Open-source alternatives to Goconfig

extensible, high-performance configuration management library, optimized for hierarchical data

Kong is a declarative command line interface framework and parser for Go. It maps flags and positional arguments directly into typed Go structures using struct tags, allowing developers to define terminal interfaces through data models rather than manual parsing logic. The project functions as a configuration mapper that populates Go structures from a combination of command-line arguments, environment variables, and JSON files. It distinguishes itself by providing a dependency injection container to pass external services into command handlers and a plugin architecture for dynamic command reg

Go minimalist typed environment variables library

Hydra is a hierarchical configuration framework and type-safe configuration manager. It is designed to manage complex application settings through composable configuration files and command-line overrides, ensuring that configuration values match expected data types during instantiation. The framework functions as a dynamic object instantiator that creates class instances directly from hierarchical configuration values and nested objects. It also operates as a hyperparameter sweep orchestrator and cluster job launcher, enabling the execution of multiple application runs across parameter range

This project provides a collection of optimized configuration boilerplates and templates for Nginx web servers. Its primary purpose is to provide a standardized foundation for server performance tuning, security hardening, and the deployment of virtual hosts. The suite includes specific directives to mask server identity, protect sensitive system files, and secure communication. It also features predefined templates for managing multiple secure and non-secure website hosts using a modular directory structure. Broadly, the project covers server resource tuning through worker process adjustmen

Library for setting values to structs' fields from env, flags, files or default tag

Parse configuration values into given struct from environment, files, json, bytes, or other input convertible to bytes

Sonic is a high-performance Go JSON serialization library that provides tools for encoding and decoding native data structures. It functions as a JIT-accelerated encoder, a JSON AST parser, a stream processor, and a lazy decoder. The project utilizes just-in-time machine code generation to optimize the encoding of large data schemas and employs a JIT assembler to maximize serialization and deserialization speeds. It features a precompiled schema warmup process to prevent latency spikes during initial execution and leverages SIMD hardware instructions for accelerated parsing. The library cove

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,

High-performance configuration management framework for Go applications with zero-allocation performance, universal format support (JSON, YAML, TOML, HCL, INI, Properties), and an ultra-fast CLI powered by Orpheus.

Vault provides centralized, well-audited privileged access and secret management for mission-critical data whether you deploy systems on-premises, in the cloud, or in a hybrid environment.
