One Binary, Every Package Manager: Shipping a Rust CLI To PyPI, Npm, Homebrew, Winget, and Beyond - Ajit Kumar, Wellmatix

Most dev tools die in obscurity because installation friction kills adoption before the first command is run. This talk provides a battle-tested playbook for solving that problem using evnx—a Rust CLI for validating and secret-scanning `.env "files"—as a real-world case study.

Launched in early 2026, evnx achieved thousands of cross-ecosystem downloads within weeks by treating distribution as a first-class engineering concern. The session breaks down a complete distribution matrix:

Registry Packaging: Using crates.io as a source of truth, Maturin for native Python wheels, and npm wrappers for platform-specific binaries.
OS Package Managers: Automating Homebrew formulas via cargo-dist, plus Scoop and Winget submissions.
Developer Integration: GitHub Actions with SARIF output, pre-commit hooks, and lightweight Docker CI images.
Supply-Chain Security: Leveraging PyPI Trusted Publishing (OIDC), provenance attestations, and cosign for signed containers.

Attendees will receive reusable GitHub Actions workflows and manifest templates from the public evnx repo to ship any Rust CLI across ecosystems without sacrificing security or maintainer sanity.
