The short version

  • Each has a real cost: Safari it runs only on Apple operating systems; there has been no Windows build since 2012 and none for Linux or Android, so any team that must verify Safari behaviour has to buy Mac hardware or rent it from a device cloud, which is a line item Chrome and Firefox do not create.; Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation
  • They diverge on capability: Safari covers WebKit engine, Swagger UI covers OpenAPI rendering.
  • 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.

Safari

  • It runs only on Apple operating systems; there has been no Windows build since 2012 and none for Linux or Android, so any team that must verify Safari behaviour has to buy Mac hardware or rent it from a device cloud, which is a line item Chrome and Firefox do not create.
  • Safari's version is bound to the operating system's version, so a Mac that has fallen off the supported macOS list stops receiving Safari updates altogether; the browser's security life is the machine's OS life, roughly three years of updates after the last major release it can run.
  • Distributing an extension means packaging it inside a signed macOS application and shipping it through the App Store with a paid Apple Developer Program membership, which makes a small internal or single-team extension impractical.
  • Automated testing uses safaridriver, which runs on macOS only, has no headless mode and permits one session per machine, so Safari coverage in CI means real Macs in the pipeline rather than containers, and it does not parallelise the way Chromium does.
  • Web platform features generally land in WebKit later than in Blink and Gecko, so Safari's current support is in practice the compatibility floor for any project, and a feature you can use everywhere else may be a year away here.
  • Enterprise management is thin: configuration profiles cover a modest set of settings with nothing comparable to the several hundred administrative policies Chrome and Edge expose, so a managed fleet cannot control Safari to the same degree.

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result

Answered from the vendors’ own pages

Safari: Can I run Safari on Windows or Linux?

No. The last Windows version was Safari 5.1.7 in 2012 and it is long unsupported. There has never been a Linux build. Testing Safari requires macOS, either your own or a rented cloud device.

Swagger UI: Is Swagger UI free?

Yes, open source under the Apache 2.0 licence. SmartBear sells commercial SwaggerHub separately.

Safari: How do I test my site in Safari without a Mac?

Through a cloud device farm such as BrowserStack, Sauce Labs or LambdaTest, which run real macOS and iOS instances. There is no reliable local emulation, because other browsers on Windows and Linux do not use WebKit.

Swagger UI: What is the difference between Swagger and OpenAPI?

OpenAPI is the specification format; Swagger is the toolset around it, including Swagger UI. The specification was renamed from Swagger to OpenAPI in 2016.

Safari: Are other iPhone browsers really different from Safari?

Historically no: Apple required all iOS browsers to use WebKit, so Chrome and Firefox on iPhone were interface shells around Safari's engine. The EU's Digital Markets Act now permits alternative engines, but adoption is limited, so in practice iOS testing still means WebKit.

Swagger UI: Can Swagger UI make real API calls?

Yes, through its try-it-out control, though authentication and CORS configuration often mean it is disabled for production APIs.

Safari: Why does Safari not get a new version on my old Mac?

Safari ships with the operating system. When a Mac can no longer run a macOS version that Apple still updates, Safari stops updating too, including its security fixes.

Safari: What does it cost?

Nothing. It is included with Apple operating systems. Private Relay requires an iCloud+ subscription, and publishing an extension requires a paid Apple Developer Program membership.
