YAML
YAML ("YAML Ain't Markup Language") is a human-readable data serialization language designed for representing structured data and exchanging it between systems and programming languages.
It uses indentation-based syntax with minimal structural characters, represents data using three core primitives such as mappings, sequences, and scalars, and includes features such as anchors and aliases for referencing data, along with a simple typing system for numbers, strings, and booleans.
YAML is widely used for configuration files, infrastructure definitions, and data exchange in tools and environments such as 
Kubernetes, 
Docker Compose, and CI/CD pipelines, where its readable format simplifies managing complex hierarchical data structures.
According to our data, YAML ranks 16th among the standards we track.
It is detected on 3.5% of all websites.
It appears on 7.4% of all websites in Australia, 7.2% in Canada, and 7.1% in the United States.
