You know those tasks that aren’t complex enough to justify a dependency but annoying enough to keep reimplementing?
- Validate an email address (syntax + MX records + disposable check)
- Decode a JWT without installing a library
- Look up DNS records
- Check SSL certificate expiry
- Generate a QR code
- Convert between base64 and text
- Explain a cron expression in plain English

It’s not trying to compete with Postman or anything — it’s more like a swiss army knife for when you need a quick answer and don’t want to install anything.
