Neo4j replication alternative to Neo4j Enterprise edition?

It seems Neo4J High Availability is only available for the Enterprise edition which is paid- is there another alternative to achieve replication without that module? (i.e. without cost). Thanks for any help!

Update:

This answer has changed. Neo4j is now open core, so the Enterprise code is no longer dual-licensed - only the commercial license option remains.

You can find more details here: https://neo4j.com/open-core-and-neo4j/

Original Answer:

Enterprise is available as quid-pro-quo - if you put your code out under an open source license, then you get access to the open source Neo4j Enterprise free of charge. However, if you are closed source, Neo Tech charges a license fee. This fee is determined by your needs and your ability to pay - if you are a small outfit with no venture capital, it's still free, and then the licensing cost increases as your ability to pay back to the development of Neo4j increases.

If your application is open-source as you mention, then you are free to use Neo4j Enterprise without paying for it, simply download it at neo4j.org.

Actually Neo4j Enterprise is free under the open source AGPLv3 license.

Neo4j Inc can't modify the terms and still call it AGPL.

If you use Neo4j Enterprise as a server (like most people do) and communicate with it via its REST API or any of the official BOLT drivers then you never trigger AGPL's copyleft requirements.

In other words - the software that connects to it does not have to be open sourced.

You can download Neo4j Enterprise open source licensed binaries up to version 3.2.x from dist.neo4.org. The links for the windows and unix packages are below. (Replace the version number for specific versions)

http://dist.neo4j.org/neo4j-enterprise-3.2.8-windows.zip

http://dist.neo4j.org/neo4j-enterprise-3.2.8-unix.tar.gz

If you want Neo4j Enterprise 3.3.0 and on under it's free open source license, then you can build them from source like we do for our US government clients, or just grab them from our free distribution site.

Check out the blog post if you want to understand why this has happened.
