# airflow vs logstash

airflow and logstash share 3 technologies: Apache, OpenTelemetry, and org.apache.logging.log4j:log4j-core. airflow is written in Python and logstash in Ruby.

- [apache/airflow](https://seerepo.com/r/apache/airflow): Apache Airflow - A platform to programmatically author, schedule, and monitor workflows
- [elastic/logstash](https://seerepo.com/r/elastic/logstash): Logstash - transport and process your logs, events, or other data

| Who writes it | 0.7% of its commits signed by AI. With Claude Code, GitHub Copilot, Cursor, and Devin | 0.2% of its commits signed by AI. With GitHub Copilot, Claude Code, and Cursor |
| Activity | Last push November 5, 2026, 41,804 commits, 47,376 stars | Last push November 6, 2026, 10,353 commits, 14,973 stars |
| Tests | 4,949 test files. 53.3% of its code files have a test that imports them | 474 test files. 60.2% of its code files have a test that imports them |

- 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.
