YabYab 0.0.24
Tabs open faster than in Chrome, Back and Forward at once, 200 tabs in half Chrome's memory, and userscripts and snippets kept in Yab.
Added
Userscripts
A .user.js offers to keep it in Yab, beside boosts, and scripts move over from Tampermonkey.
Snippets
Type ;name in any box on a page to paste a snippet, ⌘; lists them, and Yab offers to keep what you paste often.
Buttons on sites
Agent buttons on GitHub, Linear, Google Calendar, Amazon and X, and Do It with Claude in Slack and Gmail.
Password managers
A connected manager fills through its own menu, with no second sign-in and no second save prompt. Touch ID unlocks a manager once a session.
JSON viewer
A link that answers with JSON opens as a tree.
Zoom and Slack calls
Zoom calls and Slack huddles get the call window, as Meet calls do.
Extension search engines
An extension's own search engine, such as ChatGPT search's, can be picked in Settings › Search.
DevTools search
Elements finds nodes as Chrome does, also inside frames. Sources searches every file, with match case, regular expressions and the lines grouped by file.
Invite a Friend
An Invite a Friend button beside the About menu in ⌘T, and at the top of the About menu.
Shortcuts sync
Keyboard shortcuts changed on another Mac take effect at once.
Improved
Opening tabs
A tab opened in front shows its page about twice as fast, around 50 ms instead of 100, now quicker than Chrome: the page draws first, the sidebar a moment after.
Back and Forward
Back and Forward show the page as you left it at once, in about 20 ms instead of 60 to 100, and the menu bar and window title follow a moment later.
Sleeping tabs
A tab that was asleep wakes about twice as fast, with or without extensions.
Many tabs
With many tabs open, tabs of the same site share their memory, as in Chrome: 200 tabs take about 3.7 GB instead of 5.1, where Chrome takes about 7.6.
Hidden tabs
Hidden tabs' timers slow down the longer they stay hidden, as in Safari, and their memory is tidied while you are away. With 200 tabs open, Yab at rest uses under half a percent of a core instead of 17%. Chats, mail and calls in hidden tabs keep working.
Extensions
Heavy extension scripts (1Password, NordPass, MetaMask, Grammarly) wait for the page's first frame, so pages show sooner: with MetaMask a new tab shows in about 70 ms instead of 160, with ten extensions in 170 ms instead of 280, faster than Chrome with the same extensions.
Scrolling
Scrolling a page takes less than half the work it did, and the sidebar with many tabs about a quarter less, so frames keep up on busy pages. A mouse wheel keeps scrolling what it started on.
Launch
Yab starts sooner: the first page loads as soon as its window is up.
Tabs across the top
A tab shows its icon, title and close button, as in Chrome, with every icon on whole points.
Tearing off a tab
A tab pulled out of the window grows out of its row into the card, as in Arc.
Empty window
An empty window shows what is behind it, blurred under the space's color, as in Arc.
Moving the window
The sidebar's top band drags the window everywhere but its buttons, as in Arc.
Settings
Settings › Tabs keeps four rows, as in Arc. What Yab sends now sits under Privacy, and what ⌘J opens under AI.
Updates
Yab waits at least a day between updates.

New experiments
Actions in the Field
Words in ⌘T that read as something to do get a row on top that shows what Yab already knows, then does it, opens the site's own form filled in, or hands it to the agent. Read by this Mac's own model, or by Jev on your own OpenRouter key, added in Settings › AI › Models. Turn it on in Settings › Experimental.

Fixed
Crashes
Fixed crashes in the Network table, in downloads, and in the share picker.
Picture in Picture
A site's own Picture in Picture button and ⇧⌘P put the video in Yab's window again, with its controls; the page stays in its tab, and the window stays up when Yab is hidden.
Sign-in codes
Boxes for a sign-in code no longer offer to fill a form, and the offer no longer hangs over the next page.
Folders
Dropping a tab near another row's edge inserts it there; only its middle makes a folder.
Split View
⌘S beside a Split View always moves the sidebar and both halves together.
Videos
A video opened as a page plays instead of failing to load.
Dark mode
An empty window no longer flashes white in dark mode.
Chats
Picking a chat from the sidebar's list no longer shows the chat before it.
New chat
⌘N in a chat's field starts a new chat instead of a new window.
Hidden sidebar
A tab's card in the hidden sidebar hangs beside its row, not off the window's edge.
Dates
Relative dates read in English on a Mac set to another language.
AdBlock
AdBlock 6.49 updates again: a rule WebKit can't take no longer fails the whole update.
Mail
Now reads dates in mail better and tells automatic alerts from people.
Free, for macOS 15.4 or later.
