GRAPH DATA
FOR A DISTRIBUTED, REAL-TIME WORLD

The easiest graph data experience for Python developers

A Python graph data experience with Zef

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:

DEVELOP WITH ZEF

Fully versioned graphs

An in-memory, immutable database means fully versioned graphs out-of-the-box. Time travel with ease to any previous time slice.

Query locally using Python

Write queries or pipelines directly in Python with a pre-built library of lazy operators. Work with your graphs like local data structures.

Native GraphQL support

Automatically generate a GraphQL schema and explore with the GQL playground. Launch a GraphQL server with just a few lines of code.

Distributed, real-time infra with ZefHub

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.

DISTRIBUTE WITH ZEFHUB

Infra with 1 line of code

Access storage and real-time, distributed infrastructure instantly. No config or maintenance needed, so you can focus on development.

Share graphs with others

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.

Retrieve graphs instantly

Pull graphs onto any machine’s local memory. See all subsequent updates in real-time or lock the graph onto a specific time slice.

From prototype to production in days

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.
