Sightline is a Next.js web application for discovering and analyzing real-world infrastructure using OpenStreetMap data. It provides a search interface that accepts natural language queries (e.g., 'telecom towers in karnataka') or structured syntax (e.g., 'type:telecom operator:airtel region:karnataka'). The application uses Nominatim for geocoding to convert location queries to bounding boxes, then queries the Overpass API for matching OSM assets. Results are displayed on an interactive Leaflet map with marker clustering and in a filterable list. The architecture features a clean separation between frontend React components, backend API routes for search and geocoding proxying, and utility libraries for query parsing, caching, and API interactions. The application implements proper rate limiting, timeout handling, fallback API endpoints, and efficient caching to respect external service limits while providing a responsive user experience.
This repository is a curated collection of over 1000 OSINT (Open Source Intelligence) tools, services, and resources organized by category. It is not a software application itself, but a static list compiled in a README.md file with occasional supporting HTML pages for specific searches (court records, graves, hashtags). The repository contains no executable code, libraries, or frameworks—it serves purely as a reference directory. Weekly update HTML files track additions over time. While popular (8700+ stars), the repository offers zero reusable software components, architecture, or data pipelines. It is a flat list of links with brief descriptions, useful for human browsing but not for programmatic consumption or reuse as a codebase.
