Where each one falls short

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

Humanloop

No published pricing for standard plans; customers must contact sales for quotes
Billing based on logs created per API call, making costs unpredictable without usage estimates
Separate charges apply from AI providers (OpenAI, Anthropic, etc.) using customer's own API keys, adding external costs

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
