Peak Publisher

Peak Publisher turns your WordPress site into your own plugin update server. It’s built for agencies, product teams, and developers who want to create and ship their own custom plugins and want full control over distribution, versioning, and updates — without relying on third‑party services.

With a modern, task‑focused admin UI, you can add new plugins and releases via drag & drop, validate packages automatically, and publish or draft releases with one click. Your client plugins point to your Peak Publisher site via a standard Update URI, so WordPress will discover and install updates directly from you.

With this solution, you can have your own self-hosted plugin update server in just 5 minutes, allowing you to centrally manage your plugins and deploy updates with incredible ease.

KEY FEATURES

🚀 Clean admin UI with a guided “Add New Plugin” flow A short and focused user interface guides you through the entire process to deploy your first plugin with amazing ease within minutes.

☝️ Drag & drop a ZIP or simply the whole plugin folder You can drop a ZIP file, but the easiest way is to simply drop the entire raw plugin folder or the folder’s contents. The ZIP file will then be created automatically for you.

✅ Automatic validation: headers, version, Update URI Peak Publisher automatically checks each new release for required headers, proper semantic versioning, consistent update URIs, and more to ensure everything is correct.

🧽🫧 Auto‑cleanup of workspace artifacts (e.g. .git, node_modules) To provide clean packages and reduce package size, Peak Publisher automatically removes development files and operating system artifacts from your uploads using patterns that you can configure. (optional)

🔐 Optional restriction via IP/domain whitelist Packages are stored in a private, server-protected directory with no direct web access. By default, access via the API is still possible from anywhere. Using IP or domain whitelisting, you can restrict access to update metadata and downloads.
