Fivetran, Airbyte, Stitch, and HevoData work from pre-built connector catalogs — if the source you need isn't in the catalog, you wait. rsync.ai generates the connector on demand from any API's docs, billed on data volume, not per row or Monthly Active Row — with source-available connector code to read or fork coming soon.
Instead of waiting for a vendor to add a source to a catalog, rsync.ai generates the connector from the API's docs in minutes — with source-available code to read, audit, or fork coming soon.
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 will be readable code under the Elastic License 2.0 — read it, audit it, or fork it when self-hosting ships. 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 — billed on GB moved, not per row or MAR. Pipelines pause at your GB cap instead of running up a surprise overage.
Fivetran
Per Monthly Active Row (MAR)
Spikes on backfills, schema changes, or high-churn sources. Hard to forecast.
Airbyte
Volume-based credits (Cloud) / Free (self-host)
Cloud bills on data volume (per GB / per million rows), so backfills still add cost. 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.
