WebMerge - Multi-Website Feed Aggregator

Multi-site aggregator and feed collector.

WebMerge is a browser extension for Chrome, that aggregates and searches across multiple websites simultaneously. It uses AI to extract structured data from web pages and presents results in a unified, sortable feed. Features - Parallel Multi-Site Search : Query multiple websites at once in a single search - AI-Powered Data Extraction : Uses OpenRouter or Mistral AI to parse raw HTML to cleaned Markdown and then into structured items (titles, prices, images, dates etc.) - Custom Site Schemas : Define your own field schemas per site to extract exactly the data you need - Result Feed : Browse, sort, and filter aggregated results across all sites - Homepage Feeds : Pin sites as "homepage" sources and fetch their latest listings with one click - Result Cards : Customisable card layouts with drag-and-drop field ordering, per-site or per-group - Site Groups : Organise your sites into named groups and search within a specific group - Enrichments : Optionally fetch extra metadata from external APIs (e.g. OMDB for movie ratings) - Context Menu Integration : Right-click any page to add it as a new site - Custom Cookies : Pass session cookies to search on sites that require login - Chrome & Firefox : Full support for both browsers with a single codebase - Dynamic Filter Tabs : A collapsible filter bar below the site tabs lets you filter results by any categorical field (e.g. media_type, genre). Filter rows are fully dynamic : any badge-style field you add to your card layout automatically gets its own filter row with all unique values as clickable tabs - Media Type Filtering : The media_type field (e.g. Movie, Series, Game) is always surfaced as a filter row when two or more distinct values exist in the current results - Smooth Card Animations : Card hover effects (lift, scale, image zoom, ambient glow) are GPU-accelerated via compositor-only transforms, keeping animations fluid on both Chrome and Firefox - Open-Source: No user data collected or share. https://github.com/biplobsd/webmerge Limitations - Cloudflare protected sites are not supported - Sites with heavy JavaScript rendering may not work properly
