Lock JavaScript Files to Your Domain for Enhanced Security

What is DomainLockJS?

DomainLockJS offers a free and simple solution for website owners seeking to secure their JavaScript files. By generating a customized snippet based on your domain, this tool ensures that your JavaScript code executes only on your authorized website. If the script is used on an unauthorized domain, it intentionally triggers hard-to-diagnose errors, making theft and unlicensed use more difficult for potential abusers.

While not a full-proof method, DomainLockJS acts as a strong deterrent against casual code theft due to its lightweight design and ease of integration. Users only need to enter their website address and insert the generated snippet into their JavaScript files to benefit from enhanced script security.
