Sinch CLI

The Sinch CLI builds, tests and deploys Sinch Functions from your terminal, and manages the Sinch resources those functions use: phone numbers, voice services, SIP trunks, conversation apps.

github.com/sinch/cli is the public home for the CLI: releases, the changelog, the issue tracker and the function templates.

Install

npm install -g @sinch/cli
sinch --help

Requires Node.js 20 or later. @sinch/cli is a small launcher; npm picks the binary for your platform (Linux x64 and arm64, macOS Intel and Apple Silicon, Windows x64) as an optional dependency, so do not install with --omit=optional. Update later with sinch upgrade.

Standalone binaries for each platform are attached to every release, with a SHA256SUMS file. They are not code-signed yet, so macOS and Windows block the first run until you allow it.

Quick start

sinch auth login                      # authenticate once, credentials go to your OS keychain
sinch functions init                  # pick a template, scaffold a project
cd my-function
sinch functions dev                   # run locally, hot reload, optional tunnel for webhooks
sinch functions deploy                # build and deploy to Sinch
sinch functions logs <id> --follow    # stream logs from the deployed function
