Proksi: Automatic SSL, HTTP, and DNS Proxy

About

Proksi is a simple, lightweight, and easy-to-use proxy server that automatically handles SSL, HTTP, and DNS traffic. It is designed to be used as a standalone proxy server or as a component in a larger system. Proksi is written in Rust and uses Pingora as its core networking library.

Features

Of the many features Proksi offers is the ability to load balance to your infrastructure or any IP that supports your host configurations. Other features of Proksi also include:

• Automatic Docker and Docker Swarm service discovery through labels
• Built-in most common middlewares such as OAuth, Rate Limiting, CDN Caching and others
• The ability of running it as a single binary in your system
• Automatic SSL through Let's Encrypt and redirection from HTTP to HTTPS
• Configuration through HCL with support for functions (get environment variables, etc)
• Powerful plugin system for adding new middlewares and other features using WebAssembly (WASM)
• Many others.

Quick start

1. Download the latest release from https://github.com/luizfonseca/proksi/releases
2. Create a configuration file named proksi.hcl
3. Add the following content to the file:

lets_encrypt {
  enabled = true
  email = "my@email.com"
}

paths {
  # Where to save certificates?
  lets_encrypt = "./"
}

# A list of routes Proksi should handle
routes = [
  {
    # You might need to edit your /etc/hosts file here.
    host = "mysite.localhost",

    # Will create a certificate for mysite.localhost
    ssl_certificate =  {
      self_signed_on_failure = true
    }

    # Where to point mysite.localhost to
    upstreams = [{
      ip = "docs.proksi.info"
      port = 443

      headers = {
        add = [{ name = "Host", value = "docs.proksi.info" }]
      }
    }]
  }
]

4. Run Proksi with your configuration:

# Option 1: Specify exact config file path
proksi -c /path/to/your/proksi.hcl
proksi -c /path/to/your/config.yml

# Option 2: Specify directory (looks for proksi.hcl, proksi.yml, proksi.yaml)
proksi -c /path/to/config-directory/

# Option 3: No config (uses minimal defaults with Let's Encrypt disabled)
proksi

Configuration File Handling

Proksi supports flexible configuration file loading:

• Direct file paths: Specify any filename with a supported extension (.hcl, .yml, .yaml)
• Directory paths: Proksi will look for proksi.hcl, proksi.yml, or proksi.yaml in the specified directory
• No configuration: If no -c flag is provided, Proksi uses minimal default settings with Let's Encrypt disabled and emits a warning
