Show HN: 100.st – Dev utilities I built for format conversions and encoding

[abdelbkk]

I built this because I needed one place for all my dev tasks. Handles JSON/YAML/XML conversions, UUID gen, case transforms, and encoding tools. Built with Next.js/Chakra UI frontend, NGINX on a vps, Cloudflare for dns and cache. All client-side processing for privacy. What tools should I add next?

This is just AI slop. https://100.st/tools/uuid-nil-generator this generator literally just makes an arbitrary number of identical all-zero UUIDs. Then 10 pages of genAI SEO crap after.

Did a human even pass their eyes over this? Why should I trust anything it does?

[abdelbkk]

i ro know what do u mean, uuid nil is basically all ZEROS. the text below each tool just for SEO not for human to read. I assume a developer knows what is a UUID, base64....

I did something similar but with focus on auto-detections and in-browser only: https://wt.tools/tools

Neat.

OC and you just reminded me of Unicode normalization. I've not needed anything in my own work. Might be useful for others.

Another random notion: Validate UUIDs? Like identify its kind, verify its well formed?

[bh213]

It does validate UUID and detects a few versions (I'd have to check which npm package is used for UUID ) but just copy one into input and it should be validated.

The text column is very thin on pages like the IPv6 address generator. The spacing between the lines also seems too high (reminds me of school essays where for some reason you always had to put tons of space between lines). Maybe consider decreasing the space a little bit for readability.

> for some reason

It's so you/the teacher have room to leave comments/corrections.

i also have my own personal toolset when i need https://tools.woz.lt/

cmd+k is the key

[fadeddata]

Looks like a fork of: https://github.com/CorentinTh/it-tools

What makes yours better?

[putna]

it is, it has a link to repo you mentioned. I would say that having your own instance of these tools, gives some confidence when using tools like Passphrase Generator or bcrypt

[ThinkBeat]

That is impressive. I love it.

I wish it came as an offline application.

thats more beautiful and sick modern UI

[dadro]

Looks great. Image/file > Base64 and the inverse could be a useful addition.

[mqus]

even just text > base64 would also be great

[abdelbkk]

thanks i ll add this too

Looks like https://gchq.github.io/CyberChef/ except that you can use CyberChef offline. Why reinvent the wheel all the time?

[jasonlotito]

> Why reinvent the wheel all the time?

Because since the invention of the wheel, there have been a LOT of changes and inventions that have dramatically improved the wheel.

[omneity]

Well it can be a good learning experience for OP, that's reason enough. By the way, I use CyberChef occasionally and I love it, strongly recommended!

[bee_rider]

You have a typo I think, “generatw IPv6.”

thanks
