Hi HN,

I’m building Smooth CDN, and this is a small playground for testing asset optimization without setting up an account or integrating an API first.

You can upload frontend assets like images, CSS, JS and PDFs, let Smooth CDN process them, compare the optimized versions and get temporary CDN URLs for testing.

The playground is intentionally temporary — uploaded files and CDN links expire after 7 days. The goal is to make it easy to test the workflow before moving assets into a real project or API integration.

I’m trying to validate whether this kind of “asset optimization playground” is useful for frontend developers, WordPress/CMS-heavy sites, and small teams that don’t want to maintain custom optimization scripts.

I’d especially appreciate feedback on: - whether the workflow is clear, - whether the supported file types make sense, - what would make this useful enough to try in a real project, - whether the positioning feels too broad or too narrow.

Happy to answer questions and take brutal feedback.
