Sosse is an open-source, enterprise-grade web crawling, archiving, and search engine designed for flexibility and power. Powered by Selenium, it excels at handling JavaScript-heavy websites, enabling users to crawl, archive, and search web pages with ease. Key features include creating HTML and screenshot archives from bookmarks, browsing history, RSS feeds, or other sources, making it a robust alternative to tools like the Wayback Machine. With Sosse, teams can extract and analyze data securely, supported by a user-friendly administration interface and customizable crawl policies. Ideal for self-hosting. In this step by step guide I will show you how to install Sosse on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Sosse v1.13.0 release.
