Data & Analytics

4.4 / 5.0

Milvus is a cloud-native, open-source vector database built to handle billions of vectors at enterprise scale. Originally developed at Zilliz and donated to the LF AI & Data Foundation, it powers semantic search, recommendation systems, and AI applications at companies like Walmart and Shopee. Milvus supports multiple index types, GPU acceleration, and a distributed architecture - making it the most scalable open-source vector database available.

Best for: Enterprise engineering teams building billion-scale vector search systems for recommendation engines, semantic search, and AI applications

Data & Analytics

4.3 / 5.0

Snorkel AI is a programmatic data labeling platform that uses weak supervision - allowing ML teams to label training data using heuristic labeling functions instead of manual annotation. Its Snorkel Flow platform enables domain experts to write labeling rules that programmatically generate training labels, reducing annotation costs by 10-100x. Used by Google, Intel, and government agencies.

Best for: Enterprise ML teams needing to label large datasets cost-practically using programmatic weak supervision instead of manual annotation
