I've been using it for two years. At first it was my favorite handy browser for work. I really liked the way the sessions worked. But then, when there were too many sessions, it became awkward to navigate through them because there is no search by session name. No way to bookmark a session so you don't get confused by the list. All browser functionality is now paid for.
Unfortunately, I had to switch to the Opera browser with unchanged session names.
Sidekick has a great browser they've put together. My journey began with Chrome Canary then Franz then Station (RIP). Eventually, I was glad to find and stick with Sidekick as my daily driver. It is the browser I switched to and have advocated for time and time again (I put a link to it in our onboarding manual for my firm). What I appreciate is how it saves me installing 5-10 different Chrome extensions because they're natively baked into the browser (tab management, RAM management, and general organisation). It also assists greatly with its keyboard shortcuts, ad blocker, and distraction blocker. I recommend it.
I am the President of a an amazing Digital Agency and I could not survive without the amazing browser. I have tried so many, and this one was super great to organize and make it easy to focus. Love it and highly recommend it. I am a PAID subscriber and will gladly keep paying for these amazing upgrades!
