Top alternatives to Apache Solr

Full rankings: Algolia alternatives

In its own words

The project's README opens: "Solr is the blazing-fast, open source, multi-modal search platform built on Apache Lucene. It powers full-text, vector, and geospatial search at many of the world's largest organizations."

Why it ranks here

Health score explained

Apache Solr scores 68/100, #12 of 16 in Search Engines: 399 commits in the last 90 days earn 35.0 of 35 points, the absence of a tagged release forfeits all 25 release points, 1,693 stars add 12.9 of 20, an active, unarchived repository keeps 10 and Docker support adds the final 10. That places it in the slowing band (40 to 69). The biggest shortfall is release recency, worth 25.0 more points.
