SigmaOS markets itself as "the first browser specifically made for work" and targets "students managing courses" and "founders building startups." Yet it fundamentally fails at the most basic institutional workflow: SSO redirect authentication. Without this fundamental and game-breaking failure, it would easily be a 5 star browser and I would have no complaints. Every university library system (Ex Libris, OCLC), corporate SSO (Okta, SAML), government portal, and B2B platform uses redirect-based authentication. You save the redirect URL, click it, authenticate, and access your tools. This is Web 101 for institutional users. SigmaOS removed traditional bookmarks without understanding what bookmarks actually do - they're deferred execution triggers for authentication flows. Their "locked pages" system requires visiting a URL first, but redirect URLs auto-forward immediately, making it impossible to save the trigger URL. The "Edit locked URL" feature is broken - when you try to reset to your saved redirect, it errors out when trying to load the redirect URL instead of executing the authentication flow. Meanwhile, Arc handles this perfectly with persistent saved tabs with editable URLs, and Chrome, Safari and Firefox handle it perfectly with bookmarks. (But all of these other browsers fail for my workflow for other reasons.) How can you charge a monthly subscription for a "work browser" that can't access the tools people actually use for work? Either fix redirect URL handling, or stop marketing as a "work browser" to institutional users.

After one too many minor frustrations with Safari, and a mention from a friend about this new project called SigmaOS, I decided to give this browser a try. A few months later, it is my default browser. I wouldn’t recommend SigmaOS for everyone, but for people who spend a lot of time in a browser and who are looking for a streamlined and focused workflow, this browser has a lot to offer. Instead of tabs becoming a clutter of nonsense like was my experience in the past, SigmaOS encourages me to view tabs as a todo list—items I can check off as I complete the associated tasks. Plus it looks really clean and simple, so it’s a pleasure to use. I have yet to see any value in generative AI in a browser, but they’re doing that too so we’ll see where it goes.

This is the browser I've been searching for, it takes the current browser UI/UX paradigms and turns them on their head to use a more contextual computing model and an emphasis on tasks over sites. Add in the command palette and extensive keyboard shortcuts and it's really increasing my productivity in just a short time using it. It's certainly still early and rough around the edges, I'm very much looking forward to custom search engines, extensions, more minimalist and custom to workspace icons and it will be the only browser I have open. I'm seriously excited about its future! I also love how responsive the team is, that's a huge benefit!

It's abandonware at this point. They're more than happy to take your subscription money, but they don't show up for scheduled onboarding calls anymore, the guidance provided by the founder over email to address usability issues isn't accurate, and the core experience is lacking. Extensions rarely work, it's laggy, and effective customer service is nonexistent. This is unacceptable for a product that asks for a monthly subscription.

I am impressed by the onboarding to the features and the good layout for easy navigation, especially the left side panel with "workspaces" and "tabs". However, I hope that I can continue to use the plug-ins familiar to my work (Save to Notion, Wappalyzer,..). They are not working for now in sigmaOS. Thank you for a great browser anyway.

SigmaOS has become a daily part of my life and work, and it’s made both significantly better. When you use it, everything just makes sense - huge kudos to their product team for designing something that is so intuitive and matches any human’s average mental model when it comes to browsing experience. And extra points for their responsiveness to reported bugs (few and iterated on incredibly quick) and to answering questions in the very active Slack community.

Exceptional. Categorizing it as a Browser is like calling an iPad as a tablet. It is not a Browser, it is Sigma. At first, it took me a couple of days to get used to it and in the meantime, there have been times that I just went back to Chrome. But after getting used to it and especially customizing it, it saves you time and makes you organized. It is something really different and the help/support is mindblowing.

It's one of the best browsers I have used. My only real negatives are that it's not one of the faster browsers (they're working on it and make bi-weekly updates) and the second negative is: it's not currently going to any other platform other than Mac. This NEEDS to come to Windows for me to taking it the most serious. I pray that it does, because it really is a great browser.

Its a browser you never knew you needed. I was on a hunt for a browser where I can manage my tabs better than I could do on Chrome. But since most browsers are chromium based, they have the same functionality. Safari came closest to the way I wanted my tabs to be managed but it brought its own set of problems. SigmaOS is exactly what I was hoping in my browser, and more!

I’ve been on the hunt for a better browser and SigmOS has blown me away. Within a few days it feels so intuitive I can’t imagine going back. The split screen, workspaces and shortcuts amke using it a pleasure. The UX has been so well thought through for the way we use browsers now. Well done team!!
