A dark theme for the classic ConnectWise Manage screens. It installs as a userscript, which means a small free browser extension called Tampermonkey stores the theme and applies it to ConnectWise automatically on every visit.
The Calendar page is finished. Every other ConnectWise screen stays light until a script for it exists. Setup takes about three minutes and happens once per computer.
Open tampermonkey.net and pick the matching browser. Chrome and Edge both work. The extension is free.
Chrome version 127 and newer need one extra switch. Open
chrome://extensions, click Details under Tampermonkey, then
turn on Allow User Scripts. Skipping this switch is the most common
reason a script installs but nothing changes.
Press the Calendar button below, then press Install. Tampermonkey opens its own install screen. Press its Install button as well.
Copy is the manual route if the install screen does not appear. Open the Tampermonkey dashboard, press the + tab, select everything already in the editor, paste over it, then press Ctrl+S.
ConnectWise runs as a single page application. Moving between screens inside it never reloads scripts, so a new script appears to do nothing until the browser itself reloads. Press Ctrl+R on the ConnectWise tab.
A small SD dark badge sits near the top right of the ConnectWise window. A green dot means the theme is active on the page currently open. A grey dot means that page has no theme yet, which is normal anywhere other than Calendar.
Click the badge, then click the Dark theme switch. The page reloads and the setting sticks until it is switched back. Nothing needs uninstalling to go back to the standard look.
Nothing leaves the computer. The script only restyles pages already open in the browser, and it reads no ticket or client data.
After a ConnectWise update, small areas can come back light. Clicking the badge and then Check health lists anything the theme could not cover. The script is written to survive most updates on its own.
Removing it completely: open the Tampermonkey dashboard and delete the script from the list.
