No homoglyphs detected!
Homoglyph attacks (also called IDN homograph attacks) exploit visual similarity between characters from different scripts to create deceptive domain names.
Attackers may register domains like "pΠ°ypal.com" (with Cyrillic 'Π°') that look identical to "paypal.com" in browsers, tricking users into visiting malicious sites.
Protection: Always verify URLs carefully, enable punycode display in your browser, use security tools that detect homoglyph domains, and implement URL validation in your applications.
How to use the Homoglyph Detector
To get started with Homoglyph Detector, enter or paste your source data in the input area. All processing happens client-side using modern browser APIs, so your data never reaches a server. Results appear instantly.
Why use the Homoglyph Detector
Instead of opening a code editor or installing a CLI tool, use Homoglyph Detector right in your browser. It handles the task locally, giving you fast, private results without context switching.
When to use Homoglyph Detector
Reach for Homoglyph Detector during code review when you want to verify that a snippet is well-formed, or when you are working on a remote machine and do not have your usual dev environment set up. It also helps when you want to share a clean, readable version of some data with a colleague who does not have the same toolchain installed.
Key features of Homoglyph Detector
Homoglyph Detector offers real-time validation so you catch syntax errors as you paste, multiple output modes (pretty-print, minified, highlighted) to suit different stages of your workflow, and zero configuration β open the page and start working. There are no login prompts, rate limits, or hidden charges.
Common use cases for Homoglyph Detector
Homoglyph Detector is frequently used for: converting log output from a compressed or encoded format into something human-readable during incident post-mortems; preparing cleanly formatted code samples for technical documentation or Stack Overflow answers; and quickly checking whether a third-party library returned data in the expected shape before writing assertions in unit tests.
