Fivetran, Airbyte, Stitch, and HevoData work from closed, pre-built connector catalogs — if the source you need isn't in the catalog, you wait. rsync.ai generates the connector on demandfrom any API's docs: source-available so you can read or fork it, and flat-priced so a backfill never spikes your bill.
Instead of waiting for a vendor to add a source to a catalog, rsync.ai generates the connector from the API's docs — as source-available code you can read, audit, or fork.
Point rsync.ai at any REST or GraphQL API documentation and it produces a working connector in minutes. No waiting for a vendor to add it to a catalog.
Every generated connector is readable code under the Elastic License 2.0. Read it, audit it, or fork it. Fivetran and Stitch connectors are closed — you never see the code.
The pipeline discovers the schema, detects PII, plans the sync, and asks for your approval before it runs — no YAML to write, no connector UI to wire up.
Including where competitors are still ahead — we believe honest beats impressive.

How you get billed matters as much as the sticker price. Per-row and per-MAR models spike unpredictably.
rsync.aiyou
Flat GB / month
Predictable — a backfill that moves a billion rows costs the same as one that moves a thousand.
Fivetran
Per Monthly Active Row (MAR)
Spikes on backfills, schema changes, or high-churn sources. Hard to forecast.
Airbyte
Per-MAR (Cloud) / Free (self-host)
Cloud plan spikes like Fivetran. Self-host is free but you own all ops.
Stitch
Per row synced
Costs scale directly with row volume — every backfill hits the bill.
HevoData
Per event
Event-level billing makes high-frequency sources expensive fast.
