Technical Lead & BPMN Educator·12 min read
Not every tool that has BPMN shapes produces valid BPMN. Some generate standards-compliant XML that process engines can execute. Others draw pretty pictures that look like BPMN but export as proprietary formats. That distinction matters the moment you need to validate, automate, or share your models across tools.
We evaluated each tool on five criteria: BPMN 2.0 compliance (does it export valid XML?), collaboration (can a team work together?), ease of use, ecosystem and integrations, and pricing.
"If you are just starting with BPMN, pick any tool from the “Full BPMN 2.0” row in the comparison table below. You can always switch later because valid BPMN files are portable across tools. That is the whole point of the standard."
Quick Comparison
| Tool | Valid BPMN 2.0? | Collaboration | Free Tier | Best For |
|---|---|---|---|---|
| Camunda | ✅ Full | Limited | ✅ Community | Process automation |
| SAP Signavio | ✅ Full | ✅ Multi-user | ❌ | Enterprise BPM |
| ARIS | ✅ Full | ✅ Multi-user | ❌ | Multi-notation (EPC+BPMN) |
| Bizagi | ✅ Full | ✅ Cloud | ✅ Desktop | Free desktop modeling |
| bpmn.io | ✅ Full | ❌ | ✅ Open source | Quick sketches, embedding |
| Crismo | ✅ Full | ✅ Real-time | ✅ Unlimited | Team collaboration |
| Trisotech | ✅ Full | ✅ Multi-user | ❌ | BPMN + DMN + CMMN |
| draw.io | ❌ Shapes only | Via Drive | ✅ | Quick informal diagrams |
| Lucidchart | ❌ Shapes only | ✅ Real-time | Limited | Cross-functional visuals |
| Visio | ❌ Shapes only | Via SharePoint | ❌ | Microsoft ecosystem |
“Valid BPMN 2.0” means the tool exports XML that conforms to the OMG BPMN 2.0 specification and can be imported by any compliant tool or process engine.
The BPMN Compliance Divide
The most important distinction in this list is not price or features. It is whether the tool produces real BPMN 2.0 XML or just draws shapes that look like BPMN.
Tools that produce valid BPMN 2.0 (Camunda, Signavio, ARIS, Bizagi, bpmn.io, Crismo, Trisotech) give you files that any other BPMN tool can open. You can validate them, simulate them, and feed them to process engines for automation. Your work is portable.
Tools that draw BPMN shapes (draw.io, Lucidchart, Visio) give you proprietary files that look correct on screen but cannot be imported by other BPMN tools, validated for structural correctness, or executed by process engines. Your work is locked in.
If you are doing process documentation that will only ever be viewed as a picture, the distinction does not matter. If you plan to validate, automate, migrate, or scale your process models, it matters enormously. Read BPMN vs Flowchart for more on why this distinction exists.
Tool-by-Tool Breakdown
Camunda
Process AutomationBPMN Compliance
Full BPMN 2.0 with execution
Collaboration
Modeler is single-user, Optimize has dashboards
Pricing
Community Edition free, Enterprise pricing on request
Best For
Developer teams building executable BPMN processes
Strengths
- +Strongest process execution engine on the market
- +Open-source community edition available
- +Large ecosystem of connectors and integrations
- +Active developer community
Limitations
- -Modeler is basic compared to dedicated modeling tools
- -Steep learning curve for non-developers
- -Enterprise version is expensive
Our take: The gold standard for process automation. If your goal is to execute processes, Camunda is hard to beat. For pure documentation and modeling, other tools offer better experiences.
SAP Signavio
Enterprise BPMBPMN Compliance
Full BPMN 2.0
Collaboration
Multi-user with approval workflows
Pricing
Enterprise pricing (typically $30k+/year)
Best For
Large organizations with dedicated process teams
Strengths
- +Process mining integration (Celonis acquisition)
- +Governance workflows with approval chains
- +SAP integration for ERP-connected processes
- +Process repository with versioning and audit trails
Limitations
- -Very expensive, not accessible for SMBs
- -Heavy, complex interface with steep learning curve
- -SAP acquisition has shifted focus toward SAP ecosystem
Our take: The enterprise heavyweight. Excellent for organizations with 500+ employees and dedicated process teams. Overkill for smaller teams or anyone not in the SAP ecosystem.
ARIS
Enterprise BPMBPMN Compliance
Full BPMN 2.0 plus EPC and other notations
Collaboration
Multi-user with role-based access
Pricing
Enterprise pricing (similar to Signavio)
Best For

- +Strong governance and compliance features
- +Large installed base, especially in DACH region
Limitations
- -Interface feels dated compared to modern tools
- -Expensive and complex to deploy
- -Cloud offering still catching up to competitors
Our take: The legacy enterprise standard. If your organization already uses ARIS or needs EPC notation alongside BPMN, it is hard to replace. For greenfield projects, newer tools offer better UX.
Bizagi
Process Modeling + AutomationBPMN Compliance
Full BPMN 2.0
Collaboration
Cloud version has multi-user editing
Pricing
Free desktop modeler, cloud plans from $0-$500/month
Best For
Teams that want free modeling with optional automation
Strengths

- +Path to automation (Bizagi Automation Server)
Limitations
- -Free modeler is desktop-only (Windows/Mac, no web)
- -Cloud version has limited free tier
- -Automation features require significant investment
Our take: The best free desktop BPMN modeler. If you work on Windows/Mac and want a full-featured modeler at zero cost, Bizagi Modeler is excellent. The cloud story is less compelling.
bpmn.io
Open Source ModelingBPMN Compliance
Full BPMN 2.0 with XML
Collaboration
None (single-user, browser-based)
Pricing
Free and open source
Best For
Quick sketches, learning BPMN, embedding in your own applications

- +Open source, embeddable in custom apps
- +Maintained by Camunda
Limitations
- -No collaboration features
- -No process landscapes or organizational views
- -No cloud storage (local files only)
- -Minimal validation beyond basic syntax
Our take: The quick-start choice. Perfect for learning BPMN, creating a single diagram, or embedding a modeler in your own application. Not designed for team use or process management.
draw.io (diagrams.net)
General DiagrammingBPMN Compliance
BPMN shapes only, no BPMN 2.0 XML export
Collaboration
Via Google Drive or Confluence
Pricing
Free (Atlassian marketplace paid)
Best For
Quick informal diagrams, Confluence/Jira integration
Strengths
- +Free with no limits
- +Tight Confluence and Jira integration
- +Familiar to most knowledge workers
- +Huge template library for many diagram types
Limitations
- -Does not export valid BPMN 2.0 XML
- -No process validation or semantic understanding
- -BPMN shapes are cosmetic, not structural
- -No process landscapes or hierarchy
Our take: Fine for informal process sketches that stay in Confluence. If you need valid BPMN, validation, or any integration with process engines, you need a dedicated BPMN tool.
Lucidchart
General DiagrammingBPMN Compliance
BPMN shapes only, no BPMN XML export
Collaboration
Real-time multi-user editing
Pricing
Free tier (3 editable docs), from $7.95/month
Best For
Cross-functional teams that need many diagram types with great collaboration
Strengths
- +Excellent real-time collaboration

- +Google Workspace and Microsoft Teams integration
- +Supports dozens of diagram types
Limitations
- -No valid BPMN 2.0 export
- -BPMN template is cosmetic only
- -Cannot validate process correctness
- -Expensive for teams
Our take: Great collaboration tool, poor BPMN tool. The BPMN template looks professional but does not produce standards-compliant output. Use it for informal visuals, not process modeling.
Microsoft Visio
General DiagrammingBPMN Compliance
BPMN stencil, proprietary .vsdx format
Collaboration
Via SharePoint/OneDrive
Pricing
From $5/user/month (Microsoft 365 add-on)
Best For
Organizations already in the Microsoft ecosystem
Strengths
- +Deep Microsoft 365 integration
- +Familiar to enterprise users
- +Stencil libraries for many diagram types
- +Available as web app and desktop
Limitations
- -Does not export valid BPMN 2.0 XML
- -.vsdx is a proprietary format, not portable
- -No process validation or semantic awareness
- -Requires Microsoft 365 subscription
Our take: A Microsoft ecosystem tool that happens to have BPMN shapes. If you are already paying for M365 and need quick diagrams that stay in SharePoint, it works. For real BPMN, look elsewhere.
Crismo
Process Modeling + CollaborationBPMN Compliance
Full BPMN 2.0 with XML export/import
Collaboration
Real-time multiplayer editing, comments, version history
Pricing
Free tier (unlimited diagrams), Teams plan available
Best For
Teams that want collaborative BPMN modeling with process landscapes

- +Import from Visio, Signavio, draw.io
- +Free tier with no time limit
Limitations
- -Newer platform, still building governance features
- -No process mining (on the roadmap)
- -Smaller community than established players
Our take: Disclosure: we build Crismo. It is designed for teams that want to model, collaborate, and manage processes without enterprise complexity. The free tier is genuinely unlimited.
Trisotech
Standards + AutomationBPMN Compliance
Full BPMN 2.0 + DMN + CMMN
Collaboration
Multi-user with process repository
Pricing
Enterprise pricing
Best For
Organizations that need BPMN + DMN + CMMN in one platform
Strengths

- +Strong decision modeling capabilities
- +Cloud-native architecture
- +Active in standards bodies (OMG)
Limitations
- -Less known outside the standards community
- -Enterprise pricing limits accessibility
- -Smaller ecosystem than Camunda or Signavio
Our take: The standards purist choice. If you need BPMN and DMN together with strong compliance, Trisotech is excellent. For pure process modeling, simpler tools may be more approachable.
How to Choose
“I want to automate processes.”
Start with Camunda. It has the strongest execution engine and an open-source community edition.
“I need enterprise governance and compliance.”
SAP Signavio or ARIS. Both have approval workflows, audit trails, and large-org features.
“I want a free desktop modeler.”
Bizagi Modeler. Full BPMN 2.0, no limits, no cost. Windows and Mac.
“I want to collaborate with my team in real time.”
Crismo or Lucidchart. Both have Google Docs-style collaboration. Crismo produces valid BPMN, Lucidchart does not.
“I just need a quick sketch in the browser.”
bpmn.io. No signup, produces valid BPMN XML. For informal sketches, draw.io is also fine.
“I need BPMN + DMN + CMMN together.”
Trisotech. Best multi-standard support on the market.
“My team already uses Confluence.”
draw.io has the best Confluence integration. Be aware it does not produce valid BPMN.
“I am learning BPMN and want to practice.”
Start with our free tutorials, then use bpmn.io or Crismo to build your first diagrams.
"The best tool is the one your team will actually use. A perfect BPMN model in a tool nobody opens is worth less than an informal sketch on a whiteboard that everyone references daily. Start with what feels natural, then upgrade when the limitations become real."
FAQ
Which BPMN tool is completely free?
bpmn.io (open source, browser-based), Bizagi Modeler (desktop), and Crismo (free tier with unlimited diagrams) are all genuinely free. draw.io is also free but does not produce valid BPMN 2.0.
What does "valid BPMN 2.0" mean?
It means the tool exports XML that follows the Object Management Group BPMN 2.0 specification. This XML can be imported by any other BPMN-compliant tool and read by process engines like Camunda or Flowable.
Can I switch tools later?
If your current tool exports valid BPMN 2.0 XML, yes. You can move .bpmn files between any compliant tools. If your tool uses a proprietary format (like draw.io or Visio), you will need a converter.
Is Crismo biased in this comparison?
We build Crismo, so yes, we have a perspective. We have tried to be honest about every tool, including ours. Crismo is listed alongside 9 other options with the same strengths/limitations format.
Which tool should beginners start with?
bpmn.io for zero-friction start (no signup), or Crismo for a more guided experience with process landscapes. Both are free and produce valid BPMN.
