API

launch accepts all the arguments accepted by firefox.launch or launch methods of other browser types and some additional arguments defined below:

Argument	Default Value	Description
spm_apikey	undefined	Zyte Smart Proxy Manager API key that can be found on your zyte.com account.
spm_host	http://proxy.zyte.com:8011	Zyte Smart Proxy Manager proxy host.
static_bypass	true	When true Zyte SmartProxy Playwright will skip proxy use for static assets defined by static_bypass_regex or pass false to use proxy.
static_bypass_regex	/.*?\.(?:txt|json|css|less|gif|ico|jpe?g|svg|png|webp|mkv|mp4|mpe?g|webm|eot|ttf|woff2?)$/	Regex to use filtering URLs for static_bypass.
block_ads	true	When true Zyte SmartProxy Playwright will block ads defined by block_list using @cliqz/adblocker-playwright package.
block_list	['https://secure.fanboy.co.nz/easylist.txt', 'https://secure.fanboy.co.nz/easyprivacy.txt']	Block list to be used by Zyte SmartProxy Playwright in order to initiate blocker enginer using @cliqz/adblocker-playwright and block ads
headers	{'X-Crawlera-No-Bancheck': '1', 'X-Crawlera-Profile': 'pass', 'X-Crawlera-Cookies': 'disable'}	List of headers to be appended to requests

Notes

• Some websites may not work with block_ads and static_bypass enabled (default). Try to disable them if you encounter any issues.

• When using the headless: true mode, values generated for some browser-specific headers are a bit different, which may be detected by websites. Try using 'X-Crawlera-Profile': 'desktop' in that case:

    const browser = await chromium.launch({
        spm_apikey: '<SPM_APIKEY>',
        headless: true,
        headers: {'X-Crawlera-No-Bancheck': '1', 'X-Crawlera-Profile': 'desktop', 'X-Crawlera-Cookies': 'disable'}
    });

• When connecting to a remote Chrome browser instance, it should be launched with these arguments:

--proxy-server=http://proxy.zyte.com:8011 --disable-site-isolation-trials
