I like how it transforms data from multiple databases into a single, resolvable, SQL-like dataset, including data coming from NoSQL databases.

What I appreciate most about Fivetran is that it's a no-code platform. During setup, there's no need to write custom logic for incremental loads, schema drift handling, or ingestion tuning — these are all pre-built and handled out of the box. Post-configuration, the platform is largely self-monitoring: silent failures are eliminated since you're automatically alerted when a source system goes down, and most of the pipeline runs without manual intervention. It also offers ready-made connectors for the majority of widely-used software tools, which significantly reduces integration overhead.

I like their UI and the variety of available connectors. They’re really easy to set up, even if you have limited technical knowledge.
