Fun software but the only issue with Instant is their pricing. Once they gain adoption, I expect them to significantly raise their rates, I can seen them charging over $1 per GB easily. And like with any vendor lock-in, you’re stuck paying whatever they decide to charge. Observe with caution I'd say
Why lock-in? The interface is just a conversation and the non-programmer won't know whether it's InstantDB or whatever else in the background, as that's the whole point of vibe coding. I can only see issues taking out your data into another system, but even that can be vibe coded (can it?)
