Secure, private clipboard sync between PC and mobile

I got tired of texting links and code snippets to myself just to open them on another device. Third-party cloud clipboards often leak data, so I built ClipFlow. It’s a secure, cross-platform tool that instantly syncs your clipboard between PC and mobile devices. It runs entirely on your own personal Google Firebase infrastructure, meaning your data never touches any third-party servers. 100% private, zero-knowledge architecture, and absolutely no limits on the number of active devices.

Hey Product Hunt! 👋 I’m Andrii, the creator of ClipFlow. Like many developers and creators, I copy dozens of links, text blocks, and code snippets every day. I got completely sick of sending them to my own personal chat in messengers just to open them on another device. On the other hand, traditional cloud clipboards always raised data privacy concerns for me. I didn't want my clipboard logs sitting on someone else's servers. So, I decided to build a solution. ClipFlow is a secure, cross-platform shared clipboard that gives you 100% control over your data. It connects directly to your own personal Google Firebase infrastructure. No third-party middleware, no data tracking, and no limits on how many devices you can connect. Your data stays truly yours. It takes less than 5 minutes to set up. I’d love to get your feedback on the product, the setup process, or any features you'd like to see next! Thanks for checking it out! 🚀

Building a cross-platform clipboard sync with zero server costs — is it possible?

Hey everyone! I m launching ClipFlow in 11 hours. It's a cross-platform shared clipboard tool built for developers and power users who care about data privacy.
When architecting it, I wanted to solve two big problems: avoid third-party servers touching sensitive clipboard data, and avoid huge infrastructure costs for myself as a solo indie developer.
The solution? ClipFlow creates a secure personal network using the user s own Google Firebase config, completely encrypted client-side with a single shared password. Zero database load on my side, 100% data control on the user's side.
Would love to hear your thoughts on this architecture approach! See you at midnight PT!
