Install TabSlate

From an official browser store

TabSlate is published on three official extension stores:

• Chrome Web Store: Install TabSlate for Chrome
• Microsoft Edge Add-ons: Install TabSlate for Edge
• Firefox Add-ons: Install TabSlate for Firefox (Firefox 142 or later)

Install from whichever store matches your browser, then open a new tab. TabSlate replaces your browser's default new-tab page, so the workspace opens automatically — there is nothing else to launch.

Build from source

TabSlate is open source. To build and load it yourself:

git clone https://github.com/TabSlate-dev/TabSlate.git
cd TabSlate
bun install
bun run build

Then open chrome://extensions, enable Developer mode, choose Load unpacked, and select the .output/chrome-mv3 folder the build created. Microsoft Edge uses the same Chromium extension format, so the same unpacked folder also loads from edge://extensions.

TabSlate's build scripts also include a Firefox target (bun run build:firefox); check the project's own README for the most current steps to load a Firefox build, since its output layout is not covered here.
