The PlayStation 4 is quite the capable device, unsurprisingly able to run Linux. I recently bought a PS4 and in true developer spirit immediately began poking around the browser. To my knowledge, there's next to zero developer documentation. The best I could find was a single PDF from Sony which appears to be dated. My goal is to document what's known about the PS4's Browser.

My PS4 test setup

Version: CUH-1200

OS: 3.50

Gecko? Mozilla? Netfront? ps4 screenshot

Google's whatbrowser gives an error. ps4 screenshot reads the Gecko-Like User-Agent string. ps4 screenshot likely matches UA string by closest match, and returns Mozilla. ps4 screenshot correctly identifies the PS4 as NetFront.

NetFront is a proprietary web browser used for the PlayStation 3, PlayStation Vita, PSP, Nintendo 3DS, Wii U and Kindle E-reader. The original Netfront Browser has since been replaced by a webkit powered NetFront NX which appears to power the PS4.

Browsers Tests


Acid3 test

Sunspider 1.0.2 test: Overall score: 3203 ms using remote login (and a game left open)


PS4's fails to load

Notably, some previous users have completed the HTML5 tests; you can see the scores: here.

PS4's fails during Octane test...

The PS4's weakest link appears to be modern JS support. Unsurprisingly the PS4 isn't a strong performer. In a very uncontrolled environment with three concurrent browsers open, and roughly 25 tabs and several apps, my MacBook Pro in chrome scored a 157.8ms vs the PS4's 2929ms (Lower is better). An iPhone 6 scores roughly 326.6 ms. The big differences here are that both Chrome, Safari and FireFox use highly optimized JS engines, V8, NitroJS, and SpiderMonkey respectively. However, other users report much better SunSpider benchmarks clocking around 1027ms which places roughly at the performance of an iPhone 5 when it comes to JS. While the PS4 certainly has room for improvement but is unlikely to see massive gains as I highly doubt most people spend much time in the browser outside of gaming.

More to come...

Stay tuned; I plan to update this over time. Testing the PS4 is tedious as the remote support doesn't allow text input via keyboard.

Planned tests: weinre remote debugging, FireBug Lite, BrowserSync
