The short version

  • Each has a real cost: Apache Solr xML-heavy configuration and a developer experience that feels dated beside newer engines; Directus free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence
  • They diverge on capability: Apache Solr covers Lucene-based indexing, Directus covers REST API.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Apache Solr

  • XML-heavy configuration and a developer experience that feels dated beside newer engines
  • SolrCloud depends on ZooKeeper, adding a component Elasticsearch removed years ago
  • Smaller mindshare now, so newer tutorials, hiring and integrations favour Elasticsearch
  • Considerably heavier than a purpose-built application search engine

Directus

  • Free permissive use of the self hosted product is limited to organisations under $5M annual revenue with fewer than 50 employees, so crossing either threshold turns a free dependency into a paid licence
  • The free Core tier is a hard limit of 3 seats, 25 collections and 5 flows
  • The Team plan is $499 a month billed annually, or $599 monthly, with extra seats at $50 each
  • Team caps collections at 50, expandable to 100, and flows at 20
