Show HN: Client-side ads-free dev utils (diffs, time conversion, JSON formatter)

utils.foo a fully client side, ads-free developer utils app. Today, it has a timestamp converter, base64/url encoder/decoder, json & diff utils, quick pivoting data.

A lot of these exist, but often buried with ads or unclear data usage. I wanted to build something for myself that is ads-free and easy to use.

My goal is get to top 20 commonly used tools, make them feature-rich and then reduce the page size. Will appreciate feature/tools requests and feedback at https://github.com/midplane/forum.utils.foo/issues.
