OPEN-SOURCE DATA WORKFLOW ORCHESTRATION

Love your workflows again

Welcome to our second-generation open source orchestration platform, a completely rethought approach to dataflow automation.

Welcome to 'workflows as code.' Write dataflows naturally right inside standard Python functions.
PRODUCTIVITY
Code as Workflows

If Python can write it, Prefect can run it.

Finally, flows as flexible as you need them to be. If Python can write it, Prefect can run it.
FLEXIBILITY
Dynamic Workflows

Finally flows as flexible as you need them to be: generate any task at runtime.

Automate workflows, Supercharge your pipelines and make them smarter with granular scheduling, dependencies, parameters, and more
ORCHESTRATION
Batteries Included

Everything you need for a complete orchestration platform.

Integrate tools, Connect it all with a broad library of pre-built integrations.
VISIBILITY
Reimagined UI

Customize your view of your stack.

01

Code as Workflows

Turn any function into a task or flow. If Python can write it, Prefect can orchestrate it.

Continuous Workflows

Use for or while loops to create infinitely-long flow runs, no schedule required.

Event-Based Workflows

Trigger flows from external events such as file or system updates.

Versioning

Know when flow code changes so that you can quickly diagnose and resolve failures.

Asynchronous Task Support

Run concurrent tasks independently so flows can run faster and elegantly handle blocking.

Streaming Support

Launch new flow runs in response to events from streaming systems or message queues.

Fewer failures. More peace of mind.
02

Goodbye, DAGs

Design dynamics workflows that generate tasks at runtime, for more use cases with less code.
