My new Unfurler tool

A long time ago, Twitter used to have a little crappy part of their docs site where you could put in a URL and it would show you what the unfurl would look like before you actually post the URL.

For some reason, they removed that. I have never understood why.

I often want to see what the unfurl of some new website or page I’m working on will look when I share it. Before I share it.

Well, thanks to the lovely people building LLMs for us, I’ve spend less time building it than I have writing this blog post already.

Check it out at unfurler.dev.

Fable, or whatever built it for me, added some pretty cool stuff too. It breaks down all the fields, if it sees them or not. It crawls it with the User-Agent that the service does so you can see if it’s needlessly blocked. It shows you what’s broken and gives you a clipboard thingy you can give to an agent to fix it.

You can find the source at schacon/unfurl and if anything isn’t what you expect, just drop me an issue.
