The problem

Local development is a mess

Multiple Node servers, scattered ports, different commands for each framework. Your local environment becomes chaotic fast.

You don't know which servers are running

Juggling with unreadable ports (3000, 3001, 5173...)

Starting/stopping projects takes too long

Disk space eaten by node_modules

New projects require too many manual steps

Different commands for each framework

"A macOS menu bar app that detects, manages, and orchestrates all your local Node projects — from development to deployment — without friction."

The Mastro promise

Features

What Mastro does today

Everything you need to take back control of your local development environment.

Centralized server management

Automatic detection of all active Node servers on your machine. Clear display of each running instance with automatic framework identification.

One-click start, stop & restart

Start and stop servers with a single click. Define custom start commands per project. Clean restart without going back to the terminal.

Custom commandsNo terminal needed

Built-in local proxy

Embedded proxy to assign a clean, readable local URL to each project. No more exposed ports. Use simple, stable local domains.
