Zef is an open source, data-oriented toolkit for graph data. It combines an in-memory graph database, versioned data, streams, Python query operators, effects handling, and GraphQL to make developers more productive. Create your first graph in a few lines:
An in-memory, immutable database means fully versioned graphs out-of-the-box. Time travel with ease to any previous time slice.
Write queries or pipelines directly in Python with a pre-built library of lazy operators. Work with your graphs like local data structures.
Automatically generate a GraphQL schema and explore with the GQL playground. Launch a GraphQL server with just a few lines of code.
ZefHub automatically stores, synchronizes, and distributes graphs across its network in real-time. Any update on a graph will be mapped almost instantaneously into the local memory of all other machines with graph access.
Access storage and real-time, distributed infrastructure instantly. No config or maintenance needed, so you can focus on development.
Send your graph’s UID to another ZefHub user. Others with access will see all graph changes happening on their local machines, in real-time.
Pull graphs onto any machine’s local memory. See all subsequent updates in real-time or lock the graph onto a specific time slice.
Move from whiteboard to prototype to production in just days. With no separate query language, no ORM, versioned history out-of-the-box, and hassle-free infra, experience smoother development and a data model that’s as close to the real-world as ever before.
