V2Kit: A Lightweight Toolkit for V2Ray Config Manipulation

V2Kit: A Lightweight Toolkit for V2Ray Config Manipulation

Overview

V2Kit is a lightweight and extensible Python toolkit for working with V2Ray proxy configurations and subscriptions. It provides a clean API for common operations such as protocol detection, configuration validation, config relabeling, and subscription encoding/decoding. The project is designed with simplicity, predictability, and composability in mind, making it suitable for automation scripts, proxy pipelines, networking tools, and future extensions around V2Ray ecosystem utilities.
