Wisp

Wisp sends files straight from one device to another, without the cloud and without an account. It's like AirDrop, but it works across phones, laptops, and desktops — not just Apple devices — whether they're on the same Wi‑Fi or halfway across the world.

▸ Send anything, fast
Photos, videos, documents, folders, and clipboard content — drop them into Wisp and they arrive on the other device. When your devices can reach each other directly (especially on the same Wi‑Fi or LAN), files stream straight between them, so speed is limited only by your network — no third party in the middle. When a direct path isn't possible (strict NATs or firewalls), Wisp routes through a relay server so the transfer still completes, and speed then depends on the relay and the route. Either way the connection is end‑to‑end encrypted, so no relay — and no one else — can read your files. Networking is powered by iroh, which always negotiates the fastest path it can between your devices.

▸ Three ways to pair
• Nearby — devices on the same Wi-Fi find each other automatically.
• Pairing code — share a 6-character code shown on the receiver to pair across networks.
• QR code — scan a code shown on the receiver for fully offline LAN pairing, no internet needed.

▸ Resumable transfers
If the connection drops mid-transfer, send the same files again and Wisp will pick up from where it left off instead of starting over.

▸ Saved devices
Devices you've successfully transferred with show up in a "Recent" list, so you can pick them again without re-scanning or re-typing a code.

▸ Built-in Connection Test
A self-diagnose screen surfaces network, rendezvous, LAN, and permission problems with actionable hints when something doesn't work, so you don't have to guess what went wrong.

▸ Privacy by design
• No accounts. You never sign in. There is no email, phone number, or any other identifier to register.
• No analytics, no advertising, no tracking SDKs.
• Files are sent over an end-to-end encrypted peer-to-peer connection built on iroh (https://www.iroh.computer). Only the sender and receiver can read them.
• The optional rendezvous server only sees ephemeral pairing codes used for the handshake — never your files, file names, or recipient list.
• Full privacy policy: https://vigov5.github.io/wisp/privacy-policy/

▸ Free and open source
Wisp is MIT-licensed. Read the source, audit it, run your own rendezvous server, or contribute on GitHub: https://github.com/vigov5/wisp

▸ Cross-platform
• Builds are available for Android, macOS, Windows, and Linux at https://github.com/vigov5/wisp/releases
• iOS support is planned.

Permissions Wisp asks for, and why:

• Wi-Fi / nearby devices — to discover other Wisp devices on your local network using mDNS. The Android 13+ NEARBY_WIFI_DEVICES permission is declared with the "neverForLocation" flag, so Wisp doesn't derive your location.
• Location (Android 12 and below) — only used as a fallback for the mDNS discovery feature; Wisp never reads, stores, or transmits your location.
• Camera — only when you open the QR-scan screen. No image is ever recorded.
• Foreground service + notifications — to keep a long file transfer running when the app is in the background, with the system-required visible notification.

Wisp is a friendly fork of the original Drift project by Samarth Verma, redirected toward Android polish, QR pairing, self-diagnose tooling, and self-hosted rendezvous infrastructure.
