Questions & Answers

As answered by people managing Responsively and CohesionStack Lab.

What makes your product unique?

CohesionStack Lab's answer:

CohesionStack Lab reads a page's Open Graph and Twitter Card tags as they are right now, not from a platform's cache, and shows side-by-side previews for LinkedIn, Facebook, X, Slack and WhatsApp in one place. When you need more than a preview, Metadata Packer pulls the same data from up to ten URLs at once and hands you a CSV plus a ZIP of each page's images and favicons. It's free and doesn't need an account.

Why should a person choose your product over its competitors?

CohesionStack Lab's answer:

Most preview tools check one URL at a time and stop at a picture of the card. CohesionStack Lab also does batch work: you can audit ten pages in one go and export the metadata and image assets, which is useful before a launch or when you're handing pages off to someone else. A strict mode shows exactly what's on the page, and a relaxed mode fills gaps with standard fallbacks and flags every value it inferred, so you can see both what platforms will show and what's missing.

How would you describe the primary audience of your product?

CohesionStack Lab's answer:

Marketers, founders and developers who want their shared links to look right before a launch, campaign or post, and agencies or consultants who need to audit Open Graph metadata across a batch of client pages without installing anything.

What's the story behind your product?

CohesionStack Lab's answer:

CohesionStack is a principal-led technology consulting practice run by Rahul Sawhney, who spent his career building engineering teams at companies including Amazon, The Knot Worldwide and Citrix. The Lab is where he builds small, practical tools for everyday problems teams run into. Link previews that look fine in one app and broken in another kept coming up, and each platform's own debugger only shows its own card, so he built one place to check them all.

Which are the primary technologies used for building your product?

CohesionStack Lab's answer:

The browser front end calls a small backend: an AWS Lambda running a Java container behind Amazon API Gateway, deployed with AWS CDK. The Lambda fetches and parses each page, and the preview images load in your browser straight from the site's own image host.

Who are some of the biggest customers of your product?

CohesionStack Lab's answer:

All marketers, developers and anyone who publishes pages that get shared. The app has no sign up requirements.
