Serious answer: limiting to just Open Source: JanusGraph, DGraph, Apache AGE, HugeGraph, MemGraph and ArcadeDB all meet that criteria.

What is open source and what is a graph database are both hotly debated topics.

Author of ArcadeDB critiques many nominally open source licenses here:

What is a graph database is also relevant:

  - Does it need index free adjacency?
  - Does it need to implement compressed sparse rows?
  - Does it need to implement ACID?
  - Does translating Cypher to SQL count as a graph database?

Overwhelmed by the sheer number of graph databases? I released a new site this week that lists and categorises them. https://gdb-engines.com

Knowing if it is embeddable or server would be nice in that table

Yes, I have the "embedded" kind in there but a dedicated column would be nice. Thanks!

Did you generate the list using an LLM?

I was inspired by https://arxiv.org/abs/2505.24758 and collated their assessment into a table and then just kept adding databases :)

Claude helped a lot but it's all reviewed and curated by me.

Totally agree, wrote something similar last year: https://cjlm.ca/posts/it-feels-like-gambling/

What a genuine read. And it is kinda the whole reason why i started blogging (shameless plug: stupid-ideas.com). You never git gud if you never start. And you innevitably look stupid to some people when starting.

On the topic of Yoto I made an app[0] that helps you load audio from Youtube into playlists

Nice! Yoto + YouTube audio is a clever combo. Will check it out.

Very impressive blogpost. No wonder it took 6 months. Makes me think I need to step up the game with my photo ASCII art compositor, printscii.com
