Visual JSON Pipeline Builder

Build a visual JSON data pipeline in your browser by connecting input, transformation, filtering, and export nodes. Run a workflow locally and inspect data between steps; an API Fetch node can also request a URL you configure.

Key Features

Node-based DAG workflow editor powered by React Flow
Sequential execution engine for predictable data flow
Integration with Transform Builder and Mock API systems
Drag-and-drop node palette for easy workflow building
Real-time execution status and data previews on connections
Workflow definitions and local data processing stay in your browser

Privacy & Security

Pipeline steps run in your browser. If you add an API Fetch node, your browser requests the URL you configure.

Large Dataset Support

Processing time and available file size depend on the input and your browser's memory and processing capacity.

Frequently Asked Questions

Where does a pipeline run?

Pipeline nodes execute in the browser. If you add an API Fetch node, the browser makes a request to the URL you configure and passes its response into the workflow.

How does execution work?

Workflows are executed sequentially following a Directed Acyclic Graph (DAG). Each node waits for its predecessors to complete before processing the combined data stream.

How are pipelines saved?

You can save a pipeline in your local browser workspace or share a link containing a copy of the workflow and its input data. The shared link does not include generated results.
