1. Cloud Architecture and Setup

Feature	Onshape PDM	Sibe
Cloud-native	✅ Yes	✅ Yes
Server requirements	❌ None	❌ None
Onboarding time	Moderate (full platform switch)	Very fast (no migration required)
CAD tool dependency	Requires using Onshape CAD	Works with SolidWorks & Inventor via add-in

Summary:

Onshape offers an all-in-one cloud CAD + PDM solution, but requires switching entirely to the Onshape CAD environment. In contrast, Sibe integrates directly with SolidWorks, making it easier to adopt without changing your core CAD tools.

‍

2. Version Control and Design History

Feature	Onshape PDM	Sibe
Design history tracking	✅ Full document history & version tree	✅ Full file-level version control
Compare versions	✅ Yes	✅ Yes (via SolidWorks add-in)

Summary:

Both tools offer detailed version control, but Sibe allows for usage inside SolidWorks and provides native file-based control familiar to most engineers.

‍

3. Collaboration & Access Control

Feature	Onshape PDM	Sibe
Real-time collaboration	✅ Branch & merge model	✅ Check-out/check-in with live locking
External sharing	✅ Via Publications	✅ Browser-based viewer, unlimited free users
Role-based access	✅ Built-in	✅ Granular user roles & download restrictions

Summary:

Onshape enables real-time editing with branching workflows. Sibe uses check-in/out control with live file locking, more in line with traditional CAD workflows but with the ease of cloud-based sharing.

‍

4. Workflow & Release Management

Feature	Onshape PDM	Sibe
Custom workflows	✅ Limited customization	✅ Fully customizable
Revision management	✅ Built-in approvals	✅ Task-based with pinning & audit trails
Change order tracking	❌ Limited	✅ Assign and track design changes

Summary:

Sibe offers more granular control over engineering change orders and workflows, while Onshape favors speed and simplicity through standardized processes.

‍

5. CAD Ecosystem Compatibility

Feature	Onshape PDM	Sibe
Native SolidWorks add-in	❌ Not available	✅ Yes
Inventor support	❌ Not supported	✅ Yes
Support for other CAD files	✅ Onshape format only	✅ 30+ CAD formats via browser access

Summary:

If you’re using SolidWorks, Inventor, or working with multi-CAD files, Sibe is purpose-built to handle that environment. Onshape is ideal only if you’re fully committed to its ecosystem.

‍

6. Pricing & Scalability

Feature	Onshape PDM	Sibe
Free tier	❌ Non-commercial use only	✅ Free forever plan for small teams
Premium pricing	starts at $1500/year/seat (CAD + PDM)	starts at €500/year/seat
Cost of viewers	All files visible to public	Unlimited free viewers

Summary:

Sibe is more cost-effective for small to medium-sized teams, especially when you need flexible viewer access and don’t want to pay for every seat.

‍

Final Verdict: Sibe or Onshape PDM?

Use Case	Best Choice
You're fully switching to Onshape CAD	✅ Onshape PDM
You're using SolidWorks or Inventor	✅ Sibe
You need to collaborate with non-CAD users	✅ Sibe
You want a simple, affordable PDM setup	✅ Sibe

Conclusion

Both Onshape and Sibe offer modern, cloud-first PDM solutions—but they serve different needs.

If you’re committed to the Onshape ecosystem and want real-time CAD collaboration with built-in PDM, Onshape is the right fit.
If you’re a SolidWorks or Inventor user looking for a flexible, cost-effective cloud PDM with minimal setup, Sibe is purpose-built for you.
