Features

Set up once. Weld keeps it running.

Replication modes, schema changes, alerts and logs, handled in one place for every source.

Every replication mode

Incremental, full or CDC, picked per table, with history tables when you need a full audit trail.

modeincremental · full · cdc

Schema changes handled

Schema migrations and API versions are handled for you, and a failed run retries with exponential back-off.

Capture deletes

Keep the rows a source stops returning, stamped with the time they disappeared, instead of losing them on a full sync. In beta.

Alerts where you work

Route alerts to Slack, email or webhooks by severity and pipeline, so the right person hears first.

alert#data-alerts · stripe.charges failed

Logs for every run

Sync history, row-level logs and data volumes: when each table synced, how long it took and how much moved.

last runshopify.orders · 1,204 rows · 38s

Orchestrated with the rest

Chain syncs with transformations on a schedule you set, and trace lineage from source to dashboard.

Replication modes

One change at the source. Three ways to land it.

Pick the mode per table. Change data capture is the one that sees every delete.
