Diode 🔌

Open source API proxy server with an easy-to-use dashboard for configuring middlewares and secrets.

What does Diode do?

Third party APIs make it easy to integrate functionalities across apps. But using them on a purely front-end project is a hassle. Most of the time, the API endpoints require an API key which cannot be exposed on the frontend. Hence, most of us setup a proxy backend server that makes the request to the third party API with the API keys and make the frontend request this proxy server instead. While it might be a trivial solution that shouldn't take a lot of time to implement, it can get very repeatable and tedious over time.

Diode solves this problem by abstracting this proxy server and allowing you to add and configure as many API routes and consume them directly on the frontend without having to worry about exposing any API keys! Since Diode sits in between all the requests going to the third-party server, it also makes it easy to add commonly used middlewares to the API route with just a click!
Fun fact: All of this happens without you having to write a single line of code.
