The New Tab
that actually works for you.
Speedtab replaces Chrome's blank New Tab with a dense, modular workspace — bookmarks, speed dial, feeds, notes, tasks and encrypted secrets. 100% local-first, no account, optional remote sync.
World time,
inside a note.
Speedtab Clockworx is the first portable HTML-note widget: build a synchronized wall of world clocks, carry it inside your workspace, and style it as deeply as the rest of Speedtab.
Portable note widgets
Clockworx opens a configurable world-clock workspace from an HTML note — portable, interactive and entirely self-contained.
Every timezone, your way
Choose grouped IANA timezones, digital or analog faces, comparison zones and flexible date formats.
Virtual notes
Launch self-contained notes from HTML, nested YaiTabs or URL-backed content, then save the useful ones to Capture Inbox.
A real window system
Hide chrome, remove padding, pin notes in place, scope them to a page or bring any open note forward from the footer rail.
Presentation CSS
HTML notes and fetched YaiTabs can use controlled inline styles and trusted stylesheets from the official Speedtab Pages host.
Feeds feel native
Per-source favicons resolve automatically, while the new Speedfeed source demonstrates interactive first-party RSS content.
A ground-up rewrite.
10% lighter. Infinitely deeper.
Speedtab 1.4.0 was a complete architectural reboot — the same dense workspace, radically faster core, and a whole new tier of features on top.
Ground-up rewrite
Faster startup, minimal memory, zero external dependencies, brand-new architectural foundation.
10% lighter
More features, less weight. Radically optimized end-to-end — smaller install, snappier boot.
Infinite tab nesting
HTML notes now support interactive nested tab structures — tabs inside tabs, as deep as you want.
WCAG 2.1 AA accessibility
Fully keyboard-navigable (Arrow / Home / End / Enter / Space), screen-reader friendly, 100/100 Lighthouse.
Persistent window lifecycle
Floating notes remember position & size in IndexedDB — survive reloads and browser restarts.
Interactive weather popup
Click the temperature in the weather rail to open a detailed weekly forecast modal.
Smooth swipe gestures
Touch-friendly gesture navigation across your dashboard on any touch-enabled device.
Dedicated sorter surface
New sorter.html lets you rearrange your whole workspace without disturbing the live dashboard.
Isolated import / export
New import-export.html handles workspace transfers safely, away from your live nav state.
Polished onboarding
15 tailored help notes ship inside the Quick Start example workspace.
