Where each one falls short

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

Tabnine

  • No published free tier as of the current pricing page, unlike several competitors that offer free individual plans
  • Pricing is higher than many consumer-focused AI coding assistants, targeting enterprise budgets
  • Now owned by Tricentis, a testing-focused company, introducing uncertainty about long-term product direction outside quality engineering use cases
  • LLM usage costs apply separately when using Tabnine-provided model access, on top of the per-seat license fee

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
