This may be a "marketing" issue. I know a little html and css, but I am not a serious programmer. I looked at your thing and I have no clue what it does.
It might help to have a better explanation of what it does and maybe move your examples link higher up the page. This is your current blurb at the top of the page:
webhook is a lightweight configurable tool written in Go, that allows you to easily create HTTP endpoints (hooks) on your server, which you can use to execute configured commands
That means nothing to me. It should tell me how it enhances functionality of my site. "Execute configured comands" just means "and then it does the thing you told it tobdo." Yeah it better do that much. But what kinds of things can I tell it to do?
So, for examples I know:
Hyperlinks are code snippets that tell the browser to go to a particular page.
CSS is code that makes your page more lightweight by reducing how often you have to repeat instructions. You can have a master file that applies to all items in a particular class that only needs to be called once. This makes pages load faster and reduces coding bloat. It is also easier to maintain the site since you can change code across the entire site by editing one file instead of every individual page.
What the hell do hooks do? I don't know that and I have no reason to research it in order to determine if your tool has any relevance to my life. So I am just going to close the browser tab and move on. I have a busy life and you have not given me any reason to care about this tool.
That isn't intended to be mean. I got told for years my sites were too niche and no one cared. I have wrestled with this issue personally and I am sympathetic.
Best of luck.
