airflow runs away with it 4–0 on popularity and shipping momentum. Stats only — numbers straight from GitHub, no AI verdict.
Apache Airflow - A platform to programmatically author, schedule, and monitor workflows
An orchestration platform for the development, production, and observation of data assets.
Each axis is scaled to the bigger of the two — the leader always reaches the edge. It shows who leads on each dimension, not by how much; hover an axis (or read the bars) for the real numbers.
Bars are scaled within each row — they compare the two repos on that metric, not across metrics. Size rows (lines of code, open issues, languages) are facts, not victories, so they are never scored. Shipping counts show “—” while GitHub warms its weekly stats cache.
apache/airflow dominates the scoreboard
apache/airflow is running laps around dagster-io/dagster with commanding leads across every momentum metric: nearly 3x the stars, 8x the forks, and a jaw-dropping 10x more shipping volume in the last month. With 7,937 commits year-over-year versus 3,078, apache/airflow is operating at a fundamentally different pace and scale—this isn't even close.
