[airflow](https://airflow.apache.org/) reports 46k GitHub stars, 18k forks, and 1.9k open issues, last pushed Aug 9, 2026. [kestra](https://go.kestra.io/home) has 28k stars, 2.9k forks, and 549 open issues, last pushed Aug 19, 2026.

See the comparison table for live GitHub stats and shared categories. ### When should I choose airflow over kestra? Choose airflow over kestra when airflow is primarily Python; kestra is Java; Tags unique to airflow: airflow, apache, dag, mlops; If you need to model complex workflow dependency graphs with Directed Acyclic Graphs (DAGs). ### When should I choose kestra over airflow? Choose kestra over airflow when kestra is primarily Java; airflow is Python; Requirements: Min 2 GB RAM; Requires Docker; Requires Docker to deploy using the provided Terraform module on Google Cloud.; Strongly recommended for use in Java-based environments due to its native support.; Tags unique to kestra: ai-agents, control-plane, data-orchestration, devops; When you are working on mission-critical applications and need a platform that supports both infrastructure as code (IaC) and event-driven architecture. ### When should I avoid airflow? Avoid if you require Windows as the primary execution environment without using WSL2. If your project strictly adheres to MariaDB for database management, Airflow is not recommended because it is neither tested nor supported by the tool. ### When should I avoid kestra? In environments where infrastructure as code (IaC) or event-driven architecture do not align with the project requirements, as these represent core functionalities of Kestra. For teams deeply invested in languages other than Java or looking to avoid it due to existing tech stacks and expertise. If a lightweight solution is required, given that Kestra's robust infrastructure support and event-driven capabilities might introduce unnecessary complexity. ### Is airflow or kestra more popular on GitHub? airflow has more GitHub stars (46,425 vs 27,853). Stars measure visibility, not whether either tool fits your constraints. ### Are airflow and kestra open source? Yes - both are open-source projects on GitHub (airflow: Apache-2.0, kestra: Apache-2.0). ### Where can I find alternatives to airflow or kestra? GraphCanon lists graph-backed alternatives at [airflow alternatives](/tools/apache-airflow/alternatives) and [kestra alternatives](/tools/kestra-io-kestra/alternatives) ([airflow markdown twin](/tools/apache-airflow/alternatives.md), [kestra markdown twin](/tools/kestra-io-kestra/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/apache-airflow-vs-kestra-io-kestra.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, airflow or kestra? airflow: Very active. kestra: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for airflow and kestra? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [airflow trust report](/tools/apache-airflow/trust); [kestra trust report](/tools/kestra-io-kestra/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=apache-airflow`](/api/graphcanon/graph?tool=apache-airflow) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
