Hi @simonb
TealCraft is a 100% react application and no server is involved except for sharing functionality.
The sharing feature can be moved to IPFS later. you are right, in the future, this can be shipped as part of Algokit, where TealCraft is connected to the local net as the networks are configurable in the TealCraft playground.
Not sure, but I don’t think AF has this on their roadmap. TealCraft is going to be open source and it makes sense to integrate it instead of starting it from scratch.
