Installing Neo4j

Getting started with Neo4j is easy, just install Neo4j desktop and you are ready.

Neo4j Desktop (Windows/MacOS)

You can download Neo4j Desktop from the Neo4j download page. Neo4j Desktop is bundled with a Java so you won’t need to install Java separately. If you decide to install Neo4j directly, please check the requirements here. The Community Edition of the software is free but a sign up is required. Once the file has downloaded, you can install Neo4j by following the instructions automatically opened in the browser.
