With local sharing, you can preview your Sketch document on any device—be it a phone, a tablet, a Windows PC, a smart fridge, or anything else with a web browser. Browsers waiting for access to Mirror now appear in the popover, where you can securely control access.
Once you click on Mirror, a popover will appear providing you with a list of available devices you can connect to, along with an address you can use to share your documents for preview. Once you’ve shared the address, any browser viewing the link will be visible in the popover.
You can enable and disable access by clicking on the specific browser. When access is enabled the previewer will see a green status indicator in the top left corner of their preview browser window. When you disable the access, the indicator will turn red. While enabled, any changes you make to the Sketch document will be reflected real-time in all browsers.
