Version Pilot offers a decentralized and seamless update solution for WordPress plugin developers who host their plugins outside the official repository. It perfectly mimics the native WordPress update experience without relying on a central server.
This solution consists of two parts:
<ol>
<li>Author-side Plugin (“Version Pilot”): You install this plugin on your own WordPress site. It provides a clean interface to manage all your plugins’ update information. This information is then exposed via a secure REST API endpoint.</li>
<li>Client-side Integration Code: A lightweight PHP snippet that you, the developer, embed in your distributed plugins. This code uses WordPress’s built-in hooks to periodically check your Version Pilot API for updates. When a new version is detected, it integrates seamlessly into the standard WordPress update system, allowing your users to update with a single click from their admin dashboard, just like any official plugin.</li>
</ol>
Key Features: 
* Plugin-Centric Workflow: First, add your plugin’s core information. Then, add multiple versions to that plugin. This is more intuitive and reduces data redundancy. 
* Advanced Version Management: Set minimum client version requirements for updates, ensuring compatibility and preventing problematic downgrades. 
* Intelligent Version Matching: Smart logic to serve the most appropriate update based on client version and requirements. 
* Authentication Support: Built-in support for license verification and access control mechanisms. 
* Dedicated Versions List: A complete history of all releases across all your plugins with advanced filtering options. 
* AJAX-Powered UI: Enable or disable updates directly from the versions list with a single click, no page reload needed. 
* Streamlined Process: The “Add New Version” screen is simplified, automatically linking to its parent plugin and requiring only version-specific details. 
* Modern Codebase: Fully refactored for better performance, security, and adherence to modern WordPress best practices.
