Vendor lock-in is severe — the client SDK is so deeply embedded in your app that migrating away took my team two full weeks+199

Pricing can spike unexpectedly because reads are charged per document, and a single inefficient query can cost dollars instead of cents+176
There's no way to do schema migrations or version your data model, so evolving your data structure over time is a manual nightmare+134
