DAGs: Classic Workflows - Synthreo Pylon
How the classic node workflows live on in Pylon as DAGs - create one from DAGs or Templates, use the same canvas, and know when to use an Agent instead.
What you’ll accomplish
Section titled “What you’ll accomplish”If you built node workflows in Builder, you already know DAGs - this page maps the classic experience onto Pylon so you can keep building without missing a step.
What a DAG is
Section titled “What a DAG is”A DAG (directed acyclic graph) is the classic node workflow: you place nodes on a visual canvas, wire them together, and data flows through exactly the path you drew. Same canvas, same nodes, same behavior as the classic Builder workflow - Pylon renames the object and gives it a dedicated home.
Choose a DAG for fixed, repeatable pipelines; choose an Agent when the work is open-ended and the AI should decide the steps.
Creating a DAG
Section titled “Creating a DAG”- In the left navigation under Build, select DAGs, then Create DAG.
- Give it a Name (the characters
/ # ? % $aren’t allowed) and select Create DAG. You’ll land on the visual canvas. - Build as you always have - nodes, connections, test, publish. The node-by-node reference lives in the Pylon documentation.
Prefer a head start? Build → Templates offers prepared workflows: “Choosing a template creates a new DAG and loads it onto the canvas.”
Where DAG things moved
Section titled “Where DAG things moved”| You’re looking for | In Pylon |
|---|---|
| Your workflows | Build → DAGs (archived ones under the Archived toggle) |
| Prepared workflows | Build → Templates |
| Run monitoring | Monitor → Dashboard and Monitor → Activity |
| Usage statistics | Insights → Analytics (the page is titled Statistics; DAGs have their own tab) |
| Exposing DAGs as tools | Via an MCP server. Note the server itself is created in Canopy, not Pylon: the standalone MCP Server Builder page was removed from Pylon and its URL now redirects. Canopy-built servers still appear in Pylon’s embedded picker, because the two share one backing store |
| Website chat embed | Deploy → Integrations → Websites, plus the Website widget tab when publishing a DAG |
Plan limits
Section titled “Plan limits”Agents and DAGs are metered against one shared quota, so reaching the cap blocks both. The two create buttons word it differently - Create DAG says “You have reached your DAGs plan limit. Upgrade your subscription to create more.” and the Agents button names agents - but there is a single counter behind them. Building a DAG is not a way around an exhausted Agent allowance.
