## Project history and usage

ehco is a lightweight Go TCP/UDP relay and tunneling tool. Its public history is thin but clear: a small networking CLI for forwarding traffic, debugging connectivity, and deploying simple relay paths.

### Project history

The first public GitHub release was v0.0.1 in June 2019. The project reached v1.0.0 in February 2021, and release notes around v1.0 and v1.1 show it adding monitoring, metrics, hot reload, load-balancing improvements, and prebuilt binaries.

Later releases continued the same practical operations focus, including VLESS and Shadowsocks-related work in 2026 and an updater tied to GitHub releases.

### Adoption history

ehco appears to have niche adoption compared with larger proxy stacks. The input package metadata lists Homebrew as the only package manager, while the upstream releases provide ready-made binaries for major platforms.

### How it is used

The README positions ehco for relaying TCP or UDP traffic between hosts, simple network tunneling, debugging connectivity, lightweight proxy alternatives, and internal infrastructure tooling.

### Why package nerds care

For package maintainers, ehco is a small Go networking binary with straightforward release assets. It is interesting mostly as an example of the long tail of useful relay tools that are too small for broad distro fame but useful enough to package.

### Timeline

- 2019-06-15: v0.0.1 is published.
- 2020-06-23: v0.1.0 is published.
