What do I need to run Microsoft Edge Insider (Canary/Dev)?
Currently, Microsoft Edge Insider (Canary/Dev) builds are designed for Windows 10. Beta builds will come online in the future. Support for Mac and all supported versions of Windows will also come over time.
You can even choose to install multiple channels side-by-side for testing—they will have separate icons and names so you can tell them apart.
Microsoft Edge Insider (Canary/Dev) builds won't override your current Microsoft Edge.
