vs concurrently

concurrently is the most popular tool for running multiple commands.

Advantages of muxa

  • Preserves interactivity - Vite shortcuts, Expo QR codes work
  • Better output - Clean terminal UI with mprocs
  • Monorepo native - Built-in workspace support
  • Simpler syntax - Cleaner command structure

When to use concurrently

  • Simple CI pipelines
  • Basic parallel execution
  • Existing scripts using it
  • No interactive features needed

Migration Example

# concurrently
concurrently -n "api,web" \
  "cd packages/api && npm run dev" \
  "cd packages/web && npm run dev"

# muxa
muxa -s api dev api -s web dev web

vs mprocs (direct usage)

mprocs is what powers muxa's terminal UI.

Advantages of muxa

  • No config files - Pure CLI interface
  • Simpler syntax - More intuitive commands
  • Workspace aware - Understands monorepos
  • Auto shell wrapping - Handles complex commands

When to use mprocs directly

  • Need advanced mprocs features
  • Want config file control
  • Complex process dependencies
  • Custom keybindings

Example Comparison

# mprocs.yaml
procs:
  api:
    cmd: cd packages/api && npm run dev
  web:
    cmd: cd packages/web && npm run dev
# muxa (no config needed)
muxa -s api dev -s web dev

vs npm-run-all

npm-run-all runs npm scripts in parallel or series.

Advantages of muxa

  • Any package manager - Not just npm
  • Mixed commands - Not limited to npm scripts
  • Better output - Terminal UI vs interleaved logs
  • Workspace support - Cross-package scripts

When to use npm-run-all

  • Only running npm scripts
  • Need series execution
  • Pattern matching scripts
  • Existing npm-run-all setup

Example Comparison

# npm-run-all
npm-run-all --parallel lint:* test:*

# muxa (explicit but flexible)
muxa -c 'npm run lint:js' \
     -c 'npm run lint:css' \
     -c 'npm run test:unit' \
     -c 'npm run test:e2e'

vs Turbo

Turbo is a build system for monorepos.

Different Use Cases

muxa and Turbo solve different problems:

  • muxa - Process runner for development
  • Turbo - Build system with caching

When to use each

Use muxa for:

  • Development servers
  • Watch modes
  • Mixed commands
  • Simple parallel execution

Use Turbo for:

  • Build pipelines
  • Task caching
  • Complex dependencies
  • CI optimization

They work together

# Use Turbo for builds
turbo build

# Use muxa for development
muxa -s web dev -s api dev

vs Nx

Nx is a build system and monorepo tool.

Different Philosophy

  • muxa - Lightweight process runner
  • Nx - Full monorepo solution

Complementary Tools

# Nx for builds and tests
nx build myapp
nx test myapp

# muxa for development
muxa -s myapp serve -s api serve

vs PM2

PM2 is a production process manager.

Different Purposes

  • muxa - Development tool
  • PM2 - Production deployment

Key Differences

  • muxa focuses on developer experience
  • PM2 handles production concerns
  • muxa has interactive features
  • PM2 has monitoring/clustering

vs Docker Compose

Docker Compose orchestrates containers.

Can Work Together

# Start services with Docker Compose
# Run apps with muxa
muxa -c 'docker-compose up' services \
     -s frontend dev \
     -s backend dev

Different Scopes

  • Docker Compose for containerized services
  • muxa for local development processes

Choosing the Right Tool

Quick Guide: If you need interactive features or work in a monorepo, choose muxa. For simple CI pipelines, concurrently might be enough. For production, consider PM2 or systemd.

Decision Tree

  1. Need interactive features? → muxa
  2. Working in a monorepo? → muxa
  3. Just CI/CD pipelines? → concurrently
  4. Need build caching? → Turbo/Nx
  5. Production deployment? → PM2/systemd
  6. Want config files? → mprocs directly

Summary

muxa fills a specific niche:

  • Better than concurrently for development
  • Simpler than mprocs to use
  • Focused on running, not building
  • Designed for modern monorepos

Choose muxa when you want the best developer experience for running multiple processes during development.
