Open-source alternatives to Envh

env is a Go library that reads environment variables and populates the fields of a Go struct according to tag directives. It uses reflection to iterate over struct types and tags at runtime, mapping environment variable names to struct fields and applying parsing behavior defined in struct tags. The library supports required field validation, returning errors when marked fields are missing or empty after parsing. It also provides default value fallback from struct tags when environment variables are not set, environment variable expansion that recursively substitutes references within values,

godotenv is a Go library designed to load, parse, and serialize environment configuration files. It provides tools to extract configuration data from files into maps and inject those key-value pairs directly into the system environment of a Go application process. The project includes a configuration file serializer for exporting environment variable maps back into formatted files and a parser for extracting data without modifying the system environment. It supports injecting variables from strings or files into the process environment using priority-based overloading and overwriting. The li

envconfig is a Go configuration decoder and environment variable mapper that deserializes environment variables into structured Go data types. It provides tools for validating mandatory fields and ensuring application configuration adheres to the external configuration patterns of twelve-factor app compliance. The library features a help generator that creates formatted usage text based on struct definitions to describe expected environment variables. It also includes a validation tool capable of detecting unused environment variables that match a specific prefix but do not correspond to any

Viper is a configuration management library designed to centralize application settings from diverse sources into a unified, type-safe registry. It aggregates data from local files, environment variables, command-line flags, and remote key-value stores, providing a single source of truth for application state. By utilizing a hierarchical key-value registry, the system resolves configuration values based on a prioritized stack of providers, ranging from default values to runtime overrides. The library distinguishes itself through its pluggable provider abstraction and dynamic update capabiliti
