Tools that answer questions about links.

Every tool here does one job on the spot, in your browser. No signup, no daily cap, and nothing you paste is stored. Built by the team behind Raydar, the link-in-bio platform with per-click analytics.

Tagging links so the numbers survive

Campaign tagging fails quietly. Nothing errors, the link works, and three months later one campaign is spread over four rows in a report because the tags drifted. These build the tags consistently, one link or a whole launch at a time, and then catch the drift after it has happened anyway.

• Build UTM links your analytics can group.
  Assemble tagged URLs with live drift warnings and real platform macro tables.
• Tag a whole campaign in one pass.
  Build every link for a launch at once, from a list of destinations and a list of channels.
• Audit a whole set of campaign links at once.
  Check a set of campaign links for the tagging drift that splits one campaign into several rows.

Working out where a link actually goes

A link tells you very little about what happens after the tap. These three open one up without committing to it: reading the parameters riding on it, following every hop to the end, and working out whether it lands in an app or a browser.

• Decode any link.
  Break any URL into plain English and get a clean, tracker-free version.
• Trace a link's full redirect chain.
  See every hop in a redirect chain and catch dropped UTM tags and click IDs before they cost you attribution.
• Make a link open the app, without breaking it for everyone else.
  See which link form opens the app, and which one dead-ends when the app is not installed.

Making a QR code, or checking one before you scan it

Two opposite jobs. One is about to print something and needs to know how large the code has to be and whether the scans can be counted at all. The other has a code in front of them, on a poster or in an email, and wants to know what it hides before pointing a phone at it.

• Make a QR code that still works once it is printed.
  Generate a print-ready QR code, with the sizing maths and an honest answer on tracking.
• Read a QR code without scanning it.
  Decode a QR code from an image and see what it hides, before you point a phone at it.

Checking a file before you send it anywhere

A photo off a phone carries where it was taken and which device took it, and none of that is visible when you look at the picture. This shows you what is in there and takes it out without recompressing the image.

• See what your photo is telling people, then remove it.
  Strip GPS, device and timestamp data from a photo without recompressing it.

Checking what crawlers see

Both of these read the response a crawler actually receives rather than the page a browser renders after JavaScript runs, which is where most of the surprising answers in technical SEO live.

• Test what your robots.txt actually blocks.
  Test a robots.txt against 12+ named crawlers at once and see exactly why each rule won.
• Check what a page's canonical actually says.
  Check the HTML canonical tag and the HTTP header at once, and catch every mismatch class between them.

Getting someone to actually contact you

A bio button that opens a chat with the first message already typed converts better than one that dumps someone into an empty compose window and leaves them to work out what to say. These build that link, and the card you hand over when the conversation happens in person.

• Build a link that starts the conversation.
  Build WhatsApp, call, text and email links, with a readout of exactly what number gets dialled.
• Build a digital business card you can save or scan.
  Create a full vCard with a scannable QR code. Runs entirely in your browser.
