Fake US addresses that fail real validation (and a few other tiny browser tools)

I keep a few one-page tools in the browser for work that is too small for a full app, and too annoying to fake by hand.

This is not a directory dump. Below is how I actually use them while shipping forms, docs, and media.

The problem with "real looking" test addresses

Checkout and KYC forms want a street, city, state, and ZIP that look valid. If you paste a real address from Google Maps, you can accidentally trigger a live ship, a real card AVS check, or a real identity vendor.

What I want in UI tests is the opposite:

field lengths look familiar (so layout and masks do not break)
ZIP / state combinations look like the US format
checksums and real-world validation fail on purpose

USA Dizhi generates fictional United States address-format samples for that job. Use it for format learning and QA. Do not use the output for payments, shipping, or identity verification.

A typical flow:

Open the generator.
Copy a sample into your form fixture.
Assert the UI accepts the shape (required fields, ZIP length, state dropdown).
Keep a separate integration test that talks to the real validator with a sandbox account, not these samples.

If your test suite currently uses 123 Main St, Springfield copied from a coworker, replace it. That string is too famous, and some vendors treat it as a known dummy.

Morse in the browser when a ticket dumps `... --- ...`

Every few months a log, CTF write-up, or old radio-adjacent feature dumps Morse as ASCII dots and dashes. I do not want to paste that into a random "decoder" that uploads the string.

MorseClue runs in the browser: English to Morse, Morse back to text, plus decode from audio or an image. Practice stays local.

Useful when:

you are checking a beep / dash renderer
a designer sent a screenshot of a code chart
you want a round-trip: text → Morse → text before you ship a toy feature

Passport-sized photos without installing an editor

Government photo rules are picky (size, head position, background). For a visa or passport upload I use PhotoGov instead of fighting crop handles in a generic editor. It targets 49 document formats across 17 countries.

Watermarks and noise, only on files you own

Clearframe is an inpainting watermark remover for images and video. Only run it on content you own or have permission to edit.

NoiseWipe cleans room tone, hum, and clicks. You get a preview first; full download is paid if you want the whole file. I use the preview to decide whether a podcast take is salvageable.
