Where each one falls short

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

Open edX

  • No license fees for software but requires separate spending on hosting, infrastructure, and maintenance
  • Customization and support from third-party providers requires additional investment

Weaviate

  • The free tier caps at 100,000 objects, 1 GB of memory and a single collection
  • Billing is per million vector dimensions rather than per record, so wider embeddings cost proportionally more for the same object count
  • Premium is a prepaid contract starting at $400 a month rather than pay as you go
  • Storage rates do not fall consistently with tier, and Premium Dedicated is $0.1505 per GiB against $0.12 on the cheaper Flex plan
  • The Query Agent is metered separately, free to 1,000 requests a month and $30 a month plus overage beyond
