Stem – Visual Tab Session Manager

Stem turns a crowded browser into a visual workspace. Organise tabs in colour-coded groups, put inactive tabs to sleep, and restore them when you need them. Use Outline View for fast tab management, the graph to understand relationships between pages, or split view to use both at once. Stem is designed for research, study, design and any work that develops across large and complex browser sessions. KEY FEATURES • Capture existing open tabs and native Chromium tab groups • Organise tabs across locally named windows, colour-coded groups and nested subgroups • Sleep and restore individual tabs or complete groups • Automatically capture newly opened tabs when enabled • Keep loose browsing in a visible Unsorted area • Search by page title, domain or tag • Add, rename and filter coloured tags • Explore parent-child, shared-tag and optional shared-domain connections • Move and arrange graph nodes and group territories • Use organic mesh and grid graph layouts • Move tabs and complete groups between browser windows • Switch between Outline View, graph and split views • Use light, dark or system appearance • Import and export complete JSON workspaces • Export sessions as readable Markdown files • Review the last 20 navigation entries retained for each tab LOCAL-FIRST PRIVACY Stem uses tab titles, URLs, favicons, groups, tags and navigation metadata only to organise and restore your browser workspace. Your workspace data remains stored locally on your device unless you deliberately export it. Stem does not read page content, use analytics, require an account or transmit workspace data to remote storage. Stem is developed by Botany Apps.
