Binary Releases

For Windows, Mac OS(10.12+) or Linux, you can download a binary release here.

Docker

Official multi-architecture images live on Docker Hub, GHCR, and Quay. Pull the tag you need and run the CLI directly:

docker run --rm ghcr.io/beeyev/telegram-owl:latest --help

Need the binary inside your own image? Copy it from the published image via a multistage Dockerfile:

COPY --from=beeyev/telegram-owl:latest /usr/bin/telegram-owl /usr/local/bin/telegram-owl

This reuses the official build without compiling from source.
