Blueprint is Palantir's React-based UI toolkit, distributed as a set of modular NPM packages, designed for building complex, data-dense desktop web interfaces. It ships polished components including an interactive spreadsheet-like table, date/time pickers, selects, and an extensive icon set with a cohesive design system.

A file-format specification and CLI/library from Google Labs for describing a design system to coding agents. A DESIGN.md combines machine-readable design tokens (YAML front matter) with human-readable rationale (markdown prose), and the tooling lints, diffs, and exports those tokens to formats like Tailwind and W3C DTCG.

Appsmith is an open-source low-code platform for building internal tools — dashboards, admin panels, CRUD apps, and workflow tools — by dragging UI widgets onto a canvas and wiring them to databases and APIs with JavaScript bindings. It can be self-hosted via Docker, Kubernetes, or AWS, or used as a managed cloud service.

Onlook is an open-source visual editor for React apps that pairs an AI agent with a design-tool-style canvas, letting you edit a live Next.js/TailwindCSS app visually and in code while the changes write back to the actual source. It positions itself as a "Cursor for designers," bridging the gap between design and front-end development.

Adobe's family of React libraries for building accessible UIs: React Spectrum (styled components implementing Adobe's design system), React Aria (unstyled accessible components and hooks), React Stately (cross-platform state management hooks), and framework-agnostic internationalization utilities.

VvvebJs is a dependency-free, vanilla JavaScript drag-and-drop page builder library built around Bootstrap 5, letting users visually assemble HTML pages from components, sections, and blocks with live code editing, undo/redo, and server-side save/export via included PHP or Node scripts.

Podman Desktop is a cross-platform Electron/TypeScript desktop GUI for building, running, and managing containers, pods, images, and Kubernetes workloads. It installs and keeps Podman up to date, works across multiple container engines (Podman, Docker, Lima, crc), and is extensible through a plugin system.
