Twitter Card Validator Alternative
Twitter killed their Card Validator in 2023. MetaShield is the free replacement — and it works for every platform, not just Twitter.
What happened to Twitter's Card Validator?
In 2023, Twitter (now X) removed their official Card Validator tool as part of broader API and feature cuts following the acquisition. The validator let developers preview how their links would appear in tweets and debug meta tag issues. There is no official replacement — the Cards section of the developer portal now redirects to generic docs with no preview functionality.
This left millions of developers and content creators without a way to check their Twitter Cards before sharing. MetaShield fills that gap — and goes much further.

Frequently Asked Questions
Is there any official Twitter Card Validator replacement?
No. Twitter/X has not released a replacement for their Card Validator tool. The official documentation suggests using Tweet Composer to preview cards, but that requires posting a tweet (or scheduling one) to see the preview. MetaShield lets you preview without posting anything.
Does MetaShield check the same tags as Twitter's validator?
Yes — and more. MetaShield checks all twitter:card meta tags (twitter:card, twitter:title, twitter:description, twitter:image, twitter:site, twitter:creator) plus Open Graph tags that Twitter/X uses as fallbacks. You also get analysis for 5 additional platforms.
Is MetaShield free?
Yes. The free tier gives you 10 checks per day — enough for most developers. If you need unlimited checks, there's a Pro plan.
