nglevel

Nglevel is a term occasionally used in software development to label the maturity or readiness of a feature, component, or change within a project. It is not a formal standard or widely recognized specification, and its exact meaning varies by organization. In practice, nglevel functions as a lightweight piece of metadata that can accompany a version number or feature flag to indicate whether something is experimental, in development, in beta, or stable.

Usage and scope

In build pipelines, deployment scripts, or configuration files, nglevel may determine whether a particular code path is compiled, whether a feature is surfaced to users, or whether a change is included in a release. It can appear in YAML, JSON, or as a code comment, depending on the project’s conventions. Because nglevel is not standardized, teams typically document its semantics in repository guidelines or release policies to avoid ambiguity.

Origin and context

The term tends to appear in scattered project documentation and internal tooling rather than in any formal specification. As such, nglevel should be understood as an internal convention rather than a universal concept. It is sometimes used alongside or in place of related mechanisms such as feature flags, environment gating, and semantic versioning, but it is not a replacement for those established practices.
