The short version

  • Each has a real cost: Keeper free tier is severely limited to 10 passwords on a single device; essentially a trial rather than a usable free version; Postgres each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • They diverge on capability: Keeper covers Password management, Postgres covers ACID compliance.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Keeper

  • Free tier is severely limited to 10 passwords on a single device; essentially a trial rather than a usable free version
  • Personal plan at $1.79/month is promotional pricing; regular price is higher, making budget comparison difficult

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
