Plane — design system & UI screens

Productivity · 1 screen · 13 sections · https://plane.so/

A product for project management and knowledge management for teams and agents. The landing page features a full-width hero section with a screenshot of the dashboard interface, followed by stacked sections showcasing key features: real-time collaboration views, project tracking and organization capabilities, integration ecosystem, reporting and analytics, and knowledge base functionality. Each section uses alternating light and dark backgrounds with paired imagery and copy blocks laid out in two-column grids.

Decoded design system

Plane's decoded design system: background #F7F7F8, text #1D1F20, accent #006399, link #006399, primary #006399; type scale h1 58px / h2 44px / body 16px; 8px spacing base; 8px base radius. The single interactive/action color is #090B0C — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.
