This is a full-stack web application for performing open-source intelligence (OSINT) analysis on any website. The system runs 40+ checks encompassing DNS, SSL/TLS, HTTP security headers, mail configuration (SPF/DKIM/DMARC), social media presence, trackers, blocklists, threat feeds, carbon footprint, tech stack, and more. The frontend is built with Astro and React, featuring a reactive results view with a masonry grid, advisory panel, and progress bar. The backend is a Node.js Express server (also serverless-friendly) with individual API handlers per check, wrapped in a common middleware layer for error handling, rate limiting, and skip logic. The application is designed for self-hosting and supports deployment to Vercel, Netlify, Docker, Render, and Fly.io. It relies on many external sources (DNS, WHOIS, SSL Labs, HIBP, Google Safe Browsing, Shodan, etc.) and uses Puppeteer/Chromium for headless browser tasks. The codebase demonstrates a clean modular architecture, reusable UI components, and a novel analysis rule system that transforms raw data into structured findings with severity levels.

Dashy is a self-hosted dashboard application that serves as a customizable startpage and service monitor for homelabs and server infrastructure. In production, it aggregates links to internal and external services, displays live widgets (weather, system metrics, crypto prices, news, etc.), and performs HTTP/ICMP status checks to indicate service health. The application is configured entirely via a YAML file (conf.yml) that defines pages, sections, items, widgets, authentication providers, themes, and layout options. Users can interact through multiple views: a default grid, a workspace with sidebar and iframe content, and a minimal tabbed view. The system also includes an interactive configuration editor, cloud backup/restore with AES encryption, and full REST API for programmatic management. Architecturally, Dashy is a full-stack web application with a Vue 3 frontend (built with Vite) and a Node.js Express backend. The frontend handles rendering, theming, localization (30+ languages), and client-side authentication flows (OIDC, Keycloak, header auth, built-in users). The backend provides endpoints for config saving, CORS proxying (with SSRF protection), status/ping checks, and optional REST API. Deployment is Docker-first, but bare-metal, cloud (Netlify, Render), and static hosting are also supported. The codebase is organized into reusable mixins (WidgetMixin, ThemingMixin, HomeMixin), custom Vue directives (DragSort, Tooltip, LongPress), and a schema-driven configuration system that powers both validation and the CodeMirror-based YAML editor. Key data flows include: (1) configuration loading from file and localStorage, merged by the ConfigAccumulator; (2) widget data fetching via the CORS proxy or direct API calls, with standardized error handling and update intervals; (3) authentication token exchange and session management across client and server; (4) status checks that update item indicators in real-time. External dependencies are limited to Node.js, Vue 3, Express, and a handful of widget-specific APIs (OpenWeatherMap, CoinGecko, etc.), all of which are optional and configurable. The project is purely an application with no data research or analytics components.

Awesome Privacy is a curated directory of privacy-respecting software and services, accessible via a public website and API. The repository centers around a single source of truth YAML file (`awesome-privacy.yml`) that catalogs tools across categories like Essentials, Communication, and Security Tools. This data is processed by a Python-based toolchain (`lib/`) for validation, changelog generation, and README updates, while a modern web frontend (`web/` built with Astro and Svelte) provides interactive browsing and search, and a TypeScript API backend (`api/` using Hono) serves JSON endpoints and enriches service data with metadata from external sources like GitHub, Docker Hub, and app stores. The architecture cleanly separates data, processing, and presentation layers, with robust caching, rate limiting, and authentication in the API, and client-side search via MiniSearch in the web app. The project emphasizes maintainability through automated PR checks, dependency management, and clear contribution guidelines, though it relies on numerous third-party APIs for enrichment, introducing potential external dependency risks.
