Sometimes the smallest dev chores are the ones that interrupt flow the most.

I often need a few GUIDs while testing an API, preparing seed data, writing examples, or filling in mock payloads. It is not hard to generate one from the console, but doing it repeatedly gets annoying fast.

So I turned that tiny workflow into a browser tool: GUID Generator .

What it does

The tool is intentionally simple:

Generate 1 to 20 GUIDs at once

Switch between uppercase and lowercase

Keep or remove hyphens

Add braces when a format needs them

Copy all generated values in one click

Restore recent generated batches from local history

That covers most of the cases I run into when I need IDs for JSON payloads, SQL rows, config examples, or test fixtures.

Why I made it a separate tool

A GUID generator is not a big feature. But when a tiny task shows up many times a week, it is worth making it frictionless.

I wanted the flow to be: open the page, choose the format, generate, copy, move on. No login.…
