ClipHop is live on Product Hunt today

ClipHop — the Bluetooth-LE clipboard sync for Android and Mac — is on Product Hunt today. Here's what we've built, what it does, and where to try it.

ClipHop is on Product Hunt today. If you’ve landed here from PH — thank you for looking. A quick tour of what we’ve built, why, and where to go next.

What ClipHop is#

A clipboard sync app. Install it on your Android phone, install it on your Mac, pair them once, and from that moment on your clipboard hops between the two devices. Copy on one, paste on the other. That’s the whole product.

What makes it different from every other clipboard sync tool we could find:

  • No cloud. Nothing leaves the two devices. There is no server, no account, no remote state.
  • No WiFi required. The transport is Bluetooth LE directly between the two paired devices. Works on planes, on captive-portal coffee-shop WiFi, behind corporate VPNs, on networks you don’t trust.
  • End-to-end encrypted with fingerprint verification. AES-256-GCM, X25519 ECDH per reconnect, Ed25519 long-term identity keys in the Keychain / Keystore. Verify the identity fingerprint at pair time and any time after.
  • Manual send by default. Every clip sits in history until you tap ✈. Your clipboard leaves the device only when you decide.

Why we built it#

The short version: Apple’s Universal Clipboard is Apple-only, LAN-based tools like KDE Connect need a shared WiFi, and cloud clipboards want an account + custody of your clipboard stream. None of those fit the reality of using an Android phone with a Mac while moving between coffee shops, home networks, and planes.

We wanted a small, focused tool that just moves the clipboard, directly, without depending on any third party. So we built one.

The detail lives in a few earlier posts if you want the engineering rationale:

What’s in v0.1.0#

  • Platforms: macOS 13 Ventura or newer (Apple Silicon recommended), Android 10 (API 29) or newer on real hardware.
  • Content: plain text and URLs. Rich text, images, and files are on the roadmap.
  • Pairing: one active pair per device — one phone with one Mac. Multi-pair is on the roadmap, held back as an intentional privacy default for now.
  • Transport: BLE with L2CAP where supported, chunked GATT fallback.
  • History: local on each device, biometric-locked on Android. Android 13+ can mask paste previews in the system keyboard.
  • Cost: free. No subscription, no ads, no upsell tier.

Setup in 60 seconds#

  1. Install on Mac — direct .dmg download.
  2. Install on Android — Play Store link.
  3. Pair — scan a QR on the Mac from the phone, verify the fingerprint, done.

Who built this#

One person, from India. Anshul Garg. Not venture-backed. Not for sale. No growth team, no PMM, no analytics, no retention emails — just the app. If you file a bug, it goes directly to my phone, and I’ll probably reply the same day.

How to help#

If you try it and it works for you:

  • Upvote on Product Hunt today if you found the page.
  • Share it with someone who also lives between an Android phone and a Mac — that’s the audience this tool was actually built for.
  • File bugs at [email protected]. Device model, OS version, what happened. I’ll look at everything.

If it doesn’t work for you — battery drain, pairing fails, a clipboard type we don’t support yet — same email. The product gets better with specific feedback.

What’s next#

After launch, the roadmap in priority order:

  1. Image clipboard support — probably the next major addition. BLE throughput is the bottleneck, not the protocol.
  2. iOS peripheral implementation — same protocol, a different CoreBluetooth implementation. Matches most common “I have an iPhone and an Android, and a Mac” setup.
  3. Multi-pair — two or three paired devices instead of one. With the UX for “which peer receives this clip” figured out, not just “broadcast to everyone.”
  4. Third-party audit of the crypto and BLE stack. Before 1.0. Non-negotiable.
  5. Rich text, files, richer MIME support.

Where to go from here#

  • Try it: download page.
  • Read more: the blog — 10 posts on the engineering, security, threat model, and workflows.
  • FAQ: cliphop.org/faq — six categories, every question we’ve gotten so far.
  • Privacy: cliphop.org/privacy — what we collect (nothing), what stays on your devices, what the apps do.

Thanks for looking. If you came from Product Hunt, we hope the page gave you enough to decide whether to try it. If you came from somewhere else — nice find.
