SupaSidebar Boosts Privacy and Productivity

Most technically oriented people who value privacy do so because privacy is, and should be, a human right, not because they have something to hide.

Maintaining privacy in the current technical environment requires a real strategy and almost constant attention to an evolving landscape.

It is no longer enough to block trackers, ads, and cookies. Browser fingerprinting has become one of the primary privacy-violating mechanisms used by companies that want to identify, profile, and monetize you across the web.

One strategy many people use is spreading their work across multiple browsers. That has a second benefit: it lets you match the strengths of a particular browser to the task at hand.

Privacy and Productivity

The downside becomes obvious pretty quickly: you take a real productivity hit when your history, bookmarks, and open tabs are scattered across multiple places.

There are several tools that try to help with this. The one I like best is SupaSidebar, by developer Kshetez Vinayak. He stands out for being responsive, helpful, and clearly invested in fixing bugs and expanding the app’s usefulness. I bought SupaSidebar during the 2025 Black Friday sale and have been using it ever since.

SupaSidebar operates at the OS level. It is not a browser extension. It is built for exactly this use case: people who use multiple browsers and need a way to consolidate browser context without paying a constant productivity tax every time they switch.

Arc was a favorite of many Mac power users, and for good reason. Although it is still maintained for security, active feature development effectively stopped in early 2025. Arc introduced a genuinely useful way to manage browsing around spaces, context, and workflows. SupaSidebar recreates much of that experience, but does it across multiple browsers instead of inside just one.

The power of SupaSidebar becomes obvious when you take the time to create spaces that match how you actually work. You might have a space for research, one for personal browsing, one for work, and separate spaces for projects that need to stay isolated.

Within a space, SupaSidebar aggregates tabs and bookmarks from every supported browser you have open. It pulls in Safari, Chrome, Firefox, Arc, and others. You get a vertical, organized, searchable interface showing your open tabs across browsers.

If your browser use is simple, the free version may be enough. It supports three spaces. Paid users get unlimited spaces.

SupaSidebar also has a command panel with fuzzy search across tabs, bookmarks, history, folders, and spaces. It works like a specialized version of Spotlight for your internet life.

Features

Some of the most useful features include:

• Recents tab: shows recently visited tabs across browsers, which is useful for recovering something without keeping every tab open and burning RAM
• Multiple ways to save links: right-click, drag-and-drop, command panel, auto-routing rules, and more
• Notes for saved links: add context to a link without leaving the app
• Browser profile linking: connect a space to a specific browser profile so links open in the right place automatically
• Auto-routing rules: send links to specific spaces or browser profiles based on conditions
• AI chat mode: integrates with OpenAI, Anthropic, and Gemini directly in the panel, with Markdown rendering and slash commands

Yes, But...

SupaSidebar is still, at its core, a beta app. But it has a clear purpose, it is actively developed, and it solves a real problem that many multi-browser power users have simply learned to tolerate.

The spaces model gives it more depth than simple tab aggregation. The pricing is also reasonable, and the free tier is actually useful.

Free: 0-3 spaces
Pro: $13.99/year with unlimited spaces, early access, and priority support
Lifetime: $34.99 one-time purchase, 5 devices, lifetime updates

There are bugs and rough edges. I have seen tab synchronization inconsistencies, occasional lag when opening folders, and occasional page reloads when clicking tabs. The command panel also has some edge-case quirks around keyboard navigation.

But even with those issues, SupaSidebar is one of the more useful workflow apps I have added to my Mac setup recently.

If you stick with one browser for everything, you probably will not get much out of it. But if you live across Safari, Firefox, Chrome, Arc, and browser profiles, SupaSidebar fills a gap that Apple, Google, and Mozilla have not bothered to solve.
