[argo-workflows](https://argo-workflows.readthedocs.io/) reports 17k GitHub stars, 3.6k forks, and 1.3k open issues, last pushed Jul 31, 2026. [lws](https://lws.sigs.k8s.io) has 794 stars, 179 forks, and 59 open issues, last pushed Aug 24, 2026. Figures are from public GitHub metadata via [argo-workflows's repository](https://github.com/argoproj/argo-workflows) and [lws's repository](https://github.com/kubernetes-sigs/lws). | | [argo-workflows](/tools/argoproj-argo-workflows.md) | [lws](/tools/kubernetes-sigs-lws.md) | | --- | --- | --- | | Tagline | Workflow Engine for Kubernetes | An API for deploying a group of pods as a unit of replication | | Stars | 16,867 | 794 | | Forks | 3,599 | 179 | | Open issues | 1,321 | 59 | | Language | Go | Go | | Adopt for | Argo Workflows, an open-source workflow engine for Kubernetes implemented as a CRD, is popular due to its lightweight design, scalability, and extensive artifact support. | lws, or LeaderWorkerSet, is an API designed for deploying groups of pods together in Go, aimed at improving orchestration and scale management for better performance. | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | Apache-2.0 | | Categories | Developer Tools, Model Training | Inference & Serving | ## Trust and health _Sourced signals - not a safety guarantee.

See the comparison table for live GitHub stats and shared categories. ### When should I choose argo-workflows over lws? Choose argo-workflows over lws when Tags unique to argo-workflows: cloud-native, machine-learning, mlops, pipelines; Also covers Developer Tools, Model Training; When orchestrating container-native workflows for tasks like machine learning or data processing on Kubernetes. ### When should I choose lws over argo-workflows? Choose lws over argo-workflows when Tags unique to lws: llm-inference, sig-apps; Also covers Inference & Serving; - When you are working with applications that require a high degree of control over pod deployment and replication as part of a microservices architecture. ### When should I avoid argo-workflows? In non-Kubernetes environments due to its tight integration with Kubernetes CRDs and native features For legacy system migrations that require significant VM and server-based overheads, as Argo Workflows is container-centric without such layers ### When should I avoid lws? - Avoid using lws if your project does not benefit from treating pods as units, such as in simpler setups without complex orchestration or scale needs - If you operate primarily within languages other than Go, look for alternatives better suited to those environments because lws is built specifically for applications in Go ### Is argo-workflows or lws more popular on GitHub? argo-workflows has more GitHub stars (16,867 vs 794). Stars measure visibility, not whether either tool fits your constraints. ### Are argo-workflows and lws open source? Yes - both are open-source projects on GitHub (argo-workflows: Apache-2.0, lws: Apache-2.0). ### Where can I find alternatives to argo-workflows or lws? GraphCanon lists graph-backed alternatives at [argo-workflows alternatives](/tools/argoproj-argo-workflows/alternatives) and [lws alternatives](/tools/kubernetes-sigs-lws/alternatives) ([argo-workflows markdown twin](/tools/argoproj-argo-workflows/alternatives.md), [lws markdown twin](/tools/kubernetes-sigs-lws/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/argoproj-argo-workflows-vs-kubernetes-sigs-lws.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, argo-workflows or lws? argo-workflows: Very active. lws: 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 argo-workflows and lws? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [argo-workflows trust report](/tools/argoproj-argo-workflows/trust); [lws trust report](/tools/kubernetes-sigs-lws/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=argoproj-argo-workflows`](/api/graphcanon/graph?tool=argoproj-argo-workflows) - 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/_
