We're fans of LucianoGanga's project (and of Chromeless, Doffy, Chrominator, Chromy, Navalia). I can tell you from personal experience that dealing with the raw DevTools Protocol isn't ideal for a developer writing an automation script, so it's clear there's demand for libraries with this higher-level API.
Would love to know if there's a feature parity concern you have or what you'd like to see from puppeteer (or any of these projects). (My personal feature unicorn: generate not a static screenshot but a proper video of a page session)
Chromeless allows for the setting of cookies. I noticed in an issue for Puppeteer that it wasn't seen as a high priority. Our use-case (session based cookies) rely on a cookie being set in order for our PDF screenshots to work.
Any chance you could give us some insight on when this may be available?
We're mainly using these things for screenshots of existing corporate intranet tools that are then surfaced to slack. Headless chrome is finally giving us screenshots that are actually authentically what you would actually see on the screen. PhantomJS came close but still has issues.
