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

33•abdelbkk•3d ago

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?

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

D4ckard•17h ago

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.

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

omneity•16h ago

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!

> 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.

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

cmd+k is the key

fadeddata•15h ago

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

What makes yours better?

putna•14h ago

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•9h ago

That is impressive. I love it.

I wish it came as an offline application.

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

mqus•13h ago

even just text > base64 would also be great

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

specialist•13h ago

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•2h ago

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.

rjh29•13h ago

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?
