WebMerge - Multi-Website Feed Aggregator

About

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
