PREVU - Preview social link cards instantly before deployment

While building web apps, I often needed to check how my links would appear when shared on platforms like Twitter, LinkedIn, or Discord. The problem is that most preview tools only work after deployment. So even a small change to an Open Graph image meant redeploying the app, waiting for builds, and checking multiple preview tools again. It slowed down development a lot. So I built Prevu — a lightweight tool that lets you inspect metadata and preview social link cards instantly, even from localhost. Now I can verify link previews before deploying and avoid that repetitive cycle. Would love to hear your feedback!
