OpenSLO is an open specification for defining service level objectives (SLOs) in YAML. It uses a common format to describe reliability targets across tools and platforms.

The goal of this project is to provide an open specification for defining SLOs to enable a common, vendor–agnostic approach to tracking and interfacing with SLOs. Platform-specific implementation details are purposefully excluded from the scope of this specification.

OpenSLO is an open specification i.e., it is created and controlled, in an open and fair process, by an association or a standardization body intending to achieve interoperability and interchangeability. An open specification is not controlled by a single company or individual or by a group with discriminatory membership criteria. Additionally, this specification is designed to be extended where needed to meet the needs of the implementation.
