# ragflow vs OpenMetadata

ragflow and OpenMetadata share 9 technologies: s3, Postgres, MySQL, Redis, Google, React, Model Context Protocol, OpenTelemetry, and Tailwind CSS. ragflow is written in Go and OpenMetadata in Java.

- [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.
- [open-metadata/OpenMetadata](https://seerepo.com/r/open-metadata/OpenMetadata): The Open Context Layer for Data and AI ,  OpenMetadata is the open platform for building trusted data context and business semantics for humans, AI assistants, and agents.

- 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.
