unshorten.app โ€” Link Unshortener & Redirect Chain Checker

unshorten.app helps you reveal where a link really goes. Paste any short or suspicious URL and instantly see the final destination, the full redirect chain, and basic security flags โ€” with an option to clean tracking parameters (UTM, fbclid, gclid, and more).

What it does

  • Unshorten any link to reveal the final URL and final domain
  • Trace redirect chains step-by-step (status codes + Location headers)
  • Highlight suspicious patterns (punycode xn--, mixed scripts, @ tricks, IP hosts, uncommon ports, very long queries, downloadable-looking URLs, long redirect chains)
  • Remove tracking parameters for clean, shareable URLs
  • Built to be fast, lightweight, and privacy-first

Privacy-first by design

unshorten.app does not proxy page content. It follows redirects and returns metadata only (HTTP status codes, redirect locations, and the final URL).
Some websites may block automated checks or require JavaScript, so results may occasionally be incomplete.

Who itโ€™s for

  • Anyone who wants to verify a link before clicking (emails, DMs, ads)
  • Support / ops teams debugging broken links or redirect loops
  • Developers / SEO folks tracing 301/302 behavior
  • Marketers cleaning tracking-heavy URLs before sharing

Pricing

  • Free plan for occasional checks
  • Pro (Early Access) planned: higher limits, shareable result links, optional history, and API access

Nullstack features and specs

    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

    Optionally removes common trackers like utm_*, fbclid, gclid, msclkid, and more.
  • Suspicious Link Flags
    Flags common risk signals: punycode (xn--), mixed scripts, @ in URL, IP/private IP hosts, uncommon ports, long queries, and download-like URLs.
  • Privacy-First Metadata Only
    Does not proxy page content โ€” follows redirects and returns metadata + final URL only.
  • Fast, No Account Required
    Works instantly in the browser with a simple paste-and-check workflow (free plan).

Questions & Answers

As answered by people managing Nullstack and Unshorten.app.

What makes your product unique?

Unshorten.app's answer:

Most unshorteners only reveal the final URL. Unshorten.app also highlights risk signals (punycode/mixed scripts/@ tricks/IP hosts/uncommon ports) and can remove tracking parameters, so you can verify and share links more safely.

Why should a person choose your product over its competitors?

Unshorten.app's answer:

Unlike many โ€œlink previewโ€ tools, Unshorten.app is designed to be privacy-first: it follows redirects and returns metadata without fetching or proxying full page content.

How would you describe the primary audience of your product?

Unshorten.app's answer:

Unshorten.app is primarily for people who need to verify and understand links quickly โ€” everyday users checking suspicious short links (from emails/DMs/ads), plus developers, support, and SEO/marketing teams who need to trace redirect chains, debug broken redirects, and clean tracking-heavy URLs before sharing.

What's the story behind your product?

Unshorten.app's answer:

Unshorten.app started as a simple โ€œpaste a link and see where it really goesโ€ tool. Short links are everywhere โ€” in emails, DMs, and ads โ€” and they hide the real destination behind redirects and tracking. I built Unshorten.app to make link checking instant: reveal the final domain, trace the redirect chain, flag common suspicious patterns, and optionally remove tracking parameters โ€” all in a lightweight, privacy-first interface.
