Social card checker
Pixel-perfect social card mockups before the page is live.

The fact that it works on localhost without needing ngrok is huge. I used to deploy to a Vercel preview branch just to test Twitter cards. This saves so much time.

Thank you for sharing. I bookmarked your tool because this is something I needed a couple of months ago and will probably need in the future. Also gave it a GH star.

This is a very handy tool, would you / are you planning to add iOS or android previews for messages?

OG bugs usually come down to "what did the scraper actually read?" more than "is my title present?" Nice idea.

No tunnels, no ngrok, just paste the localhost URL and it actually works? Mind blown. Our whole team uses this now before any big launch.
