Zedata Block is not just a cosmetic change—it's a fundamental rethinking of how userscript metadata should work. By eliminating redundant syntax and using a position-based approach instead of key-value pairs, we've created a format that's both smaller and faster to parse.
While other userscript managers struggle with bloated metadata blocks, Zedmonkey's Zedata format delivers lightning-fast performance without sacrificing compatibility or features.
Full documentation coming soon as we focus on optimizing Zedmonkey to its maximum potential. Zedmonkey already supports scripts using Zedata Block while maintaining backward compatibility with traditional Metadata Block format (though at the cost of carrying unnecessary overhead).
We believe in open collaboration and continuous improvement. Help us make Zedmonkey even better.
We invite security professionals to audit our code for vulnerabilities. Your expertise helps us build a more secure product for everyone.
