Raphtory is an in-memory graph tool written in Rust with friendly Python APIs on top. It is blazingly fast, scales to hundreds of millions of edges on your laptop, and can be dropped into your existing pipelines with a simple pip install raphtory.

It supports time traveling, multilayer modelling, and advanced analytics beyond simple querying like community evolution, dynamic scoring, and mining temporal motifs.

Below you can see an example of these APIs and the sort of questions you can ask!


from raphtory import Graph
from raphtory import algorithms as algo
import pandas as pd

# Create a new graph
graph = Graph()

# Add some data to your graph
graph.add_node(timestamp=1, id="Alice")
graph.add_node(timestamp=1, id="Bob")
graph.add_node(timestamp=1, id="Charlie")
graph.add_edge(timestamp=2, src="Bob", dst="Charlie", properties={"weight": 5.0})
graph.add_edge(timestamp=3, src="Alice", dst="Bob", properties={"weight": 10.0})
graph.add_edge(timestamp=3, src="Bob", dst="Charlie", properties={"weight": -15.0})

# Check the number of unique nodes/edges in the graph and earliest/latest time seen.

results = [["earliest_time", "name", "out_degree", "in_degree"]]

# Collect some simple node metrics Ran across the history of your graph with a rolling window
for graph_view in graph.rolling(window=1):
    for v in graph_view.nodes:
            [graph_view.earliest_time,, v.out_degree(), v.in_degree()]

# Print the results
print(pd.DataFrame(results[1:], columns=results[0]))

# Grab an edge, explore the history of its 'weight'
cb_edge = graph.edge("Bob", "Charlie")
weight_history ="weight").items()
    "The edge between Bob and Charlie has the following weight history:", weight_history

# Compare this weight between time 2 and time 3
weight_change =["weight"] -["weight"]
    "The weight of the edge between Bob and Charlie has changed by",

# Run pagerank and ask for the top ranked node
top_node = algo.pagerank(graph).top_k(1)
    "The most important node in the graph is",
    "with a score of",


Graph(number_of_nodes=3, number_of_edges=2, number_of_temporal_edges=3, earliest_time=1, latest_time=3)

The edge between Bob and Charlie has the following weight history: [(2, 5.0), (3, -15.0)]
The weight of the edge between Bob and Charlie has changed by 20.0 pts
The most important node in the graph is Node(name=Charlie, earliest_time=1, latest_time=3) with a score of 0.4744116163405977
