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.; Prettier inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults

- An all-Apple household or team that wants tabs, passwords and passkeys to follow them across devices without a third-party accountnot Prettier
- Privacy-conscious users on iCloud+ who want tracking protection and Private Relay working by default rather than through extensionsnot Prettier

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.
Prettier
- Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
- Developers must format entire files rather than selective line ranges in some contexts
- Limited language support compared to some alternatives, though it covers major languages

- What is Safari best used for?
- Safari is most often used for getting the longest battery life out of a macbook, where the difference against chromium browsers is hours rather than minutes, debugging a site on a real iphone or ipad, which requires safari's web inspector connected over usb from a mac, an all-apple household or team that wants tabs, passwords and passkeys to follow them across devices without a third-party account, privacy-conscious users on icloud+ who want tracking protection and private relay working by default rather than through extensions. Of those, getting the longest battery life out of a macbook, where the difference against chromium browsers is hours rather than minutes and debugging a site on a real iphone or ipad, which requires safari's web inspector connected over usb from a mac are not what Prettier is typically brought in for.

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.
Prettier: Is Prettier free and open source?
Yes, Prettier is completely free and open source, available as an npm package with no licensing costs or subscriptions.
SourceSafari: 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.
Prettier: Can Prettier be integrated with ESLint?
Yes, Prettier integrates with ESLint by disabling ESLint formatting rules via eslint-config-prettier, allowing both tools to work together with Prettier handling formatting and ESLint handling code quality.
SourceSafari: 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.
Prettier: Does Prettier support configuration customization?
Prettier is intentionally opinionated with limited configuration options to enforce consistency. You can create a .prettierrc file for basic customization, but Prettier does not support extensive rule customization like ESLint.
SourceSafari: 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.
