Side by side

What it does

A workflow tool for running repeatable team processes such as onboarding and approvals from templates, with task assignment and human-in-the-loop steps.

A self-hosted workflow suite with a BPMN modeler, a screen builder for forms, assignment and routing rules, task due dates and request history.

Watch out

Open-sourced only in late 2024, and self-hosting needs Postgres, Redis and RabbitMQ.

Several packages, saved searches among them, are not in the open-source edition, and there is no stage board.
