I think I’ve tried 5 different graph database libraries in the last two days and not a single one has been able to connect to a remote/local db. All sorts of wonderful errors, db connection genservers crashing on MatchErrors, library only supports version 4.2 of db and the only ones offered now are 5+, etc.
Perhaps it’s because I’m using 1.14.5/otp26, but it seems more that many of these libraries are just no longer actively maintained.
Perhaps it’s a sign from the Ecto gods that I shouldn’t use a graph db in my project.
Anyway, is anyone actively using elixir with graph databases? If so, what’s your stack?
Side note: attempting to debug and troubleshoot said errors has taught me a significant amount of valuable insights into how elixir, mix, libraries, config all work together… so that is a big plus! Also, why it’s important for a library to include tests

I guess you refer at least to Neo4J. In the past, I did some experiments using bolt_sips, but as you say, it seems not to have been updated for Neo4J version 5.*.
It is indeed a pity that this is happening.
Did you try the other options provided in Exploring Graphs with Elixir?

I’m currently working on a new driver for neo4j that will support v 5+. I’m still ironing out a few things but I hope I’ll be able to release it by the end of June or so.
In the mean time neo4j v 3 and v 4 can still be downloaded. If you don’t use the commercial version, the feature set is rather stable.

Hello! I’ve been working on a fork of Bolt Sips for the past 3 months. You can find the project at:
https://github.com/sagastume/boltx
It provides support for the latest versions of Neo4j and Bolt. Personally, I’ve been conducting tests with Neo4j Aura.
During this period, I made numerous changes to Bolt Sips, including refactoring PackStream, protocol, socket, and more. The idea behind these changes is to make the implementation as simple as possible, making it easy to adapt to future modifications.
Feel free to try it out and let me know if everything is working smoothly
Compatibility with Neo4j versions: 3.0.x/3.1.x/3.2.x/3.4.x/3.5.x/4.x/5.9 - 5.13.0
Compatibility with Bolt versions: 1.0/2.0/3.0/4.x/5.0/5.1/5.2/5.3/5.4

I’ve added precompiled versions of kuzu_nif, so you can use KuzuDB without installing a Rust compiler on your computer. Attempt at adapting KuzuDB's Rust crate into Elixir via NIF, any tips/thoughts? - #19 by bgoosman. The advantage of KuzuDB is no server required. It’s all embedded.

I’ve been exploring a bunch of Neo4j, trying to get my head around Cypher for a couple weeks. I have a bunch of luck using the Boltx package;
I’m unsure if I’ll use Neo4j in the long run because I think it’s being outpaced by some of the competitors. I’m eager to see if the experience on Dgraph is more mature, and I came across Tinkerpop as a unified ecology for all of these graph explorations. This page on Tinkerpop seems to index all of the modern graph DB options:
Chime in if you are using graph DBs in 2025, I’d be glad to see if there could be LiveBook smart cells someday soon.
