Private · peer-to-peer

own your machine.

The private, low-latency link between your devices: use a spare computer as a second screen for your Mac, even across networks. It's in active development, peer-to-peer and private by default, and free on your LAN.

what makes it different

True peer-to-peer over QUIC

True peer-to-peer over QUIC

Media flows directly between your devices over QUIC — peer-to-peer by default, a managed relay only when a direct path isn't possible.

Frames decode and render GPU→screen via wgpu. The control panel never touches a video frame.

Private by design

Private by design

Your screen stays between your devices, end-to-end encrypted — no third party sees it, even when a relay forwards the packets.

how it works

three steps, then you are in control

  1. 01

    Sign in

    Authenticate with Google, Microsoft, Apple, Facebook, or a 6-digit email code. No password to create or remember.

  2. 02

    See your devices

    Your registered devices appear with live presence. Green means online and ready — no manual IP hunting.

  3. 03

    Connect, peer-to-peer

    Select a device and connect. Media is designed to flow directly over QUIC, peer-to-peer by default — a managed relay steps in only if no direct path is possible (streaming engine in active development).

file sharing

same P2P core, as a CLI

Need to move a file, not a screen? The same peer-to-peer core ships as a CLI. Generate a 6-char code on one end, share it to the other — no accounts required, no cloud storage.

spegla-cli

# on the receiving machine

spegla collect

↳ prints a 6-char code, e.g. X7K2MQ

# on the sending machine

spegla share X7K2MQ ./dir

↳ send to the collector

private by design

your machine, your data

Spegla connects your devices directly, peer-to-peer over QUIC by default — your screen stays end-to-end encrypted, so no third party sees it, even when a managed relay forwards the packets. Built and maintained by Klura. Auth, device registry, and the file-sharing CLI work today; the streaming engine is in active development.
