tonight I just [release](https://github.com/digi-monkey/fly-castle) the very first rough version of fly-castle, it is a very simple desktop app to provide a GUI for your own private backup relay written in Rust. the core relay implementation is forked from [scsibug/nostr-rs-relay](https://github.com/scsibug/nostr-rs-relay.git), I might touch the code there to experiment some ideas later.

Currently, I only build for macOS since that's the only OS on my laptop, but maybe I will find a windows computer to build windows one.

Here is how I would love to use it:

## macOS

1. download the software from [here](https://github.com/digi-monkey/fly-castle/suites/10948132678/artifacts/554018902)

2. unzip it, you will get a file named `fly-castle`

3. create a folder named `my-relay` and put `fly-castle` into the folder

4. Start the relay by running the following command on your terminal:

```sh

cd my-relay

sudo chmod 755 fly-castle

./fly-castle

```

5. Open flycat website, click the private backup menu on the left side of the page. add the ws://localhost:8080 to your relay via the right side of the new page.

6. if you want to stop running your little relay, just close the window of fly-castle, it is that simple.
