OpenIM Protoc Tool

Introduction

OpenIM is passionate about ensuring that its suite of tools is custom-tailored to cater to the unique needs of its users. That commitment led us to develop and release our custom Protoc tool, version v1.0.0.

Why a Custom Version?

There are several reasons to choose our custom Protoc tool over generic open-source versions:

• Specialized Features: OpenIM's Protoc tool has been enriched with features and plugins that are optimized for the OpenIM ecosystem. This makes it more aligned with the needs of OpenIM users.
• Optimized Performance: Built from the ground up with OpenIM's infrastructure in mind, our tool guarantees faster and more efficient operations.
• Enhanced Compatibility: Our Protoc tool ensures full compatibility with OpenIM's offerings, minimizing potential conflicts and integration challenges.
• Rich Output Support: Unlike generic tools, our custom tool provides a wide array of output options including C++, C#, Java, Kotlin, Objective-C, PHP, Python, Ruby, and more. This allows developers to generate code for their preferred platform with ease.
