Looking for a CARTO alternative (API key change broke our shipped apps)

Dear friends, Could I ask for recommendations for an alternative to CARTO please? We've been using them for a few years, and they've now decided (seemingly overnight) to require an API key to keep using the service. I have no beef with that in principle. What stung was the complete lack of notice: most of what we've built on it is shipped in apps that are live on the Play Store and App Store, so we've been left scrambling. To be clear, we're happy to pay if that's what they need to keep the lights on. But gating everyone without a word of warning is a bit of a d*ck move, and we'd much rather move to something maintained by people you can vouch for as, well, not d*cks. Any suggestions gratefully received. Please and thank you, Neithan submitted by /u/neithan_pixelzero [link] [留言]
