I Built 58 Free Browser Tools With Zero Backend — Here's the Full Stack

Every "free online tool" site I've ever used follows the same playbook: upload your file to their server, wait, download the result — usually after a signup wall, a file-size cap, or a watermark slapped on your output.

No backend server. No file uploads. No accounts. No database. Just static HTML, CSS, JavaScr
