The short version

  • Each has a real cost: Axure RP a large prototype with variables and repeaters is effectively an application, but it has no version control diffing, no tests and no code review, so maintaining one for years is a genuine engineering cost carried by a designer.; Principle macOS only with no Windows or Linux editor available
  • They diverge on capability: Axure RP covers Conditional logic, Principle covers Timeline-based animation.
  • 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.

Axure RP

  • A large prototype with variables and repeaters is effectively an application, but it has no version control diffing, no tests and no code review, so maintaining one for years is a genuine engineering cost carried by a designer.
  • The Windows and macOS builds have historically differed in behaviour and file handling, which causes conversion problems in mixed teams.
  • The output is never production code, so every rule you carefully modelled is reimplemented from scratch by engineers, and the two versions then diverge.
  • Subscription replaced the perpetual licence at RP 10, so teams that bought RP 9 outright must now pay annually to receive any new major version.
  • The visual design tooling is dated next to Figma, so most teams design elsewhere and import, which leaves two sources of truth to keep aligned.

Principle

  • macOS only with no Windows or Linux editor available
  • No vector morphing capability for complex shape transformations
  • Limited asset creation tools; cannot create vectors or shapes directly within Principle
  • Sketch import flattens certain properties including paths, fills, borders, masks, blur effects, and text layers
  • Limited variable support, logical loops, and data input capabilities compared to tools like ProtoPie or Origami

Answered from the vendors’ own pages

Axure RP: Can I still buy a perpetual licence?

No. Axure moved to subscription with RP 10. Existing perpetual licences keep working but do not receive new major versions.

Principle: Does Principle run on Windows or Linux?

No. Principle is macOS only and runs on Intel and Apple Silicon Macs. There is no Windows or Linux editor available; however, prototypes can be shared and viewed on any platform via web link.

Source
Axure RP: Can prototypes be hosted on our own servers?

Yes. Prototypes export as a self-contained HTML bundle, and Axure Cloud for Business can be deployed on customer infrastructure.

Principle: What is the cost of Principle?

Principle costs $129 for a one-time purchase with 1 year of upgrades included. After 1 year, upgrade licenses cost $99/year. A 14-day free trial is available with all features included.

Source
Axure RP: Is it worth it if we already use Figma?

Only if you need conditional logic, data-bound components or generated specifications. For click-through review of static screens it adds cost without adding capability.

Principle: Can I import designs from Figma or Sketch into Principle?

Yes. Principle supports importing designs from Figma and Sketch with intelligent merging of re-imported files. Some Sketch properties such as paths, fills, borders, blur effects, masks, and text layers are flattened upon import.

Source
Principle: How do I share Principle prototypes with others?

Prototypes can be shared via web link with one click (File > Export > Share to Web). Recipients can view and interact with prototypes in any browser on any platform: Windows, macOS, Linux, Android, or iOS. No installation required.

Source
Principle: Can I create vector shapes and morphing animations in Principle?

Principle does not support vector morphing, where vector objects transform into other vector shapes. It also has limited asset creation capabilities and editing is restricted to basic operations like scale and rotate.
