The short version

  • Both are free.
  • Where Keil MDK falls short: pricing for Essential and Professional subscriptions not disclosed on primary site.
  • Where Womp falls short: nothing is dimensionally accurate, so a form designed here has to be remodelled in CAD before it can be manufactured.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

Womp

  • Everything runs through the browser graphics stack, so an older laptop with integrated graphics hits frame rate and render limits fast and there is no local rendering fallback
  • Implicit modelling gives no control over the exported mesh, so the output topology is unsuitable for rigging, animation or subdivision work downstream
  • Nothing is dimensionally accurate, so a form designed here has to be remodelled in CAD before it can be manufactured
  • Scenes live in the vendor account, so if the service changes or closes, the only copies you hold are whatever you exported in advance
  • The material and lighting set is deliberately simplified, which caps art direction and makes the output visually recognisable as having come from Womp

Answered from the vendors’ own pages

Keil MDK: Does Keil MDK have a free version?

Yes, Keil MDK Community Edition is free for non-commercial projects. Essential and Professional editions are available as monthly or annual subscriptions.

Source
Womp: Do I need to know 3D to use it?

No. That is the point of the modelling approach; there is no topology, edge flow or subdivision to understand.

Keil MDK: How much do Keil MDK paid editions cost?

Specific pricing for Essential and Professional editions is not published on the main site. Rates are available from the Arm Developer Tools store or by contacting Arm sales.

Source
Womp: Can I use the meshes in Blender or a game engine?

You can export them, but the topology comes from tessellating an implicit surface, so it is not suitable for rigging, animation or subdivision without a retopology pass.

Womp: Is it accurate enough for manufacturing?

No. It is a visual tool. Anything to be made needs remodelling in CAD.
