Ask HN: What Webinar Service to Use?

Our small company usually organizes &#x27;events&#x27; (dinners, visits of particular locations, etc..) for around 30 people in France.<p>Before the lock down, an &#x27;event&#x27; would be organizing a lunch, taking people to a bus, going to see the mayor of some city, or a construction site, etc...<p>With the lock down going on, we need to switch to digital events.<p>Here is what we are looking for:<p>- a way for people to register (for free) on future events&#x2F;webinars - no need to install a software (100% web based) - webinar recordings - multi presenters with microphone&#x2F;webcam - ask questions to presenters via a form<p>The only tool I trialed is webinarninja with seems great but I&#x27;m looking to test alternatives...<p>What do you use ?<p>Thanks !
