When to Use Chrome over Chromium
Browserless defaults to Chromium binaries. Chrome binaries include additional proprietary codecs that Chromium does not ship with.
If a website shows a "browser not currently supported" message, the site likely requires codecs unavailable in Chromium. Switch to Chrome when:
- Accessing streaming platforms (Twitch, YouTube, Netflix)
- Using video conferencing tools
- Targeting sites that explicitly require proprietary codecs
Default (Chromium):
wss://production-sfo.browserless.io?token=YOUR_TOKEN
Chrome (with additional codecs):
wss://production-sfo.browserless.io/chrome?token=YOUR_TOKEN
