Copyber – A modern clipboard manager I built because none of them felt right
by•
I’m currently working on Copyber, a clipboard manager designed for people who live in Cmd/Ctrl+C land and bounce between macOS, Windows, and (soon) mobile.
It’s not launched yet but I’ve just put out the promo site.
What I’m building with Copyber:
Cross-platform clipboard manager (AvaloniaUI-powered)
Clean, glassy UI inspired by Apple’s LiquidGlass and Windows Fluent
Local-first with optional sync
Focused on practical UX: history, search, and super fast access
Site is live: https://copyber.com
I’d love early thoughts, especially on the direction, design, and what you think a modern clipboard manager should include.

Using AvaloniaUI for a cross-platform clipboard manager is an ambitious choice. At Mobiwolf, we see a lot of teams struggle to balance 'native-feeling' performance with a unified codebase. You’re aiming for the Apple/Windows aesthetic overlap, which is notoriously hard to get right without looking like a generic port.
My main concern for you is the 'Local-first' sync overhead. Once you have users with thousands of clips, the performance cost of local indexing often becomes the real bottleneck. How are you handling the database architecture to ensure that search remains instantaneous as the history grows? That’s where most clipboard tools end up feeling sluggish.
