# airflow vs OpenMetadata

airflow and OpenMetadata share 9 technologies: Flask, Redis, Google, Apache, Vite, React, OpenTelemetry, org.apache.logging.log4j:log4j-api, and org.slf4j:slf4j-api. airflow is written in Python and OpenMetadata in Java.

- [apache/airflow](https://seerepo.com/r/apache/airflow): Apache Airflow - A platform to programmatically author, schedule, and monitor workflows
- [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.
