Protomaps is a hugely important development in mapping. I switched from spending time and cash managing and hosting a Geoserver to putting all my map layers in a cheap shared web hosting with literally zero maintenance
I can’t speak highly enough about Protomaps. Took my bill from $200-300+ in my high traffic months to something like <$5/mo. Relatively easy to get started with as well. I’ve been super happy with it.
