A closer look at Macsmith
Macsmith is a native macOS app that puts common developer environment tasks in one place: find and stop whatever is using a port, manage Homebrew packages and services, start local databases, check runtimes, SSH keys, hosts file entries, DNS and local certificates. Viewing is free; making changes needs a $5 Pro license.
One window for the local setup
Every Mac developer has a mental list of commands for the same handful of problems: what's sitting on port 3000, is Postgres running, which Node version is the default, where did that SSH key go. Macsmith turns those into a native app. It groups 20 tools by job, including processes and ports, packages and services, runtimes and local VMs, SSH and configuration, DNS and local web, and cloud and storage.
The coverage is broad. Port Manager finds and stops whatever holds a port. There are panels for Homebrew packages and services, local PostgreSQL, MySQL and MongoDB, mise and nvm runtimes, Lima and Colima, SSH keys, the hosts file and shell aliases. On the networking side it handles DNS lookups, Caddy and mkcert certificate trust, and what ngrok and cloudflared are doing. It also lists AWS profiles and rclone remotes and can clear out developer caches.
Free to look, Pro to change
The split is simple. The free version shows the state and details of all 20 tools and lets you search across them, which is often enough to work out what is running and why. Macsmith Pro, a one-time $5 launch price that the site says will rise as more licenses sell, lets you install, update, start and stop from the app. Each change is shown before it runs and verified after. A license covers one developer on up to three Macs with future updates, needs to check in online at least every seven days, and can be refunded within 30 days from your license page.
Native and fairly quiet
The app is built in Swift and SwiftUI, needs macOS 14 or later, and is signed and notarized by Apple. There's no account for free use. The privacy page says the app uses the network for things that need it, like downloads, updates, package information, DNS queries and license activation, and that the website only loads Google Analytics if you allow it.
It suits developers who spend time managing local services and would rather click than remember flags. People happy in the terminal may find the free version useful mainly as a dashboard.
