PasteKit
I love the simplicity of this. Formatting JSON or SQL is a boring, daily chore, and most of us just default to whatever online formatter pops up first in search. The "privately" part is the real hook here. I've lost count of how many times I've pasted a customer's database schema into some random website and then immediately wondered where that data was going. A local or offline-capable formatter should be the default, not the exception.
That said, I'd want to know a few things. Does it run entirely in the browser with no network calls? Is it a desktop app? Open source? Those details matter for trust, especially in a post-Snowden world where devs are finally waking up to data hygiene. If it's just a front-end wrapper around a formatting library, that's fine, but I'd like to see the code.
The bigger picture here is the quiet shift toward local-first developer tools. We've got VS Code running on web assembly, databases like SQLite making a comeback, and now formatters that respect your clipboard. It's a small move, but it's part of a healthier ecosystem. I'd probably use this for my daily work, but I'd want to make sure it handles edge cases like nested JSON or weird SQL dialects. Still, for a quick paste and format, it's exactly what the doctor ordered.
