About the Services
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.

Connectors
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.
Supermetrics
Supermetrics allows you to connect to 120+ connectors. The apps list includes sales and marketing platforms, data warehouses, and data lakes. There are only 16 destinations supported. Some popular sources are Google Ads, Facebook Ads, and Google Analytics. Popular destinations are Google Sheets, Looker Studio, and BigQuery.
Note that the pricing depends on the destination. For example, you need to load your data to Excel and then to Snowflake. Each has separate pricing. The pricing plan for each destination limits the number of sources you can connect to. So, you better plan your destination to avoid paying more. For example, instead of loading data to Power BI and Snowflake, use Snowflake only. You can connect any reporting or visualization tool to Snowflake.
If you can't find the needed data source in their list, you can request it. Or you can check their connector roadmap first and see if the missing data source is already under development.
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
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.
Supermetrics
Supermetrics allow you to convert, pivot, sort, and do other transformations. You can do this using Liquid Filters, an open-source template language from Shopify via the Supermetrics API.
Supermetrics provides the data in a denormalized form. It means that combining data doesn’t need relating different tables. Since this tool is for marketers, joining related tables will only confuse them. Supermetrics provide these denormalized data through standard schemas. So, common metrics and data dimensions are ready for use in reports. Users familiar with relatinal data can use custom schemas as well.
Transformations using Liquid will require technical skills. So business users can do transformations in the target reporting platform, like Google Sheets, Excel, or Power BI.
Skyvia
Skyvia is a full-featured ETL service that allows powerful data transformations. It is a no-code solution allowing data splitting, conversion, lookups, and many more.
You can use the Skyvia Data Flow and Control Flow for advanced data pipelines. Transformations for these advanced pipelines are flexible. It supports extending your data with new columns, conditional flows, and summarized values. And all these you can do with parameters, variables, and more for flexibility without code.
Moreover, Skyvia has an Expression Builder to build formulas with many functions. With this, you can convert or extract parts of the data or form new values to suit your needs. And if you love coding in SQL, Skyvia can further extend your transformation needs. It supports multiple joins, groupings, CASE expressions, and more in SELECT queries. And you can also use DML commands like INSERT, UPDATE, and DELETE.
Support
Apache Nifi
Open-source projects like Apache Nifi have communities where you can ask for help. You can be a part of their mailing list or you can chat to them through Slack. There is no resolution time for your problems, neither is priority support.
However, there are how-to videos and documentation. And you can ask questions on developer-focused sites like StackOverflow.
Supermetrics
Supermetrics provides resources for creating ETL pipelines and reports. There are videos, technical documentation, etc. Supermetrics also provides customer onboarding. If this is not enough, you can send a support ticket.
Customer support is a mixed bag in review sites such as G2. Some report good response times, others - longer times. Most of the complaints pertain to bugs mainly resolved by the Supermetrics team.
Skyvia
Skyvia offers free email, chat (on the website or in-app), and forum support for all customers. It also provides extensive documentation with lots of tutorials and user guides.
For paid customers, there's also a phone support option and additional support options for Enterprise customers.
Pricing
Apache Nifi
The tool is free to use, from downloading to configuring. However, keep in mind that you'll have to pay for the planned infrastructure later on. There is no difference whether you'll build your own data centers or use cloud services.
There are also companies offering consulting services and even freelancers who have successful implementations experience, but they also require payment.
So, if you need to get the fast result it will be better to use alternatives that provide quick solutions. Apache Nifi, however, can offer you a flexibility for complex scenarios.
Supermetrics
Supermetrics have fixed-fee pricing depending on the destination of your pipeline. There’s separate pricing for each of the 16 destinations. So, if you need two destinations, you have to pay separately for each. Each destination pricing plan depends on the number of data sources and users. It also depends on how frequently your ETL pipeline runs. So, if you need to have hourly runs for Google Sheets, you need to avail yourself of the Enterprise plan. Data sources beyond your pricing plan require extra payment.
You can avail of the 14-day free trial limited by 100 queries per day per data source. Some users in review sites consider Supermetrics as pricey for its supported features.
Skyvia
Skyvia Data Integration is a freemium tool with an option to request a 14-day trial. So, price is not a barrier to entry.
And when you’re ready, paid plans start from $19 per month. Pricing tiers depend on a few factors. It includes the number of loaded records, scheduling frequency, and advanced ETL features. There are no sale commitments. And customers can upgrade or downgrade at any time. Check out a detailed comparison here.
If you doubt the price is worth it, check out review sites like G2. Aside from ease of use, reasonable pricing is one of the things Skyvia customers like. So, you can be sure the features you get are worth every penny.
