runnem 0.1.3

A service manager for managing multiple services in a project

Runnem

Light-weight service manager for local project development. Makes switching between projects a breeze.

Why Runnem?

• One command to rule them all – start, stop and inspect every service in your project without memorising half-a-dozen shell scripts.
• Native speed & tooling – runs processes directly (no mandatory Docker), leveraging battle-tested GNU screen under the hood.
• Port-safe project switching – makes it easy to switch between projects while avoiding port clashes.

Installation

pip install runnem   # Python ≥ 3.8 on Linux, macOS or WSL-enabled Windows

Quick start

# 1 · Create a config for the current directory
runnem init myproject            # omit the name to use the folder name

# 2 · Edit runnem.yaml and add your services
$EDITOR runnem.yaml

# 3 · Launch everything
runnem up                        # starts all services in the right order

# 4 · Check what’s running
runnem list                      # or: runnem ls

# 5 · Stop when you’re done
runnem down                      # stops every service cleanly

Tip: Need only one service? Pass its name to up or down, e.g. runnem up api.

Configuration example (runnem.yaml)

project_name: myproject  # required

services:
  database:
    command: cd database && docker-compose up
    url: postgresql://localhost:5432

  api:
    command: cd api && poetry run uvicorn main:app --reload --port 8000
    url: http://localhost:8000/health
    depends_on: [database]

  frontend:
    command: cd frontend && npm run dev
    url: http://localhost:3000
    depends_on: [api]

Key	Required	Description
command	✅	Shell command executed inside its own screen session.
url		Health-check endpoint and source of the port number; Runnem waits for it to respond before starting dependants.
depends_on		List of service names that must be running first.

Ports are inferred from the url – specify one if you want automatic conflict resolution.

Everyday commands

Task	Command
Start all services	runnem up
Start one service	runnem up <service>
Stop all services	runnem down
Stop one service	runnem down <service>
View live logs	runnem log <service>
List status	runnem list (or ls)
Free a busy port	runnem kill <port>

Multiple projects

Runnem looks for the nearest runnem.yaml when you run a command.
If services from another project are still running you’ll see a warning and can stop them with:

runnem down     # executed from *any* project directory
