What is Airbyte

An open-source data integration platform, Airbyte is a popular choice for those building a modern data stack. Airbyte boasts its collection of ELT connectors as well as the ability to build custom ones in the platform, a differentiator from other no-code ELT tools. Because building custom pipelines requires coding knowledge, this special feature will only benefit data specialists with solid coding abilities. Airbyte is built to work well with DBT and SQL, so this is an important thing to note before deciding to use the tool.

Pros

  • Open-source platform
  • A really large number of connectors and destinations
  • Easy deployment
  • Managed cloud option
  • Engineering-focused with advanced options to build your own connectors and features
  • Has both ELT and Reverse ETL options
  • Large community

Cons

  • More suited for advanced teams
  • Require more maintenance
  • The quality of connectors can vary because of open-source
  • High dependence on community

What I like about Airbyte

If you don't have workloads that currently use DBT or fit well into that model, this probably isn’t the tool for you.

What is Meltano

Meltano is another open-source data integration platform like Airbyte that is designed to help businesses build their own data integration pipelines. The platform provides users with a wide range of integration options, including connectors for databases, APIs, and application logs. Additionally, Meltano provides extensive support for data transformation and orchestration and integrates well with several cloud-based data warehouses.

Pros

  • Open-source platform
  • A really large number of connectors through Singer
  • Offer an SDK to more easily build Singer taps and targets

Cons

  • No fully managed options so you need to deploy yourself (in Beta though)
  • Requires high maintenance
  • Limited data transformation capabilities (only through deep integration with DBT)
  • Only has a limited number of connectors that are natively built outside of Singer

As a user on G2 puts it::

What I like about Meltano

The best thing about Meltano is that it's simple and easy to use. It's portable, so I can run it on the command line, or in a docker container, or in any number of orchestration tools.

A reviewer on G2 said:

What I like about Weld

First and foremost, Weld is incredibly user-friendly. The graphical interface is intuitive, which makes it easy to build data workflows quickly and efficiently. Even with little experience in SQL and pipeline management, we found that Weld was straightforward and easy to use. What really impressed me, however, was Weld's flexibility. It was able to handle data from a wide variety of sources, including SQL databases, Google Sheets, and even APIs. The solution also allowed us to customize my data transformations in a way that best suited my needs. Whether I needed to clean data, join tables, or aggregate data, Weld had the necessary tools to accomplish the task. Weld's performance was also exceptional. I was able to run large-scale ETL jobs quickly and efficiently, with minimal downtime via a Snowflake instance and visualization via own-hosted Metabase. The solution's scalability meant that I could process more data without any issues. Another standout feature of Weld was its support. I never felt lost or unsure about how to use a particular feature, as the support team was always quick to respond to any questions or concerns that I had. Overall, I highly recommend Weld as an ETL solution. Its user-friendliness, flexibility, performance, and support make it an excellent choice for anyone looking to streamline their data integration processes. I will definitely be using Weld for all my ETL needs going forward.

What I dislike about Weld

Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.
