Collaborate with everyone

Experimentation works best when tapping into everyone's creativity. Shared workspaces give teams the same tools to craft hypotheses, variations and more, while highly-visual (and shareable) calendars help track all in-flight and upcoming activity. Need more experiment ideas? Crowdsource ideas with customizable intake forms — and then turn those ideas into winning variations.

  • Idea submission forms & backlog
  • Workflows, variation design tools, approval checklists
  • Shareable calendars & results repository

Design with ease

An elegant visual editor helps you target any element on your page and preview changes, while embedded AI capabilities suggest copy variations based on call-to-action messaging. From technical experts to more general users, Optimizely Web Experimentation meets you wherever you are.
