Sherlo review
A Storybook-centered way to capture, compare, and review React Native screens in the cloud.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sherlo is a cloud visual regression testing service for React Native applications, aimed at teams reviewing simulator screenshots across iOS and Android. It captures Storybook stories on both platforms and compares them with previous versions to surface visual changes. The vendor says it supports Expo and bare React Native projects, but Storybook is currently required, so teams without that workflow will need another approach.
The review workflow combines approve or reject actions, comments, before-and-after views with highlighted changes, and browser-based inspection of React Native styles. Teams can also compare screens side by side with Figma designs and test variations in device, OS version, theme, locale, and font scale. Storybook, Figma, and Slack are the listed integrations. This makes Sherlo most relevant to teams that want cloud simulator coverage and collaborative review around React Native components; it is a narrower fit for projects seeking cross-browser testing or a local runner.
The Free plan costs $0 per month and includes Android and iOS, Visual Testing Cloud, Review App, Code Inspector, Figma integration, and Slack integration. Starter is $179 per month and adds a high-priority queue; Pro is $399 per month and adds a top-priority queue. Both paid tiers charge $0.008 per extra snapshot. Enterprise lists dedicated support and a critical-priority queue. Published support channels are email and docs. Choose Sherlo if simulator-based React Native review and configuration variants are central to your workflow; look elsewhere if Storybook is not part of your setup or you need local execution.
