The short version

  • Only Swagger UI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation; Zabbix Cloud billed by NVPS (new values per second) rather than by number of monitored hosts, so cost scales with metric volume: Nano starts at $50/month for 50 NVPS and 2xLarge reaches $5,000/month for 10,000 NVPS
