This is very good. One thing though Telegram (at least the linux version) does not support transparency and makes the transparency red. However, Metacheck shows it as transparent. Having all this on one page is a massive time saver.
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
