Swimlane Diagram Software
Model swimlane diagrams where every task belongs to a role and every handoff is visible. Native BPMN 2.0 pools and lanes, real-time collaboration, AI discovery, and standards-compliant export. Free, in your browser.
Lanes that mean something
In most tools, swimlanes are just boxes. In Crismo they are real BPMN 2.0 elements, so who does what - and where work hands off - is part of the model.
- Native pools and lanes
- Swimlanes are first-class BPMN 2.0 elements in Crismo, not shapes you fake with rectangles. Drag a lane, drop tasks in, and responsibility is captured in the model.
- Assign every task to a role
- Each lane is a role, team, or system. Every task sits in exactly one lane, so who does what is unambiguous the moment you look at the diagram.
- See every handoff
- When work crosses a lane boundary, the handoff is visible - the single most common source of delay and miscommunication. Spot bottlenecks at a glance.
- Real-time collaboration
- Build the diagram with the people in each lane on the same canvas. Cursors, comments, and edits sync instantly - no emailing files around.
- Standards-compliant BPMN 2.0 export
- Your swimlane diagram is valid BPMN 2.0 XML. Hand it to Camunda, Flowable, or any compliant engine. No proprietary lock-in.
- AI-powered process discovery
- Describe the process in plain language or paste a transcript, and AI drafts the lanes and tasks so you start from a first draft, not a blank canvas.
Every task in a lane, every handoff visible
A swimlane diagram assigns each task to the role that owns it. Where the active task jumps between lanes, that is a handoff - the usual home of delay and dropped work.
A support-ticket process across three lanes. Watch the work hand off Customer → Support → Engineering → Support → Customer. In Crismo these lanes are native BPMN 2.0 elements.
How swimlane diagrams work in Crismo
Lanes that carry meaning, not just visual boxes.
- 1
Add a lane per role
Drop in a pool and split it into lanes - one per role, team, or system. Lanes are native BPMN 2.0 elements in Crismo, so the model captures ownership, not just a visual container.
- 2
Place each task in its lane
Every task sits in exactly one lane, so responsibility is unambiguous. As you sequence the flow, each time it crosses a lane boundary Crismo makes the handoff explicit - the exact spots where work waits or gets dropped.
- 3
Collaborate, then export
Build it live with the people in each lane, then export standards-compliant BPMN 2.0 XML for Camunda or any tool. The responsibilities travel with the file - no lock-in.
Worked example
The support-ticket flow above has four handoffs across three lanes. The diagram makes the risky one obvious: when Support hands off to Engineering, a ticket can sit for days with no owner. Put both roles in lanes and the gap is visible at a glance - which is the whole point of a swimlane, and why the lanes need to mean something, not just look right.
