Table of Contents

Introduction

Open source is always a hot topic among developers including software development outsourcing companies, and for good reason. Not only does it offer an alternative to costly proprietary software, but it also allows developers to peek under the hood and see how things work.

In this blog post, we’ll take a look at 10 of the best open source graph databases. Each has its own unique features and benefits, so read on to find out which one is right for you!

1. Neo4j Community Edition

Neo4j Community Edition is an open source graph database, licensed and distributed under GPL v3. It is a high performance graph db that supports Linux, Mac and Windows. This database is a perfect choice for managing data relationships. It’s a great tool for powering business applications and data-driven projects.

If for example you are working on an application project that has access to a Neo4j database running with organizational devices or even personal devices, then it is free to use the Community Edition whether or not the application is closed source.

Please note that Neo4j has a commercial version or what is commonly referred to as the Enterprise Edition. This is understandable because at the end of the day the creators need to find a way to power these resources. And so the commercial edition provides the resources to continue providing the amazing product.

(Video) Welcome to Day 4 of Miami Meetup ML/AI Meetup Week! 🤗

The good part is that for a limited number of users, the commercial edition is available at no cost. Startups with a staff count of less than 50 can contact Neo4j and request a free Startup License. Single users can also get a free license for development work.
