helix-foundry alternatives

HelixDB/helix-foundry (1.8k stars, +175 this week): Connect your company's data, let an agent draft an ontology over it, and load it into HelixDB as one graph you can explore and ask questions…

Below are 3 other repos tracked by OSS Radar that share GitHub topics with helix-foundry: 2 from RAG / vector sharing at least two, and 1 from other categories sharing at least three topics about what they do (platform, language and framework tags don't count), two of them niche rather than broad ones like llm, ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
