Where each one falls short

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

Postgres

  • Each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • Major version upgrades break on-disk compatibility and require a full dump and reload or the pg_upgrade tool
  • New major versions ship about once a year, so staying supported means a disruptive upgrade cycle
  • Minor releases contain only frequently-encountered bug fixes, low-risk fixes, security issues and data corruption fixes, so feature gaps are not addressed within a major version
  • There is no vendor SLA; commercial support must be bought separately from third party professional services listed by the project

Yellow.ai

  • Free plan caps chat sessions at 500 per month, then charges $0.99 per additional resolution
  • Enterprise plan pricing is not published and requires contacting sales for a custom quote
  • Basic plan pricing is not disclosed on the pricing page either, only feature details
