Forge gives you a variety of ways to store data - KVS, Custom Entities, Forge SQL, Object Store, and even remote APIs. But which one should you reach for? In this session, we'll build a small, fun Forge app and progressively layer on several options, talking through the trade-offs as we go. By the end you'll have a mental model for choosing the right primitive for your use case and a working code sample to take home and tinker with. No prior Forge experience required - just curiosity.
