The whole portal
Index pages, records, boards, tickets, workflows, and settings — not just the chrome around one view.
Chrome extension
HubSpot, after dark.
A real dark mode for the portal you live in. Contacts, deals, tickets, workflows, settings. Preview it here, then load it in Chrome in about thirty seconds.
Live portal
Same stylesheet the extension injects. Toggle it. Open a contact. Switch to deals.

Four themes
Midnight for long sessions, Slate for HubSpot-native navy, OLED for true black, Dusk for warm evenings.
Orange stays orange
Primary buttons keep HubSpot’s coral. Charts and images are not inverted. Precision is the default engine.
Nothing leaves the browser
No account. No analytics. Host permissions cover *.hubspot.com and *.hubspot.net only.
EU, NA, AP
Regional apps (app-eu1, app-na2, and the rest) match the same host pattern. Settings sync with Chrome.
Load unpacked
Not on the Chrome Web Store yet. You unzip it, flip Developer mode, and point Chrome at the folder.
Load it in Chrome
Chrome will warn that the extension is unpacked. That’s expected. Umbra only injects CSS into HubSpot. Already installed? Open chrome://extensions and hit Reload on Umbra after downloading a new zip.
- Step 1
Download the zip and unzip it. You should see manifest.json.
- Step 2
Open chrome://extensions and turn on Developer mode.
- Step 3
Click Load unpacked and select the unzipped folder.
- Step 4
Open your HubSpot portal. Use the toolbar icon to change theme.
