dev-utils

A collection of fast, simple developer tools. CLI tools run natively. Tools with Python dependencies (JWT, QR, cron) auto-wrap in Docker — zero host install needed.

cd ~/dev-utils
./install.sh

Web Tools

Open in browser:

• json-forge.html — JSON formatter
• json-forge-pro.html — JSON/CSV/XML converter
• regex-tester.html — Regex tester

Docker Setup

Some tools (jwt-tool, cron-parser, qr-tool) require the dev-utils Docker image. The install script can build it for you, or do it manually:

cd ~/dev-utils
docker build -t dev-utils .

These tools auto-wrap in Docker when called — no environment pollution, no pip installs.

If you use rootless Docker, set DOCKER_HOST in your shell rc:

export DOCKER_HOST=unix:///run/user/$(id -u)/docker.sock
