Are you sick of working in a slow and tab-cluttered browser?

Today, anyone who works in a browser fights to stay organized. Tabs are out of control, browser windows are all over the place, and desktop apps may work on their own, but they don’t integrate well with the rest of your work on the web.

Sidekick changes all of that.

What makes Sidekick stand out?

Lightning fast

Block trackers

Sidekick doesn’t have an ad-based business model, so we can block ads and trackers without compromise.

AI based tab suspension

Sidekick saves memory by automatically suspending tabs that you don’t need at the moment.

Improved tab memory management

Sidekick uses significantly less memory when you work with similar tabs.

Work in apps instead of tabs

You spend 90% of your time working in web applications. So we reimagined the browser UX around apps—a better way to work in the most productive applications on the web.

Get your tabs organized with sessions

While working, tabs somehow always multiply out of control. So we created a way to effortlessly manage them with sessions. Now you can make tabs work for you and say goodbye to tab clutter forever.

Keep your tabs together

As you work Sidekick groups your tabs into a session. Create multiple sessions and organize them around your workflow.

Manage tabs effortlessly

Access all your sessions from Sidekick’s sidecar. From there you can open, pin, organize, or move your tabs in just a few seconds.

Switch between sessions

All sessions are automatically saved. See only the tabs you need at a time and then switch between sessions with just a click.

We’ll never sell your data

We don't make money through ads or selling data like other browsers, so we can afford a no compromise approach to the privacy

Block data-grabbing ads

Sidekick blocks virtually every data-grabbing ad and tracker. Even the ones that other browsers say “respect your privacy”.

Respected privacy

Sidekick never sells access to your data. That includes your searches, your browsing history, and your personal information.

Boost your work productivity

Get Sidekick and get to work as soon as you get online

I think Sidekick is perfect! It’s fast and the UI is simple and incredibly customizable. Now the feature that won me over was the fact that it does not take as many resources as chrome does from my pc.

Now i have an ability to organize everything in one place (all my open tabs into browser groups). Can have 50+ open tabs without crashes. Super!

Still enjoying Sidekick. I now work within the browser as part of my full-time job, and appreciate that you built this on top of Chromium thus ensuring the security of the application, as well as adding more security on top. I love Sidekick!

I’ve been really enjoying my experience with Sidekick so far and will post some feature requests in the coming days. Sidebar is super-feature, shortcuts are really helping in everyday routine

I am absolutely loving Sidekick! Sidekick lets me keep the sites I use all the time handy without the need to worry about a bunch of open tabs!

It’s user friendly and very intuitive from my opinion. I’ve never thought a browser can have that much functionality!
