# shardingsphere vs ragflow

shardingsphere and ragflow share 4 technologies: Postgres, MySQL, Redis, and OpenTelemetry. shardingsphere is written in Java and ragflow in Go.

- [apache/shardingsphere](https://seerepo.com/r/apache/shardingsphere): Empowering Data Intelligence with Distributed SQL for Sharding, Scalability, and Security Across All Databases.
- [infiniflow/ragflow](https://seerepo.com/r/infiniflow/ragflow): RAGFlow is an agent-native database: a Retrieval-Augmented Generation (RAG) engine that grew into context infrastructure.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
