We have a Facebook group where various people create events. To make them more widely visible (not everyone has a Facebook login), we share them (read-only) via Wallflux to a Google calendar too. This is convenient for those with Google logins, but for those without, we further used to create a public version via Yahoo Pipes / RSS (again read-only, and no login of any type required).
Yahoo Pipes is now defunct, so we're looking for another free & easy way to do this. We have no server (can't install apps anywhere) or budget, so the ideal would be a web app somewhat like Yahoo Pipes, where we can simply tell people a URL and when they access it, it reads in from either the GCal or FB URLs and outputs a basic listing that everyone can view (even just the event's basic date/time/title). Most of the 'Yahoo Pipe replacements' we've seen (along with IFTTT, Zapier etc.) look too complex: we only need one function. Suggestions?
