The short version

  • Each has a real cost: COMSOL Multiphysics the base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.; KeyShot professional plan costs £108.25/month per user; total cost for small teams can be substantial
  • They diverge on capability: COMSOL Multiphysics covers Coupled multiphysics solving, KeyShot covers Real-time rendering.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

COMSOL Multiphysics

  • The base licence covers very little on its own and nearly every practical problem needs one or more add-on modules, each priced separately, so the quoted total is typically a multiple of the headline base figure.
  • Perpetual licences renew maintenance at 20% of the then-current price each year, and because that percentage applies to the whole module stack the annual bill grows as your module list does and as list prices rise.
  • No pricing at all is published, so procurement cannot benchmark or budget without a sales engagement, and comparisons against Ansys or SolidWorks Simulation are effectively impossible before that point.
  • Named Single-User and CPU-locked licences do not share, so a team of six that bought individual licences ends up with idle seats while a Floating Network Licence would have covered them, and switching licence type is a commercial renegotiation.
  • Solving strongly coupled systems is memory hungry and slow, and models that look modest in the GUI routinely need tens of gigabytes of RAM, so hardware cost is a real and often underestimated part of adoption.

KeyShot

  • Professional plan costs £108.25/month per user; total cost for small teams can be substantial
  • 3-year commitment reduces to £3,897 per user, but locks in pricing for extended period
  • Network Rendering, Studio VR, and Cloud Rendering are paid add-ons (£29-£99/month additional)
  • No clear platform support information; likely Windows-only based on CAD tool integrations

Questions people ask

Is COMSOL Multiphysics or KeyShot better?
Neither clearly leads. COMSOL Multiphysics starts at On request and KeyShot at $1299/year, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, COMSOL Multiphysics or KeyShot?
COMSOL Multiphysics starts at On request and KeyShot at $1299/year.
Does COMSOL Multiphysics or KeyShot run on more platforms?
COMSOL Multiphysics runs on Windows, Linux, macOS. KeyShot runs on Windows.
What is COMSOL Multiphysics best used for?
COMSOL Multiphysics is most often used for modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the field, research work needing custom partial differential equations that no packaged solver in a mainstream tool provides, packaging a validated model as an app so process engineers can run studies without learning the simulation tool, a department wanting shared concurrent access via a floating network licence, with cluster runs at no extra licence cost. Of those, modelling a device where physics are strongly coupled, such as induction heating that changes material properties which change the field and research work needing custom partial differential equations that no packaged solver in a mainstream tool provides are not what KeyShot is typically brought in for.
What can COMSOL Multiphysics do that KeyShot cannot?
COMSOL Multiphysics covers Coupled multiphysics solving, Equation-based modelling, Add-on module library, Application Builder. KeyShot covers Real-time rendering, Ray tracing, Animation, Material library.

Answered from the vendors’ own pages

COMSOL Multiphysics: Does the base licence include CFD or structural mechanics?

Only limited capability. Serious CFD, structural, RF and acoustics work each require the relevant add-on module at extra cost.

KeyShot: What is the difference between KeyShot Professional and Business licenses?

Professional ($1,299/year) is for individual designers with non-transferable seats. Business ($1,599/year) includes transferable seats, centralized management, and is designed for team use. Professional does not include network rendering options.

Source
COMSOL Multiphysics: What does maintenance cost?

Perpetual licences include 12 months of updates and support, then renew at 20% of the then-current price per year.

KeyShot: Can I pay monthly for KeyShot instead of annually?

No, KeyShot pricing is structured around annual subscriptions. Professional is $1,299/year ($108.25/month equivalent) and Business is $1,599/year ($133.25/month equivalent). 3-year terms offer lower per-year costs.

Source
COMSOL Multiphysics: Which licence type should a team buy?

Floating Network if more than a couple of people use it, since it shares concurrency and includes cluster and cloud computing at no extra charge.

KeyShot: What add-on costs should I budget for KeyShot Studio VR?

KeyShot Studio VR costs $99/month or $1,188/year separately. Network Rendering is $32/month ($384/year) and NX Plugin is $29/month ($348/year).

Source
COMSOL Multiphysics: Is pricing published?

No. COMSOL publishes licence types but no prices; every purchase goes through a quote.

KeyShot: Is educational pricing available for KeyShot?

Yes, KeyShot offers EDU tier licensing for eligible students and faculty at $95/year, providing access to identical core features and AI capabilities as paid plans.
