​
Welcome!

We’re Cloudinary, but open source. Powered by Cloudflare. Openinary is an open source, Cloudflare-native media CDN that lets you upload, transform, and deliver images and videos from the edge. Built for developers, no-code builders, and indie creators who want fast, modern, self-hostable media infrastructure.
Openinary is currently under active development. This documentation evolves with the project.

​
Why Openinary?

Open

MIT-licensed, transparent, easy to contribute to

Fast

Edge-first with Cloudflare Workers and R2

Modular

Easily pluggable in any stack or tool

Focused

Just the essentials: upload, transform, deliver

Key Features

​

​
Project Architecture

Openinary is organized as a monorepo with multiple applications:
The main API that handles uploads, transformations, and media delivery.
// API structure
apps/api/
├── src/
│   ├── index.ts      // Worker entry point
│   └── types.d.ts    // TypeScript definitions
├── wrangler.toml     // Cloudflare configuration
└── package.json

​
