What it does

Prototype creates several working variants of the same UI problem so a team can compare meaningful structural and interaction choices before committing to one.

Use it when

  • A design direction is still open and needs tangible options.
  • Stakeholders need to compare working variants instead of discussing abstractions.

Probably not for: Producing cosmetic variations after the main direction is already decided.

Security

Third-party security analysis is available externally. Saucekit links to the source and does not reproduce or perform the audit.
