Alooma and Weld side by side: price, connectors and features, where each one is the better choice, and what Weld replaces.
Alooma
WeldAn animation of the migration. Your apps and databases sync through Alooma while Weld's team maps every connector, then both run in parallel into your warehouse until the row counts match, and finally Alooma is switched off while Weld keeps syncing and orchestrates the dbt run after each sync.
Alooma (acquired by Google Cloud in 2019) was a streaming ETL platform that enabled real-time ingestion of data from various sources into BigQuery. Weld puts ingestion, transformations, orchestration and reverse ETL in one product, with 300+ connectors built in house.
You only need managed ingestion into your warehouse, and already run transformations and activation elsewhere.
You want ingestion, transformations, orchestration and reverse ETL in one product, on one bill.
To cover what Weld does, a team running Alooma adds another tool, each set up and monitored on its own.
