LambdaTest
Review & Alternatives (2026 Guide)

It's like Sizzy, but without a subscription, lag, and 10x better. I don't know what to write because it does precisely what the developers promised! It's a must-have if you're building a startup!

Thrilled about the LT Browser 2.0 launch! Game-changer for devs, testers, and designers with real-time responsiveness testing across multiple devices. It even seems like a better responsive test version of BrowserStack. Congrats team, and can't wait to explore more!

Congrats on the launch 🚀🚀🚀! Super cool.

-Network throttling feature is great -Rotate button is a good idea too -"Mark as bug" is good because in startup development you'll get errors that nobody really cares about, so it's good that you let us decide what to mark as a bug :)

Some things I think could be better (take this with a grain of salt).

-It wasn't super obvious to me how to add multiple devices. My eyes were drawn to the left panel, and I thought that was how to add devices. But the left panel was how to replace devices. I think the button on the top right should be more apparent. -On the phone (Galaxy Note 9), when I set zoom to 150% it brings the whole device closer (which is what I want). But on desktop, it just zooms in from the device's perspective and doesn't bring the whole device closer. Is that intentional?
