README

prox

A modern process manager for development with an API-first design.

Features

• Simple by default - Procfile-like experience with minimal configuration
• API-first - Full process control and log access via HTTP
• Interactive TUI - Real-time log viewing with filtering and search
• HTTP/HTTPS proxy - Friendly local hostnames with shared multi-project port support
• Health checks - Optional health monitoring for processes

Installation

Homebrew (macOS)

brew install charliek/tap/prox

Linux (apt)

sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://apt.stridelabs.ai/pubkey.gpg | \
  sudo tee /etc/apt/keyrings/apt-charliek.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/keyrings/apt-charliek.gpg] https://apt.stridelabs.ai noble main' | \
  sudo tee /etc/apt/sources.list.d/apt-charliek.list
sudo apt update
sudo apt install prox

Tested on Pop!_OS 24.04 and Ubuntu 24.04+. Architectures: amd64, arm64. See apt-charliek for the full repo.

Linux (.deb download, no apt repo)

For one-off installs without configuring the apt repo (CI runners, locked-down hosts, etc.):

ARCH=$(dpkg --print-architecture)        # amd64 or arm64
VERSION=0.1.3                            # check https://github.com/charliek/prox/releases for the latest
curl -fLO "https://github.com/charliek/prox/releases/download/v${VERSION}/prox_${VERSION}_${ARCH}.deb"
sudo apt install -y "./prox_${VERSION}_${ARCH}.deb"

The apt install ./...deb form resolves dependencies; plain dpkg -i would skip that step.

Other Methods

# Install via Go
go install github.com/charliek/prox/cmd/prox@latest

# Or build from source
git clone https://github.com/charliek/prox.git
cd prox
make build

Claude Code / agent skills

prox ships a skill that teaches your coding agent to drive the prox CLI (read prox.yaml, start/stop processes, tail logs, reach services through the proxy, inspect requests). Install the CLI (above) first, since the skill drives it.

The general route (skills) installs into Claude Code, GitHub Copilot, OpenCode, and other agents:

npx skills add charliek/prox

For Claude Code, a native plugin is also available (it namespaces the skill as prox:prox):

/plugin marketplace add charliek/prox
/plugin install prox@prox

Quick Start

Create a prox.yaml in your project directory:

processes:
  web: npm run dev
  api: go run ./cmd/server
  worker: python worker.py

Start all processes:

prox up

Start with the interactive TUI:

prox up --tui

Configuration

Simple Form

processes:
  web: npm run dev
  api: go run ./cmd/server

Expanded Form

api:
  port: 5555
  host: 127.0.0.1

env_file: .env

processes:
  web: npm run dev

  api:
    cmd: go run ./cmd/server
    env:
      PORT: "8080"
      DEBUG: "true"
    env_file: .env.api
    healthcheck:
      cmd: curl -f http://localhost:8080/health
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 30s

CLI Commands

prox up [processes...]           # Start processes (foreground)
prox up --tui [processes...]     # Start with interactive TUI
prox stop                        # Stop running instance
prox restart <process>           # Restart a process (re-reads prox.yaml, applies its current config)
prox status                      # Show process status
prox logs [process]              # Show recent logs
prox logs -f [process]           # Stream logs
prox requests                     # Show recent proxy requests
prox proxy routes                 # Show shared proxy route ownership

Proxy

Configure proxy and services to expose local processes through HTTP or HTTPS hostnames. When more than one project uses the same proxy port, prox automatically uses a shared per-user daemon so each project can own distinct hostnames on one port.

proxy:
  enabled: true
  https_port: 443
  domain: local.example.dev

services:
  app: 3000
  api: 8000

With another project using the same https_port, both can participate on 443 as long as the service hostnames differ. Inspect ownership with:

prox proxy routes

HTTP API

By default, the API binds to a dynamic (auto-assigned) localhost port. Discover the address with prox status, or pin a fixed port by setting api.port in prox.yaml (e.g. api.port: 5555).

Endpoint	Method	Description
/status	GET	Supervisor status
/processes	GET	List all processes
/processes/{name}	GET	Get process details
/processes/{name}/start	POST	Start a process
/processes/{name}/stop	POST	Stop a process
/processes/{name}/restart	POST	Restart a process
/logs	GET	Retrieve logs
/logs/stream	GET	Stream logs (SSE)
/shutdown	POST	Shutdown supervisor

Security

Configuration files are executed as code (via shell). Only use configuration from trusted sources, similar to Makefiles or Procfiles.

When binding to non-localhost interfaces, authentication is automatically enabled. A bearer token is generated and stored in ~/.prox/token.

Documentation

Full documentation is available at charliek.github.io/prox.

Local docs live under docs, including the CLI reference, configuration reference, HTTP API reference, and architecture notes.

Development

Prerequisites

This project uses mise to manage tool versions. With mise installed, all dependencies are set up automatically:

mise install

This installs the correct versions of Go and golangci-lint as defined in .mise.toml.

Alternatively, install manually:

• Go 1.24+
• golangci-lint v2 (brew install golangci-lint on macOS, or see install docs)

make build    # Build the binary
make test     # Run tests
make lint     # Run linters
make clean    # Remove build artifacts

Documentation Development

The documentation site uses MkDocs with Material theme.

# Install dependencies
uv sync --group docs

# Local preview (http://127.0.0.1:7070)
uv run mkdocs serve

# Build static site
uv run mkdocs build

Documentation is automatically published to GitHub Pages on push to main.
