// Capabilities
Everything your pipelines need, in one plane
Ingestion, routing and monitoring — three systems that usually fight each other, finally speaking one protocol.
Stream-Safe Security
Field-level masking, end-to-end encryption and immutable audit trails on every event — compliance without the config tax.
Learn moreLive Insights
Throughput, lag and cost per stream rendered in under a second. Alert on anomalies before your users ever feel them.

From source to signal in three moves
A single glowing circuit from raw events to decisions your team can act on.
01 · Connect
Connect your sources
Point Flow at any database, queue or event stream. Autodiscovered schemas and managed backfill keep history intact.
02 · Route
Route & transform
Branch, filter, enrich and reshape events in flight — with a visual DAG or raw SQL, whichever your team prefers.
03 · Observe
Monitor & optimize
Live dashboards, anomaly alerts and auto-scaling keep every stream inside its latency budget, around the clock.

Teams that stopped babysitting pipelines
“Flow cut our pipeline latency from 40ms to 6ms in a weekend. We stopped babysitting infrastructure and started shipping analytics.”
Mara Chen
Head of Data, Helio Labs
“The first platform where the monitoring is as sharp as the routing. Our on-call pages dropped 70% in the first month alone.”
Devon Park
Staff Engineer, Vector Grid

Frequently asked questions
What exactly does Flow do?
Flow is a real-time data-pipeline platform: it ingests events from your sources, routes and transforms them in flight, and monitors throughput, lag and cost across every stream — at sub-8ms p99 latency.
How is my data secured?
Every event is encrypted in transit (TLS 1.3) and at rest (AES-256). Pipelines support field-level masking, role-based access and immutable audit logs, and Flow is aligned with SOC 2 Type II controls.
What are the free-tier limits?
Initiate includes 2 active pipelines, 1M events per month and 7-day retention — free forever, no credit card required. Upgrade to Flow Pro anytime to lift the limits without re-building a thing.
