The short version

  • Only Linearity Curve has a free tier, so it costs nothing to try first.
  • 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.; Linearity Curve limited to Apple ecosystem (Mac, iPad, iPhone) with no Windows or Linux support
  • They diverge on capability: Axure RP covers Conditional logic, Linearity Curve covers Vector editing.
  • 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.

Linearity Curve

  • Limited to Apple ecosystem (Mac, iPad, iPhone) with no Windows or Linux support
  • Requires annual or monthly subscription for commercial use, unlike competitors offering lifetime purchase options
  • Free plan is severely limited to only 3 Curve files and 5GB storage

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.

Linearity Curve: What file formats can I export from Linearity Curve?

Linearity Curve supports exporting to industry-standard formats including .ai, SVG, PDF, PNG, JPG, and TIFF, making it compatible with other design tools.
