For example, we can use Chrome Inspector's "Device" previews, but we run into the following:

- Chrome doesn't keep those devices/viewports up to date, and adding new ones is pretty annoying (we've open sourced our collection of 180+ viewports/dimensions under MIT).

- You can’t see multiple viewports at once (and it’s cumbersome switching back and forth)

- When you notice a problem, there's no simple way to deep-link someone on your team to take a look at that viewport (likely have to open a Jira/Linear with the specifics)

- You can’t favourite viewports (for tracking the viewports specific to your project/client)

We’ve built a product with the goal of addressing these limitations (among others), and would love to hear your feedback.

Finally, feel free to use the open sourced data for your own projects :)
