Hey HN,

I’ve been an indie hacker for a while, but I haven’t had much success with my past projects. Recently, I came across Marc Lou’s advice about building free tools just for fun, so I decided to give it a shot.

I built Metacheck, a simple tool that lets you preview how any link will appear on Twitter/X, LinkedIn, Whatsapp, Telegram, and other platforms. No API keys, no setup—just paste a link and see the preview.

Why I built this I often ran into issues where social platforms displayed broken or unexpected link previews. Debugging Open Graph meta tags was annoying, so I made a tool to make it easier.

How it works Fetches metadata from any URL Parses Open Graph & Twitter Card tags Shows real-time previews of how the link will look when shared

Try it out: https://metacheck.appstate.co/

This is very cool!

Would it be possible to add Bluesky link cards? It passes through this domain to extract the link card and can be very hit and miss on how they show up.
