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.

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.

The idea is great, but too buggy for main driver. The shortcuts trigger randomly while typing in a text box, random text replacements that wipeout what I typed, doesn't support continuity tabs, extensions aren't there and can't use safari extensions!!

Some shortcuts conflict with my system, and refresh page too offen when switch tabs. Others ideas are much better than other browser

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.

Still, there is a big room for improvement, but I really like the opportunity to ask questions and request features in the Slack workspace where developers and the community are very welcome. While powerful shortcuts seem to be helpful, it is hard to get used to them.

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.

Pros: - You are hard to track, unless of course you make mistakes yourself (logging into your old accounts on sites, etc.). - You don't have to worry about blocked sites. - You can access sites that are not accessible through a regular network. Minuses: - Low speed.

It's a great browser. Smart, user-friendly interface and anonymous access - everything you need for privacy. I liked the simple and clear interface, the ability to change ip addresses

Very good experience..... thanks for making this
