The short version

  • Each has a real cost: Orange orange is licensed under the GNU General Public License version 3, so distributing modified or derived software requires releasing the source under the GPL; PostgreSQL requires manual scaling across multiple machines for very large deployments
  • They diverge on capability: Orange covers Visual programming, PostgreSQL covers ACID Compliance.
  • Prices and features above were last checked on 30 August 2026.
