This is my latest vibecode project to address a personal issue:
I have a desktop, a personal laptop, a company laptop, and two phones.
The process of sharing and syncing files between devices while working bothers me because I have to log in with the same account on one app like Lark, Slack, or Telegram or upload to Drive and download it again. The operations are slow and create a lot of clutter while I just need to transfer the file once. Sometimes it’s even a file that needs to be secure.
So what’s the solution?
I created JustSendIt, utilizing Cloudflare’s CDN cache to temporarily cache chunks of data, and of course, each chunk is split into 5MB blocks and each chunk is encrypted separately.
The encryption key is stored locally and shared privately through a method secured by the user.
Within 24 hours, the temporary file chunks will be deleted by Cloudflare, and they will disappear completely.
The system does not save files, does not store them, and is completely secure with the local key.
I am currently using it quite well for personal use, so I am sharing it here in case anyone else needs it for similar purposes.
The operating mechanism and security issues are clearly listed on the website https://justsendit.today/.
