history

Project history and usage

wush is a Coder-maintained command-line tool for file transfer and remote shell access over peer-to-peer WireGuard connections. Its README describes it as similar to magic-wormhole but without needing to set up or trust a relay server for authentication, and with WireGuard as the secure transport.

Project history

The project is published at `coder/wush` and is written in Go. Its repository structure includes CLI commands, a browser-facing site, overlay networking code, and SSH-related code, reflecting a tool that grew from simple file transfer into a broader remote-access utility.

wush builds on Tailscale's `tsnet` package and public DERP relays but does not require a Tailscale account. The README explains that each CLI manages an in-memory control server, exchanges WireGuard nodes over UDP or DERP, and authenticates connections with x25519 keys embedded in the auth string.

Adoption history

The public repository has drawn visible interest for a young networking utility, with GitHub showing roughly 1.4k stars. Coder also publishes `wush-action`, a GitHub Action that uses wush to SSH into GitHub Actions runners; its README documents a v1.0.0 release on July 26, 2025 and supported Linux, Windows, and macOS runners.

How it is used

A typical flow starts with `wush serve` on a host, which prints an auth key. A client can then run commands such as `wush cp` to copy files or `wush ssh` to open a shell, paste the auth key, and connect over the WireGuard-backed overlay. The hosted `wush.dev` page also presents the tool as send, receive, and access, with command-line to browser use.

Why package nerds care

wush is significant to package and networking-tool watchers because it combines several fashionable building blocks into a small CLI: WireGuard, NAT traversal, DERP fallback, magic-wormhole-style pairing, and SSH/file-transfer workflows. It is not a full VPN product; it is a transient transport for moving bytes or opening shells with less setup.

Timeline

2024: Public discussion and issues around wush appear in the GitHub repository.
2025-07-26: `coder/wush-action` v1.0.0 is released for debugging GitHub Actions with wush.
2026: `wush.dev` advertises wush v0.4.0 with WireGuard-powered peer-to-peer file transfer and remote access.

Related projects

wush is explicitly compared with magic-wormhole in its README. Internally it relies on Tailscale's tsnet and public DERP relay infrastructure, while exposing familiar user workflows such as copying files and opening SSH sessions.
