The best open-source database software for graphs

A graph database is a type of database that stores data and depicts it using graph structures, such as nodes, edges, and properties, in order to facilitate semantic queries. The data items in the system are linked to a graph that consists of nodes and edges. The edges represent the relationships between the nodes. The graph is a crucial component of the system.

These relationships instantaneously connect the data that has been stored and, in many cases, retrieve it all with a single operation. The ease with which one can query relationships in the database is due to the fact that they are kept there indefinitely. Graph databases are able to present interconnections in an effortless manner, which is important for information that is heavily interconnected. The best open-source database software for graphs.

Which are the finest free graph databases, and where can I get them?

  • Neo4j
  • Dgraph
  • Tigergraph

The list that follows contains reviews written by actual customers of the top free graph database solutions currently available on the market. To qualify for inclusion on this list, in addition to being a free application, you must also meet the following requirements:

Offer data storage

The data should be stored and organized using a topographical schema.

Let people retrieve data using a querying language


Neo4j is an open-source graph database that demonstrates the connections that exist between different individuals, processes, and systems. This provides businesses with the ability to make decisions that are driven by data. By default, Neo4j keeps data related to one another, which makes the data much simpler to understand. The property graph model can also be utilized by businesses in the development of machine learning and artificial intelligence models.

Cypher Query language is a highly effective declarative query language, and Neo4j utilizes it. It constructs and retrieves data associations without requiring complex queries such as SQL Joins to function properly.

Additionally, the platform makes it possible to do high-performance graph searches on enormous datasets. Despite the fact that the graph database is at the heart of Neo4j, the platform also provides tools for analytics, data discovery, and application development. High availability, online backup, and data modeling that is “whiteboard-friendly” are some of the essential advantages offered by the database.

The following are some features of Neo4j:

To facilitate the creation of Java applications, support is provided for both the Cypher API and the Native Java API.

A built-in web application for the Neo4j browser is provided by the platform, allowing users to build and retrieve graph data.

It is possible to export query data in XLS and JSON format respectively.

What users like:

“For ontology-based knowledge base generation jobs, I’ve utilized Neo4j. In my experience, the graph-based data format offered by Neo4j is the one that works best for undertakings of this nature. Aside from that, Neo4j is simple to understand and straightforward to use.

What users don’t like:

“Depending on the volume of the data, it may be difficult to visualize how the data is connected. Additionally, if an information system involves the sorting of data, it is possible for this activity to be pricey.

The dgraph

Dgraph is a graph database system that utilizes a solitary development paradigm for its schema. Users are able to design a schema with the help of the tool, deploy it, and obtain quick access to the database and API without having to write any code.

Dgraph gives users the option to select either GraphQL or DQL as their query language, making it possible for users who have no prior experience with graph databases to get started. In addition to these features, the database supports straightforward data import and data streaming, and it has the ability to simplify business logic with Dgraph Lambda.

Dgraph has the following features:

Users of the software have the ability to make changes to the schema at any moment, which causes the graph to be updated accordingly.

It supports a variety of open standards, including gRPC, Protocol Buffers, Go contexts, and Open Census integration for distributed tracing, among others.

The authorisation system is already included into Dgraph GraphQL. Users are granted the ability to label the schema with rules that regulate who has access to the data and who is authorized to make changes to it.

What users like:

“Scalability is a fundamental component of the Dgraph itself. It’s a graph database that comes pre-packaged with GraphQL already installed and ready to use. It is simple to interpret the schema and construct your queries using the GraphQL web user interface.

What users don’t like:

“In comparison to alternative solutions, storing a graph in Dgraph consumes a significant amount of RAM. The managed offering does not give all of the features that may be achieved through the use of its Kubernetes cluster. The management needs to be handled either by yourself or by the organization’s DevOps team.


Tigergraph is a scalable graph database with an emphasis on the commercial market. The tool is capable of managing any quantity or complexity of datasets in real time, and it provides customers with all of the capabilities that they anticipate receiving from an enterprise-level graph database system.

The scalable graph database offered by Tigergraph provides analytics tools that are easy to use, even for those who lack the necessary level of technical expertise, and also offers reliable solutions. It is possible to scale it according to the rising demands of the organization, and it provides graphs with trillions of edges that can do real-time analytics.

Tigergraph has the following features:

When it comes to doing high-performance analytics and graph operations, the industry standard is the query language known as GSQL. Tigergraph leverages this language. It has high-level syntax, “Turing completeness,” and built-in parallelism, all of which contribute to a brisk development pace and excellent performance.

GraphStudio is Tigergraph’s graphical user interface (GUI), which combines all parts of graph data analysis into a single, highly usable tool. Although GraphStudio’s GUI is simple, its strength is immense.

By processing bulk loads at a rate of 100 GB per hour per node and giving real-time live updates, the platform gives users control and makes it possible for them to rely on the platform.

What users like:

“When it came to linking data using machine learning, Tigergraph was a very helpful tool. It helps push our data points so that we may make better decisions for our business.”

What users don’t like:

“At other times, however, it can move at a snail’s pace.”
