Otium

A local-first browser workspace for organizing links, projects and web tools directly from your New Tab page.

Overview

A workspace inside your browser.

Otium is a local-first browser workspace built as a Chromium extension. It replaces the default New Tab page with a spatial workspace where websites, folders and projects can be organized visually.

Projects provide flexible canvases where browser-native tools can be combined with saved resources without turning the browser into a traditional dashboard.
