Tree Style Tab for Chrome: Sidebery Alternatives (2026)

There is no Tree Style Tab for Chrome, and Sidebery has no Chrome version: both are Firefox-only. If you want full titles down the side, turn on the vertical tabs built into Chrome, Edge and Brave; if you need a real parent-child tree, Tabs Outliner (100,000 users) is the closest match.

Why can't you get Tree Style Tab or Sidebery in Chrome?

Both depend on Firefox APIs, and Chrome extensions cannot replace the tab strip.

• Tree Style Tab's author says it relies on Firefox-specific APIs such as sidebar, so it cannot be ported. Sidebery is a Firefox extension with no Chrome build.
• Any Chrome "tree tabs" extension shows a copy of your tabs in a panel or window; the normal tab strip stays.
• Both are healthy on Mozilla Add-ons: Tree Style Tab has about 140,000 daily users (4.4.9, September 30, 2026), Sidebery about 54,000 (5.6.1, September 16, 2026, MIT).

Tree Style Tab for Chrome: the options compared

Native vertical tabs

Best for: reading full titles down the side, with nothing to install.

• Chrome: right-click the tab strip, Show Tabs Vertically, or Settings, Appearance, Tab position (Google). Rolled out in phases during 2026.
• Edge: Search tabs icon, Turn on vertical tabs, or Ctrl + Shift + , (Microsoft). Brave: right-click a tab; since 1.52 (Brave).
• Skip it if you need nesting: groups are one level deep.

Tabs Outliner

Best for: a real tree where new tabs nest under their opener.

Tabs Outliner lets you drag and nest nodes, add notes and "close and save" a window as a branch. It exports to HTML, Google Docs or Word.

• Scenario: snap its window to the left edge of a wide monitor for a near Tree Style Tab layout.
• Weakness: separate window, not a sidebar; 3.2 rating, updated July 23, 2026.
• Price: free core; shortcuts and Drive backups need a one-time payment (price not listed).

Tab Manager Plus

Best for: Sidebery users who relied on panels and search more than the tree.

Tab Manager Plus shows every window as a list or grid, with regex filters and named, colored windows.

• Fact: highlights duplicates, caps tabs per window; 7.0.0 shipped October 15, 2026.
• Weakness: no tree and, per its README, no tab group support yet.
• Price: free, MPL-2.0.

SuperCommands

Best for: Sidebery panels that were really projects you return to.

Save each project as a link collection instead of keeping it open for weeks.

• Scenario: press Alt + S, type c link, pick CI dashboard, repo and staging from Current Tabs, add the text shortcut build. Typing c, Space, build in the address bar reopens all three (Links docs).
• Weakness: no live tree or sidebar; saves URLs, not tab state.
• Price: free and open source; the local version is 100% free, forever.

Should you just stay on Firefox?

Yes, if you follow chains of 30 links three levels deep during research. Nothing in Chrome reproduces Tree Style Tab inside the main window.

Which one should you pick?

• Pick native vertical tabs if you only wanted titles down the side.
• Pick Tabs Outliner if you need the parent-child tree.
• Pick Tab Manager Plus if you want named windows and regex search.
• Pick SuperCommands if your panels were projects. See also how to organize hundreds of browser tabs and our best tab manager extensions.
