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
Celigo
Celigo supports more than 200 connectors. This includes databases, SaaS apps, and more. But your chosen plan limits the number of connectors you can use. The free plan allows you to have 2 endpoints or connectors in 1 flow or integration. You can’t do much in the free plan unless you move to a paid plan.
You can also let Celigo connect to on-premise data sources using the Celigo Agent. With this, there’s no need to whitelist IP addresses from Celigo to your on-premise server.
There’s also a universal adaptor for creating new connectors. So, if your data source can use REST, HTTP, or FTP, Celigo can communicate with it.
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
Celigo
With Celigo, you can sort, group, filter, and more. You can make transformations in 2 ways: using rules or coding in JavaScript.
Celigo allows using rules to define simple operations to transform your data. Some examples are flattening JSON or XML structures or removing columns you don’t want to include in the integration.
But complex transformations require coding. This includes looping through a list to perform a calculation or restructuring the entire row with existing and new columns. So, you need JavaScript skills to do this.
Both rules and JavaScript transformations are available in Flow Builder and Data Loader.
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
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
Celigo
Celigo has many online resources and the community. There is also free online training at Celigo University and live training sessions from experts. Aside from these, Celigo has a support system in their Customer Success Plans. There are 3 plans: Essential, Preferred, and Premier.
Customers of any plan have access to online resources, support tickets, and chat. They also have a customer success manager.
Standard support SLA is available for the Essential plan. Meanwhile, phone support and extended hours are available for the Preferred plan. Finally, the Premier plan adds the highest support SLA. It includes the fastest response time and strategic planning.
Whether these plans are part of any of the pricing plans is not clear. Contact their Sales representative to clarify.
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.
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, Skyvia offers a prioritized support including additional support options for Enterprise customers.
Pricing
Celigo
The pricing plans for Celigo are available in G2. They are Free, Professional, Premium, and Enterprise. What you can get for each plan is available but not the price. You have to contact Sales to get a quote.
You can start with the 30-day free Ceiligo trial with all features accessible. Except that you can’t use the Sandbox environment where you can test your integrations. When the trial period expires, you need to upgrade to a paid plan or you will be switched to the Free plan where you can only have 1 flow integration and 2 endpoint with no Celigo Agent for on-premise data sources.
Choosing a paid plan will allow you to have more endpoints, flows, and access to API management. But for Professional and Premium plans, the API management is a separate price. Note also that the integrator.io Sandbox has a license with a separate price.
Celigo pricing is one of the dislikes in review sites. But some agree that you get what you paid for.
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.
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.
