Local-first software for devices and networks you trust.

ArcRelay is developed and maintained by Shenzhen Changning Technology Co., Ltd. We build focused tools for the everyday work that happens between your own devices: moving input and content, capturing what is on screen, and connecting directly across private networks.

We start with the device and network you control. Identity, permissions, data paths, platform differences, and release status should remain visible instead of being hidden behind a convenient interface.

Products share a set of principles, but not necessarily the same release cycle, license, or platform coverage. The README and release notes in each product repository are the source of truth for current support.

• Local first. Prefer local devices, LANs, and reachable private networks when a task does not need a cloud round trip.
• Visible trust. Make device identity, permission scope, data destination, and revocation understandable.
• One clear job. Shared foundations should not force someone to install a full suite for a focused task.
• Honest boundaries. Distinguish implemented capabilities, validation work, and released products without promising unverified dates or platforms.
• Open where it helps. Publish source, protocols, and engineering context where they make the software easier to inspect and improve.

The ArcRelay desktop app and the shared components required to build it are available in this organization. Sniptra documentation and standalone binaries are public, while its source code remains proprietary. Mobile applications, release-signing material, private QA and design records, and proprietary integrations are maintained in private repositories. SubnetDesk currently remains in the maintainer's personal repository; its source and downloads remain available from the links above.
