About the Services
Hevo
Hevo is a no-code, low-code data movement platform that handles ETL, ELT, and Reverse ETL. It launched in 2017 and today, more than 2500 organizations trust Hevo. This includes Abbot, Hugo, and more.
The Hevo Pipeline UI uses a simple fill-in-the-blanks form. And from here you can specify the sources, transformations, and destinations. Meanwhile, you still have the option to reverse ETL using Hevo Activate. It supports 150+ connectors but the number of destinations is 15+ only. Reviewers from sites like G2 wish there were more destinations.
You can start with Hevo for free. But it limits the connectors you can use to 50+.
Hevo complies with data privacy and security standards. They have certifications for SOC2, GDPR, HIPAA, and CCPA. But only the Business pricing tier ensures HIPAA compliance.
Apache Nifi
Apache Nifi is an open-source, easy-to-use system to process and distribute data. Brand new UI version 1 was released in 2016. More than 2400 companies are using Apache Nifi, according to Enlyft.
Apache Nifi works on-premise or with any cloud provider. You can download, install, and configure Apache Nifi on Linux, Mac, and Windows machines. Keep in mind that Nifi may require technical skills. You can’t install it and build ETL pipelines in minutes. But once you complete your configuration, you can prepare data pipelines in a browser.
There are no limits on the number of data sources and destinations in a pipeline. You are only limited by the processing capacity of your machine.
Data security and privacy are your responsibility. But if you deploy the system in AWS or Azure, you can leverage their security and privacy certifications.

You can add more sources not listed in Hevo if those sources use REST API. Otherwise, you need to reach out to Hevo support to request your unlisted source.
Apache Nifi
Apache Nifi can connect to various data sources, including SQL and NoSQL databases, flat files, and others. It has a number of components for data extraction and loading called processors which you can drag in the Nifi canvas and configure.
Every Nifi processor for data access is available to you. You can check the Apache Nifi documentation for more details.
You can contribute new data sources and destinations to the сommunity. So, you need to know Java and follow the rules of the community in contributing code.
Skyvia
Skyvia offers more than 180 connectors, and more to come very soon. It supports connectors for CRMs, accounting, email marketing, e-commerce, human resources, marketing automation, payment processing, product management, all major databases and DWH, flat files, and more. It’s also not a problem whether your data is on-premise or in the cloud.
You can access your on-premise data with peace of mind using the Skyvia Agent. It allows you to connect to databases like SQL Server, MySQL, and more using an encrypted connection. You need to download the Skyvia Agent and install it. Then, download a secured key file and place it in the same folder as the Agent. The Agent is like an unbreakable metal door, and you use the key file to open that door to your on-premise data. You can also set it up so that Skyvia can access only the resources you specify and nothing else.
Customers can also leave a request for a new data connector. And Skyvia will prioritize building it without additional payment.
Transformation
Hevo
Hevo Pipelines supports 2 ways to create transformations. First is the Python-based transformations. So, you need Python coding skills to do this. Another option is the drag-and-drop transformations. Both ways of transformation support aggregating, cleansing, filtering, and more. These are user-driven transformations.
Automatic transformations occur in Hevo before it reaches the destination. This includes table and column name sanitizing, date conversion, and more. Note that Hevo always converts dates and times to UTC format. So, if you use a different time zone, you might get surprised with this conversion.
Hevo also supports post-loading transformations. This happens when you already loaded your data in the destination. When you need post-loading transformations, Hevo requires you to use SQL models.
For more advanced transformations, Hevo also supports dbt transformations.
Apache Nifi
Apache Nifi transformation capabilities include aggregating, splitting, data encryption, and decryption to hide sensitive information. You can also do XSLT transforms for XML data and JOLT transforms for JSON data. Besides that, you can also do regular expressions and even run SQL commands in relational databases.
All transformations in Apache Nifi are part of its Processors list. So, check specific transformation processors in the Apache Nifi documentation.
Skyvia

And you can also use DML commands like INSERT, UPDATE, and DELETE.
