Workflow Builder

Chain lab tools on a canvas: each node’s outputs become typed context for the next ones, validated as you build.

How to use

1. In the catalog, open an example to run it or create a new workflow. In the editor, use Add node and connect the nodes from Start: solid lines set the execution order.
2. Set where each input comes from: connect an output to an input on the canvas (dashed line) or pick in the inspector a workflow input, an output of an earlier node, or a value asked during the run.
3. Watch the problems panel: incompatible types, references to another branch, and inputs that will be asked during the run show up as you edit.
4. Click Run: the run pauses to ask for missing values and shows the context and result of every node.
5. Save the workflow in your browser: it shows up in the catalog and opens in view mode, without the editing tools. Export the JSON to take it elsewhere.

Good to know

• Ready examples in the catalog: emails, dates and domains in a text, unique sorted emails, cited domains, dates of a year, active user names from a JSON, validate JSON and branch, a field of a YAML and a JSON fingerprint.
• Each node declares typed inputs and outputs; outputs go into the context, so the shape of the available data is known at every point of the flow.
• Conditions split the flow into branches; each branch only sees the context of its own path.
• Everything runs locally: workflows stay in your browser and nothing is sent to servers.
