Arkipelago.space alternatives

Felt is the collaborative map-making tool I want to use for everything I can. I'm a GIS nerd and contributed a lot of microPOI to OSM in my locality, but those maps never felt actionable the way I wanted them to be; taking screenshots and marking them up only goes so far. Whereas before I had to use something like a POI collection in Apple or Google Maps, Felt lets me instantly get my thoughts down and get a spatial understanding of whatever it is I’m trying to plan out, then share that with others easily. In terms of features, the clipping tool is brilliant as an annotation device because it’s so simple but so helpful. The UI is immaculate and the collaborative nature of the service reminds me of something like a geospatial FigJam. Being able to upload images and georeference them on top of the overlays you’ve already got going is so useful for showing things on the ground. Felt is my favorite map data tool and it's already helping me reduce my desire to learn something complicated like QGIS or pay a huge fee for something like ArcGIS. I absolutely recommend it to anyone looking to get something spatial done.
