Sosse

Selenium-based search engine and crawler with offline web archiving

About Sosse

Sosse is a self-hosted search engine and web crawler that uses a real browser through Selenium to index pages that rely on JavaScript, then archives them for offline browsing. It supports recurring crawls, screenshots, tags, collections, analytics, webhooks, and a REST API, storing data in PostgreSQL. Written in Python and distributed under AGPLv3, it suits archivists, researchers, and teams building a private, searchable copy of web content.
