Overview
ShyLink.io is a free link management and secure data-sharing tool that combines URL shortening, encrypted secret sharing, QR code generation, UTM campaign building, and a developer API. The site positions it as a single place to shorten, protect, and track links without requiring payment.
The product supports practical link workflows such as custom aliases, expiry settings, click limits, pause and resume controls, real-time analytics, and high-resolution QR codes. It also includes a separate tool set for QR generation, UTM tagging, and safety checking, plus a browser extension and REST API for programmatic use.
Core features
Secure secret sharing
Create encrypted secret messages that are designed to be viewed a limited number of times, with optional expiry settings and active-state controls.
QR code generator
Generate trackable QR codes for any URL or text, with high-resolution PNG downloads and the option to attach the QR code to a short link for scan tracking.
UTM link builder
Build campaign URLs with UTM parameters for Google Analytics, then shorten the resulting link so it is easier to share in social posts and email.
URL safety checker
Inspect suspicious links with the safety checker tool, which is presented alongside the QR and UTM tools as part of the free toolkit.
Developer API
Access a REST API for programmatic creation and management of short links and secrets, with JSON request and response payloads.
Common use cases
Short links for campaigns
Create a short branded link for a long destination URL, optionally add a custom alias, and set expiry or click limits for time-sensitive campaigns.
Temporary secret sharing
Share a private note, credential, or other sensitive text as an encrypted secret that can expire or stop working after being viewed.
Offline promotion and print materials
Generate a QR code for a website, print it on brochures or business cards, and pair it with a short link if scan tracking or destination updates matter.
Campaign tracking
Tag a marketing URL with UTM parameters, then shorten the resulting link so it is easier to publish while still sending campaign data to analytics tools.
Developer automation
Use the REST API to create, list, pause, delete, or inspect short links and secrets from a custom workflow or internal tool.
