What is Opensolr?

Managed Apache Solr hosting with built-in AI search, web crawling, analytics, and server management — production-ready in under a minute.

Opensolr is a managed cloud platform built on Apache Solr — the industry-standard open-source search engine. We handle the infrastructure, scaling, security, and maintenance so you can focus on building your product. Whether you need full-text search for an e-commerce store, AI-powered semantic search, a web crawler that indexes your site automatically, or a complete server management panel for your web projects — Opensolr has you covered. We are a small, focused team of DevOps, Linux, and full-stack developers based in Cluj-Napoca, Romania, deeply passionate about search technology and problem-solving.

Web Crawler

Site Search Without Code

Point Opensolr at any website — it crawls every page, extracts text (HTML, PDF, DOCX), generates BGE-m3 vector embeddings, detects language and sentiment, and indexes everything into Solr automatically. One script tag adds the full search UI to any site.

AI & Hybrid Search

Beyond Keyword Search
