Everything you keep
checking, in view.
UltraSidebar docks a panel of live widgets to the side of your screen — and lets any one of them break out into its own floating window.
A sidebar that reserves its own space
UltraSidebar isn't a floating overlay that gets buried behind your windows. It registers with Windows as an application desktop bar, so maximized windows stop at its edge instead of hiding underneath it. Set it once and the panel is simply always there.
Docks to either edge
Pick a monitor, pick a side, set the width. Turn on Reserve Space and your other windows respect it. Or let it auto-hide and slide out when you push the cursor to the edge.
Only the widgets you want
Every widget can be switched off, reordered by dragging, resized or collapsed. Make the panel a stock ticker, a notepad, a scoreboard — or all of it at once.
Opens in your browser
Click a headline, a game, a forecast or a saved link and it opens in your normal browser with your logins and extensions — no cramped built-in viewer.
No account, no telemetry
Nothing to sign up for and nothing to pay. Your notes, tasks and settings live in a file on your PC. Widgets fetch only the data they display.
Break a widget out and put it anywhere
Click ⧉ on any widget and it opens as its own frameless window. Drag it to a second monitor, size it how you like, and leave it there — UltraSidebar reopens it in the same spot next time you sign in.
- Sits behind your other windows like a desktop gadget, so a spreadsheet or browser always covers it
- Or pin it on top with 📌 when you need it visible over everything
- Its own colors, font, text size and opacity — independent of the panel
- Notes and tasks stay in sync with the panel copy as you type

Live data, formatted for a glance
Stocks pull real quotes and intraday charts, including pre-market and after-hours prices, with true index values for the Dow and Nasdaq. Weather gives you current conditions and a multi-day forecast for as many cities as you care to track.
- Card view with charts, or a compact ticker list
- Drag cards to reorder; enlarge the ones you watch most
- Search any symbol or company by name; search cities or ZIP codes
- Separate “plus” widgets hold a second, independent set of tickers and cities
On a real desktop
Docked beside your work, popped out across a second monitor, and the settings panel where all of it gets configured.
Theme
Panel
Nineteen widgets in the box
Every one can be enabled, disabled, reordered, resized, collapsed or popped out on its own — and each keeps its own settings. Click any widget below for the full detail.
Set the look once, or per window
Appearance is a panel-wide setting that every popped-out window can override — so your notes can be dark while your calendar stays light.
Nine themes
Light, dark and in between. Every widget follows the theme automatically, including any you write yourself.
Fonts & text size
Five typefaces and four text sizes, panel-wide or per floating window — handy for a big-print list on a monitor across the room.
Paper, opacity, backup
Twelve scratchpad papers, an opacity dial so floating widgets blend into the wallpaper, and a one-file export of your whole setup.
If you can write a little JavaScript, you can add a widget
Widgets are plain .js files in a folder. Drop one in, hit Reload in settings, and it appears in the list beside the built-in ones — same titlebar, same themes, same pop-out button, no build step and nothing to compile.

About a minute, start to finish
Download the installer
You'll get UltraSidebar Setup 22.0.0.exe — a standard Windows installer, 64-bit.
Get past the Windows warnings
UltraSidebar isn't code-signed yet, so Windows shows a blue “Windows protected your PC” box, and Microsoft Defender may quarantine the file as Trojan:Win32/Wacatac.B!ml.
Both are false alarms on unsigned software — see “Why Windows warns you” below, including the checksum and the independent scan, so you can verify that for yourself rather than take my word for it. For SmartScreen: click More info, then Run anyway.
Pick your side and go
UltraSidebar opens docked to the right edge. Click the gear to choose a monitor, switch edges, set the width, turn on Reserve Space or auto-hide, and toggle the widgets you want. Press Win + Shift + S any time to show or hide the panel.
Back it up when it's just right
Settings → Backup & Restore exports your whole setup to a single file you can keep or carry to another PC.
Why Windows warns you — and how to check
UltraSidebar is an independent app from a small publisher, and the installer isn't code-signed yet. Windows treats unsigned software it hasn't seen before with suspicion, which produces two warnings: the SmartScreen “Windows protected your PC” box, and sometimes a Microsoft Defender alert naming Trojan:Win32/Wacatac.B!ml.
That Defender detection ends in !ml, meaning it came from a machine-learning guess rather than a match against any known malware. It's a well-known false positive that hits indie games, developer tools and other unsigned installers. UltraSidebar sets it off because of things it legitimately needs to do: it asks Windows to reserve screen space for the panel and to control window layering, and it can add itself to your startup items. Useful behaviour, but it resembles the shape of something unwanted to a classifier.
Don't take that on faith. The installer has been scanned by more than 70 antivirus engines and comes back completely clean:

To confirm the file you downloaded is exactly the one published here, open PowerShell in your Downloads folder and run:
Get-FileHash ".\UltraSidebar Setup 22.0.0.exe" -Algorithm SHA256
If the value matches the one above, nothing was altered between this page and your PC. Code signing is on the roadmap, which will retire both warnings for good.
