Aphrodite - Gifts of Olympus
aphrodite.sh
Develop with your data model on the client. Query and load data reactively. Replicate between peers without a central server.

Aphrodite is a schema layer whose first goal is to make P2P & Local-First software development as easy as traditional software development.

You can think of Aphrodite as an ORM of sorts that is designed for the needs of Local-First applications and P2P data transfer.
