Releval is an API-first platform for evaluating, tracking, and improving search relevance. Connect popular search engines like Elasticsearch, OpenSearch, Solr, Vespa, or your own custom search APIs or search pages; measure quality with standard Information Retrieval metrics; automate judgments with LLM-as-a-judge using popular providers; compare ranking changes; run evaluations in CI; and turn real user behaviour into a continuous relevance feedback loop.
