Vertical tabs have been a mainstay in browsers like Microsoft Edge (and Firefox via extensions) for years, but Chrome's implementation has always felt like a work in progress. Now, Google appears ready to take a significant leap forward. Recent code commits spotted by Leo Varela on X hint at a "projects" feature that could change how Chrome users manage their browsing sessions, moving beyond simple vertical lists toward a more sophisticated panel-based organization system. For anyone juggling dozens of tabs across work, research, and personal projects, this isn't just another incremental tweak—it's a potential game-changer that signals Chrome is finally getting serious about competing with the tab management innovations we've seen in Arc, Vivaldi, and even Microsoft's own Edge browser.
What exactly is Chrome planning with "projects"?
The core concept revolves around organizing tabs into discrete, named groups that function more like workspaces than traditional tab collections. According to Leo Varela's findings, the feature appears under the internal codename "projects," suggesting a system where users can bundle related tabs together in dedicated panels. This approach mirrors workspace features already popular in competitors like Edge's Collections or Arc's Spaces, but with Chrome's massive user base, the impact could be far more significant.
What makes this particularly interesting is the timing. Chrome's vertical tabs feature has been available in experimental form since late 2024, but adoption has been tepid compared to Edge's polished implementation. The addition of project-based organization suggests Google recognizes that simply rotating tabs 90 degrees isn't enough. Users need better ways to mentally segment their browsing contexts, and it looks like Google is finally listening.
Early code references indicate panels could be collapsible, searchable, and potentially synced across devices. For power users who regularly maintain 50+ tabs across multiple contexts—say, a work project, a research deep-dive, and personal shopping—this kind of structure could dramatically reduce cognitive load and tab bar clutter. Imagine having one panel for everything related to a specific client, another for that vacation you're planning, and a third for that recipe rabbit hole you went down last Tuesday.
The specifics of how projects will integrate with Chrome's existing tab groups feature remain unclear, and there's a real risk of user confusion if Google doesn't clearly communicate the relationship between these organization methods. Still, the panel-based approach represents a conceptual shift from Chrome's historically minimalist philosophy toward acknowledging that modern web usage demands more sophisticated organizational tools.
How does this stack up against existing tab management solutions?
Chrome's move into project-based organization puts it in direct competition with browsers that have already refined these concepts. Microsoft Edge offers Collections, which let users save groups of tabs with notes and export them to Word or Excel—a productivity-focused approach that appeals to enterprise users. Arc Browser takes this further with Spaces, offering entirely separate browsing contexts with distinct visual themes and pinned tabs that feel more like desktop workspaces than browser features.
Firefox has long supported vertical tabs through extensions like Tree Style Tab, which adds hierarchical tab organization that power users swear by. Vivaldi goes even further, offering tab stacking, tiling, and workspaces out of the box, making it a favorite among tab hoarders who refuse to close anything. (We all know someone like this.) What Chrome has lacked isn't just vertical orientation—it's the conceptual framework for why you'd want tabs organized differently in the first place.
The "projects" feature appears to bridge this gap by acknowledging that modern web usage isn't linear. We don't browse one thing at a time. We maintain parallel contexts that need to be quickly accessible but not constantly visible.
The challenge Google faces isn't just technical implementation—it's execution polish. Chrome's interface has remained relatively unchanged for years, and introducing workspace-style features without disrupting the simplicity that made Chrome successful requires thoughtful design. Arc spent years refining Spaces through user feedback and iteration, while Edge leveraged its enterprise focus to position Collections as a productivity tool rather than just a tab organizer. Whether Google can deliver that same level of thoughtfulness, rather than shipping something that feels bolted onto an aging interface, will determine whether projects becomes a genuine workflow improvement or just another underused experimental feature.
What are the implications for extensions and cross-device workflows?
Here's where things get particularly compelling. One of Chrome's biggest strengths—and occasionally a weakness—is its extension ecosystem. Tab management extensions like OneTab, Toby, and Workona have thrived precisely because Chrome's native tools have been so limited. If the projects feature delivers robust native functionality, it could render many of these extensions obsolete, or at least force them to evolve into more specialized tools that address edge cases the native feature doesn't cover.
The cross-device angle is where projects could genuinely transform Chrome's usability. Chrome's sync infrastructure already handles bookmarks, passwords, and settings admirably, but it treats tabs as a flat list that becomes increasingly unwieldy across multiple devices. If projects can sync as discrete units, the workflow implications are substantial: you could start a research project on your desktop, continue it on your laptop during a commute, and review it on a tablet later—all without losing context or manually hunting through tab histories. Unlike the current "open tabs" sync that simply dumps everything into an undifferentiated list, project-based sync would maintain the contextual boundaries that make tab organization useful in the first place.
The enterprise consideration adds another dimension. Google Workspace users often juggle multiple accounts and projects simultaneously, and better tab organization could reduce the need for separate Chrome profiles or browser windows—a common workaround that adds friction to context switching. The feature's panel-based approach suggests Google is thinking about these multi-context workflows, though whether admin controls or team collaboration features will be part of the package remains speculative. A shared project panel capability would align with Google Workspace's collaborative focus, but there's no indication in the leaked Chromium code commits that this functionality is being developed.
Where does Chrome go from here with browser UX?
The browser wars have shifted from speed benchmarks to user experience differentiation. Chrome dominated the 2010s by being faster and simpler than Internet Explorer and Firefox, but today's competition centers on workflow optimization, privacy features, and interface innovation. Google's investment in vertical tabs and projects signals an acknowledgment that raw performance alone isn't enough when competitors are offering genuinely better ways to organize digital work.
What remains uncertain is how projects will integrate with Chrome's existing features. Will it work alongside tab groups, potentially creating confusion about which organizational method to use? Will it connect with the side panel, reading lists, or Chrome's nascent AI features? The code commits suggest this is still in active development, which means the final implementation could look quite different from what's currently visible in experimental builds.
The risk Google needs to navigate carefully is launching something that confuses users rather than empowering them. Chrome's history with experimental features is inconsistent—some, like tab groups, became genuinely useful, while others launched with unclear value propositions and quietly faded away. The projects feature needs clear documentation, intuitive UI, and a compelling answer to the question: "Why should I use this instead of just opening another window?"
Bottom line: Chrome's vertical tab evolution and the potential projects feature represent the most significant rethinking of Chrome's tab interface in years. For heavy tab users and productivity enthusiasts, this could finally make Chrome competitive with the workflow innovations that have made browsers like Arc and Edge so compelling. Whether Google can execute with the polish and thoughtfulness required remains the open question, but at least they're finally asking the right questions about how people actually use browsers in 2025. And that's a start worth watching.
