Firecrawl describes a consensus display alongside the range of provider forecasts. That range is a useful question to bring into a lineup discussion: are the sources making similar assumptions, or does the decision depend on a disputed workload? Agreement alone does not prove a forecast will be correct, and the announcement supplies no independent accuracy test.
Its lineup workflow accepts a Sleeper username, an ESPN or Yahoo team link, or a roster screenshot. Firecrawl also says its standalone lineup page can work without an account and keeps the roster in the browser. That privacy description applies to the page as described by the company; it should not be treated as a promise covering every connected assistant or provider.
RSO adds another decision layer. Its official rules describe customizable scoring, player contracts and salary-cap consequences when guaranteed money remains. A projected-point advantage can inform a start/sit choice while a waiver or trade decision still requires the owner's actual contract obligations and league settings.
Neither the announcement nor RSO's rules describe an Alexandria integration that imports those RSO contracts or executes transactions. Owners using the research should check their own scoring and cap position before acting.
