Git-based, password-protected private Pub server.

mpp is pretty minimal, and requires setup, but gets the job done.

mpp is built using Angel, a powerful, production-ready backend framework in Dart. Consider checking it out if you like mpp.

How it works

mpp is a bare-minimum implementation of the Pub server API. It can be configured to fetch package sources from remote Git URL's, and redirects any other request to

For example, if you set up hello to mirror, then you can include package:hello in your own packages, provided that you set up Pub correctly (either via PUB_HOSTED_URL, or explicit hosted dependencies.)

mpp is password-protected, so third parties and malicious parties have no access to your private Dart code. For this to work, mpp requires Basic authentication.

For example, if you have a user foo with password bar, and mpp is running at localhost:3000, you could run the following:

export PUB_HOSTED_URL=http://foo:bar@localhost:3000

And then commands like pub get and pub upgrade would work, seamlessly.


pub global activate mpp


mpp is not a globally-installed package, so expect to the following generated in the working directory:

  • .dart_tool/mpp_packages
  • repos.json
  • users.json

Running the Server

Starts a server at http://localhost:3000 by default, running as many instances as you have available processor cores:


To see options, i.e. port, etc.:

mpp_server -h

Creating Users

mpp auth -u foo -p bar

Hosting a Package

mpp mirror -n <package_name> -u <git url>


Deployment is very much an open-ended process, and thus won't be covered in great detail here. In general, though, the minimal steps are:

  • Install Dart.
  • Install mpp.
  • Using the mpp command line, create as many user accounts as is necessary.
  • Using the mpp command line, mark repositories to be mirrored.
  • Run mpp_server.

However, you might also consider:

  • Configuring HTTPS
  • Using a reverse proxy
  • Running as a daemon (i.e., using systemd)
