Private Composer Registry ยท Now in Beta

The Marketplace for
Premium PHP Packages

Sell your Laravel and PHP packages privately. Buyers install them via Composer using their own subdomain wallet โ€” no API tokens, no friction.

composer.json
// 1. Add your private wallet as a Composer repository

"repositories": [{
"type": "composer",
"url": "https://acme.onsynk.com"
}],

// 2. Require any package in your wallet

$ composer require acme/premium-billing
Downloading acme/premium-billing v2.4.1 ... OK

How it works

Three steps to private distribution

No servers to maintain, no auth tokens to manage. Connect once and ship forever.

Step 01

Connect GitHub App

Install the Onsynk GitHub App on your organization. We'll automatically sync your repos, tags, and branches.

Step 02

Push your Tag

Tag a release in Git. Onsynk automatically captures the SHA, registers the version, and makes it available instantly.

Step 03

Sell & Automate

Buyers get a personal Composer wallet subdomain. Add packages to their wallet, and they install via standard Composer โ€” no tokens, zero friction.


Features

Everything you need to ship privately

Built for senior PHP developers who need a reliable, production-grade distribution channel.

Private Composer Registry

Every wallet is a fully Composer-compatible private registry. No extra tooling required.

Automated License Management

Built-in license checker middleware. Each download is validated against the buyer's active wallet.

Secure GitHub App Integration

Downloads are proxied via the GitHub App JWT โ€” no hardcoded tokens, no exposed credentials.

One-Click Wallet Setup

Create a buyer wallet in seconds from the admin panel. Each wallet gets a unique subdomain ready for Composer.

Real-Time Tag Sync

Every Git tag and branch is synced with its commit SHA on package save. Always get the exact commit requested.

Multi-Org Support

Manage multiple GitHub organizations and installations under one account with their own access controls.
