Move your event data in real time
Stroomflow is the streaming platform engineering teams use to ingest, transform and route events — from source to destination in milliseconds, with no pipelines to babysit.
# Create a stream and start pushing events import stroomflow client = stroomflow.Client(api_key=os.environ["SF_API_KEY"]) stream = client.streams.create(name="orders", format="json") stream.publish({"order_id": 4815, "total": 162.40}) # Subscribe downstream over a persistent connection for event in stream.subscribe(group="warehouse"): warehouse.upsert(event)
Built for data teams operating across the EU
Platform
Everything you need to run streaming data
One platform for ingestion, processing and delivery — so your team ships data products instead of maintaining brokers.
Real-time ingestion
Push events over HTTP, WebSocket or our SDKs. Millions of messages per second with back-pressure handled for you.
Transform in-flight
Filter, enrich, mask and reshape streams with SQL or JavaScript — no batch jobs, no copies at rest.
Route anywhere
Deliver to warehouses, lakes, queues and webhooks with exactly-once guarantees and automatic retries.
Built-in observability
Live throughput, lag and error metrics for every stream, plus alerting that fits your on-call.
60+ connectors
Postgres, Kafka, Kinesis, Snowflake, BigQuery, S3 and more — connect sources and sinks in minutes.
Secure by design
End-to-end TLS, per-stream access keys, audit logs and data that never leaves the EU.
How it works
From source to destination in three steps
No clusters to size, no Zookeeper to operate. Connect, transform, deliver.
Connect a source
Point Stroomflow at a database, queue or app event stream, or push directly with an API key.
Shape the stream
Define transformations once. They run continuously as data flows, versioned and observable.
Deliver in real time
Fan out to every destination your teams depend on, with delivery guarantees you can trust.
