Buffer analysis in free web map software – August 18, 2022 at 02:53PM

Hi, I’m working on a project where the client would like to perform a buffer analysis around certain points on a web map. The client doesn’t have an ESRI account, so I’m looking for a free option. I can’t find a way to create buffers through either the qgis2web plugin or a free ArcGIS Online account. Is there a way I could create a free web map that allows the client to do a buffer analysis, or would they have to download QGIS and do an analysis themselves?

Thanks!
