Scale data pipelines
without rebuilding them

Move billions of records across systems with sub-second latency, exactly-once delivery, and per-record observability — without rewriting your stack.

Adopted by fast-scaling companies moving mission-critical data in real time

Where pipelines break at scale

Three reasons your data pipeline breaks at the next 10x.

The pipeline that worked at 1M records/day starts dying at 100M. Most rebuilds happen for the same three reasons.

01 — Backpressure

Source systems can't keep up with downstream processing

Your warehouse can ingest at 100k records/sec; your CRM API caps at 100/sec. Without intelligent backpressure, queues balloon and the slowest connector starves the rest.

THROUGHPUT
02 — Replay & lineage

When a pipeline drops a window, you lose three days finding the gap

Most pipelines log success or failure but not what was processed. Recovering from a partial outage means writing a one-off backfill script — and crossing your fingers that it doesn't double-write.

RELIABILITY
03 — Schema evolution

Every upstream change is a downstream incident

When Salesforce adds a field or Stripe deprecates an endpoint, your pipeline silently drops the new data and you find out a week later from a confused dashboard.

COUPLING
PLATFORM

Six products. One Platform.

Securely connects to your systems with:

What throughput can Stacksync sustain?

Production deployments routinely sustain 100k+ records/second per pipeline, with horizontal scaling for higher loads. The platform is tested at 1M+ records/second on stress fixtures.

How is exactly-once delivery guaranteed?

Stacksync uses idempotency keys per record and transactional outbox patterns at sinks. Replays of any window are safe — duplicates are dropped at the sink.

What happens when an upstream schema changes?

Schema changes are detected on every sync. New fields appear automatically; removed or renamed fields trigger a Slack/email alert with the affected mappings, before the next sync runs.

How do we replay a missed window?

Every sync run is durable with a per-record manifest. Click 'Replay' on a window in the UI; Stacksync re-runs the failed records (deduped by idempotency key) without touching the records that succeeded.
