We're excited to announce Clasp Bridge — the fastest way to share clipboard items, files, and text between your iPhone, iPad, Mac, and Vision Pro.
Forget AirDrop dropouts. Forget copy-pasting into Messages. Forget email-to-self. Just scan a QR code.
The Problem
You're working on your Mac. You find a perfect code snippet on your iPhone. Now what?
- AirDrop? "Waiting for device..." (still waiting)
- Universal Clipboard? Works... sometimes... if iCloud feels like it
- Slack yourself? Opens laptop. Opens Slack. Pastes. Sends. Opens phone. Finds message. Copies. Ugh.
We've all been there. It's 2026 and moving 100 bytes of text between two devices you own still feels like defusing a bomb.
The Solution
Clasp Bridge makes this instant:
- Long-press the thing you want to share (in Clasp)
- Tap "Share via QR Code"
- Scan with the other device
- Paste anywhere
That's it. 2 seconds. No setup, no pairing, no account.
How It Works
The 5-Second UX
Sender (Mac with the snippet):
- Right-click clipboard item → "Share via QR Code"
- QR code appears
- Wait for receiver to scan
Receiver (iPhone that needs it):
- Open Clasp → tap "Receive via QR"
- Scan the QR code
- Tap "Accept"
- Content is in your clipboard — paste in any app
Done.
Why We Built This
Privacy
AirDrop is great, but it exposes your device name to everyone nearby. Messages/Slack/email means your data sits on a server somewhere (even if encrypted).
Bridge is different:
- Zero servers — data stays on your local WiFi
- End-to-end encrypted — ChaCha20-Poly1305 (same as Signal)
- Ephemeral sessions — QR codes expire after 5 minutes, keys are destroyed
- No logs — we literally cannot see what you transfer
If you're sharing passwords, API keys, or sensitive notes, you probably don't want them sitting in Messages search forever.
Simplicity
We love AirDrop. But it has two fatal flaws:
- Discovery is flaky — "Searching..." forever on crowded WiFi
- Can't share clipboard items — only files, photos, URLs
Bridge solves both:
- Discovery is instant — you scan the QR, connection happens immediately
- Shares everything — text, images, files, rich clipboard items
No Bluetooth pairing dance. No "Can you see me?" No "Turn AirDrop on." Just scan.
The Technical Deep-Dive (For Nerds 🤓)
Architecture
Bridge has two modes:
1. Local P2P (Default)
When both devices are on the same WiFi:
- Discovery: Bonjour (
_clasp-bridge._tcpservice) - Transport: Network.framework TLS streams (self-signed certs)
- Speed: ~10 MB/s on WiFi 6
- Requirement: Same network (or Apple's AWDL P2P WiFi)
This is the default and covers 95% of use cases.
2. Relay Mode (Coming in v3.8)
When devices are not on the same network (e.g., iPhone on LTE, Mac on office WiFi):
- Transport: WebSocket over TLS
- Server:
wss://bridge.lorislab.fr(Rust + Cloudflare Workers) - Security: Still E2E encrypted — relay only sees encrypted blobs
- Latency: +200ms vs local
Inspired by Tailscale's DERP relay, but simpler (sessions expire after 5 min).
Security
Every transfer is end-to-end encrypted with ChaCha20-Poly1305:
- Sender generates a random 256-bit symmetric key
- Key is embedded in the QR code (never sent to any server)
- Data is encrypted before leaving the sender
- Receiver decrypts using the key from the QR code
- Session expires after 5 minutes — key is destroyed
Even we can't read your data. The relay server (Phase 3) only sees encrypted bytes flowing through.
Try It Now
Clasp v3.7.0 with Bridge is available today:
Free. No account. No subscription. No bullshit.
Open Source
Bridge is open-source (Apache 2.0):
- Repo: github.com/lorislab/clasp
- Docs: Bridge README
- Issues: Report bugs
We're especially looking for help on:
- Relay server Rust impl (Phase 3)
- Android receiver
- Unit tests
