should undergo extensive training and certifications conducted by Informatica University to use this tool.

While talking about Informatica’s suite of products, it wouldn’t be fair to miss Informatica Cloud Data Integration (ICDI). Optimized for app integrations, ICDI caters to many cloud-based APIs as an ETL replacement with its pre-built connectors. This tool is user-friendly and offers basic data transformation capabilities.

ICDI does a decent job with high volume extracting and loading operations; nevertheless, its data transformation capabilities are restricted. If your needs are extensive and ETL requirements are heavier than usual, it’s best to steer away from Informatica’s products.

Informatica PowerCenter is expensive software, whereas ICDI is one of the more economical offerings by Informatica.

3. Talend Open Studio (TOS): Open to The World

Another popular open-source application is the Talend Open Studio data integration software. The company is well known for its range of diversified software services for data integration and management. Considered to be a dominant force in the ETL tools market for Big Data, TOS is listed as a proficient provider for the following suite of services also:

  • Cloud integration
  • Data integration
  • Big Data integration
  • Data quality
  • Data preparation

The interface consists of three panes: Repository, Component Palette, and Design Workspace.

The Repository holds data pertaining to items in the process of designing jobs. A Component, on the other hand, can be regarded as a preconfigured connector required for pre-defined data integration operations. This is dragged into the Design Workspace, where you can lay out and design jobs for execution.

Another advantage of this tool is its multi-faceted approach to connecting with different data sources like files, databases, SAP, Salesforce, FTPs, and more. Once data is read from any of these sources, it can be pushed into different databases like Azure, Oracle, and MSSQL Server if needed.

4. A “Stitch” in Time, Saves Nine

If silos are troubling you, then it’s time to break down the barriers and let data flow freely. 

But, how? Data is a confidential element and can be used by anyone, especially if not shared properly. This is where ETL comes into the picture. By following the methodologies of ETL, a service provider like Stitch can literally stitch up the loose ends and create a well-crafted data fabric.

Stitch is well equipped to connect to different databases like MongoDB, MySQL, and SaaS tools like Zendesk and Salesforce. Its data pipelines are constructed in a way to transfer data from one end to another in a matter of minutes.

As an ETL platform, Stitch comes with no strings attached — it has no API maintenance costs, scripting hassles, and JSON wrangling issues.

Here are some other advantages:

  • It’s a simple and clean tool, but its simplicity does not bog down its powerful ETL capabilities
  • You can connect to a multitude of data sources
  • It’s an open-source tool, making it easier to procure and use
  • It includes features related to automated monitoring and alerting
  • You own your data infrastructure, without worrying about leasing and renting from third-parties

In the end, Stitch is a tool with a mature replication engine, which values multiple strategies and fills up your repository with data from Amazon Redshift, Google BigQuery, and more. It complies with all security regulations, often required while transferring data from one data source to another.

5. Oracle Data Integrator (ODI): Looking Into the Future

Oracle Data Integrator is a well-endorsed data integration solution for existing Oracle users, especially those who are using Hyperion Financial Management and Oracle E-Business Suite (EBS).

Oracle, as a service provider, offers a cloud version (Oracle Data Integration Platform Cloud) and an on-premise option (Oracle Data Integrator). ODIPC offers pre-built connectors for SaaS applications and is a renowned developer for providing fast performance within a browser-based interface.
