Just built Zync — a privacy-first tool to instantly share code, links, or notes (no login) (zyncshare.vercel.app)

I wanted a dead-simple way to share text, links, or code without creating accounts or dealing with messy UIs. So I built Zync(https://zyncshare.vercel.app/) — paste, share, done.

Share plain text, links, or code instantly
Replies work without login
Everything auto-expires in minutes or hours
No tracking, no ads, no clutter.

Would love to hear what you think. Is it something you’d actually use?

Even a captcha would work. You wouldn't have to have your users create a one time use password, you can just have a set of 5 random numbers that someone has to type in in order to access the data.

Do you think adding a basic captcha would actually stop these kinds of abuse attacks, or is there a better way? I think it will stop bots but I don't really know about preventing users. I’m still testing ideas like optional PINs, like the other comments said , but I’m not sure which one gives the best balance of security and ease for users. Would love your thoughts!

It will stop the lazy, which is 99% of the battle. If you want some form of security, then either a user generated pin or a captcha will do the trick to keep bots away. If you want to avoid both of those, then a longer url will also work. 12 characters will prevent attacks from getting anything but lucky.

Yeah! I just wanted to build the simplest UX for users and just added a 6-character access key for every Zync, plus basic rate limiting to stop mass scraping. It’s invisible to users but blocks most common abuse. Will keep improving it based on all your feedback — appreciate it a lot.
