About YAML LLC

YAML supports your stack; We support YAML

YAML LLC is a company founded to provide professional maintenance and enterprise support for the YAML infrastructure that powers modern technology.

Our Mission

We make sure YAML stays secure and keeps getting better—forever.

YAML is invisible but essential infrastructure. From Kubernetes to Ansible, from CI/CD pipelines to cloud configurations, YAML touches every part of modern technology stacks. But like many critical open source projects, YAML has historically relied on volunteer maintenance.

We're changing that.

What We Do

Professional Maintenance

We provide professional, funded maintenance for critical YAML projects:

  • go-yaml - Powers Kubernetes, Helm, and Kustomize
  • pyyaml - Foundation of Ansible and Python's YAML ecosystem
  • libyaml - Fast C library used by many implementations
  • YAMLScript - Next-generation YAML programming language

Enterprise Support

Through the YES Program, we provide:

  • 48-hour early CVE notifications
  • Professional support from YAML experts
  • Strategic influence over YAML's roadmap
  • Training, audits, and consulting services

Specification Stewardship

We maintain the YAML specification at yaml.org and coordinate with the YAML language development team to evolve the standard.

Our Unique Position

YAML LLC has unmatched authority and expertise:

  • Co-created YAML - Founded by Ingy döt Net, co-creator of YAML
  • Maintain core projects - Direct control of go-yaml, pyyaml, libyaml
  • Own key assets - yaml.org specification, github.com/yaml organization
  • Expert relationships - Close collaboration with YAML ecosystem maintainers

Our Values

Sustainability over short-term gains
We're building a sustainable model for open source infrastructure maintenance, not seeking quick returns.
Security as a fundamental right
Everyone deserves secure, well-maintained infrastructure. We prioritize security in everything we do.
Community and enterprise collaboration
We believe enterprises and open source communities can work together for mutual benefit.
Transparent development
All our code is open source. All security fixes are public. We're making open source sustainable, not privatizing it.
