What Segmently is

Segmently is a web experimentation and personalization platform for targeting visitors by device, geography, behavior, and user attributes. Teams can run A/B, multivariate, and split URL tests using a visual editor, and can use feature flags and gradual rollouts to manage feature availability. Server-side testing is also supported. Analytics include statistical significance and confidence intervals; revenue tracking and CSV export are available on higher tiers. Segmently says its edge-native CDN delivers experiments in under 20 milliseconds worldwide. It states that the service is GDPR compliant and does not use cookies or cross-site tracking. Its JavaScript snippet works on web platforms that can load a script tag; native iOS and Android SDK support is planned, but no mobile SDK is currently listed. The Free plan costs nothing and permits one site, 500 lifetime visitors, experiment previews only, and one team member. Paid plans start at $49 a month. The product is offered on a freemium basis, with API and web listed as platforms.

Who it suits

Segmently may suit teams that want to run web experiments and personalize experiences using visitor attributes. Its free plan allows experiment building and previewing, while launching to real visitors requires a paid plan or a credit-purchased experiment slot.
