Introducing justdev.tools

Introduction

I built justdev.tools to remove friction from everyday developer work. It is a progressive web app that installs directly from the browser, works offline after the first visit, and keeps every operation on the device. There are no accounts, no backend dependency for core tools, and no reason to paste sensitive data into random third-party utility sites.

Why this exists

Most days, developer work includes small but constant utility tasks: formatting payloads, decoding tokens, resizing images, generating hashes, previewing QR codes, converting text encodings, cleaning CSVs, validating regexes, or generating test data. Jumping between tools breaks focus and creates privacy risk. I wanted one place that opens instantly, works on desktop and mobile, and stays dependable offline.

What you can do

At a high level, justdev.tools includes utilities for:

• Data conversion and transformation
• Encoding and decoding
• Hashing and generation helpers
• Media and text utilities
• Developer workflow shortcuts that are useful enough to keep close at hand

Design goals

The project was built around a few constraints:

• Fast enough to feel instant
• Local-first wherever possible
• Installable and reliable offline
• Useful on both desktop and mobile
• Simple enough that each tool does one job clearly

Why it matters

This project reflects the kind of tooling I like to build: practical, fast, privacy-conscious, and focused on reducing friction rather than adding complexity.
