Meltano and Weld side by side: price, connectors and features, where each one is the better choice, and what Weld replaces.
Meltano
WeldAn animation of the migration. Your apps and databases sync through Meltano while Weld's team maps every connector, then both run in parallel into your warehouse until the row counts match, and finally Meltano is switched off while Weld keeps syncing and orchestrates the dbt run after each sync.
Meltano is an open-source data integration and orchestration platform built around the Singer ecosystem. Weld puts ingestion, transformations, orchestration and reverse ETL in one product, with 300+ connectors built in house.
You need the widest connector catalog (600+ against 300+).
You want ingestion, transformations, orchestration and reverse ETL in one product, on one bill.
To cover what Weld does, a team running Meltano adds another tool, each set up and monitored on its own.
