PixelRAG alternatives

StarTrail-org/PixelRAG (10k stars, +137 this week): https://arxiv.org/abs/2606.28344. The end of web parsing. The beginning of scalable pixel-native search. link: https://pixelrag.ai/.

Below are 5 other RAG / vector repos tracked by OSS Radar that share at least two GitHub topics with PixelRAG, ordered by how many topics overlap, 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.
