Where each one falls short

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

Odoo Inventory

  • The One App Free plan covers a single app, so using Inventory alongside another Odoo app moves the account onto a paid plan
  • The Standard plan at $16.90 per user per month is restricted to Odoo Online hosting
  • Odoo.sh and on premise hosting require the Custom plan at $25.50 per user per month
  • Odoo Studio, multi company management and external API access require the Custom plan
  • Billing is per user, defined as any employee with backend access to create, view or edit documents
  • The advertised discounted rates apply for the first 12 months, after which the list rates of $21.10 and $31.90 per user per month apply

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
