Where each one falls short

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

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

Windsurf

  • Recently rebranded to Devin Desktop, creating product identity confusion
  • Cascade agent reached end-of-life on July 1, 2026, requiring migration to Devin Local
  • Free tier quota runs out quickly for active developers, within a couple days of coding
  • Pricing increased significantly in March 2026 overhaul, moving from credit-based to daily/weekly quotas
  • OpenAI acquisition raises concerns about long-term product direction diverging from Codeium's vision
