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

Appsmith

  • The free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories
  • Workflows, custom roles and audit logs all require the Business plan at $15 per user per month
  • SAML and OIDC single sign-on need Enterprise, which starts at $2,500 a month with a 100 user minimum
  • Embedding an app privately is Enterprise only; the lower tiers embed publicly
  • Managed hosting is an Enterprise add-on rather than an included option
