FOSS tool for editing graph data

Is there any FOSS tool available for node/edge editing? I stumbled over neo4j commander which seems to be a nice tool for the purpose but it still isn't FOSS albeit very nicely priced. I'm running a community version of neo4j as a container and would like to find a browser based tool. Neo4j Bloom also seems to fit the bill but it's desktop based so that rules it out.

Many thanks in advance.

Hi Peter, if you're still looking for a tool, you might want to consider https://graphdraft.com/ It can run in a browser and is free.
