Your own self hosted continuous deployment solution for JAM Stack websites.

It takes GitHub repositories containing GatsbyJS sites and builts them once an POST request to a specific URL has been called.

The build happens inside a Docker container to assure that a stable enviroment is provided. Once the build is finished the static files are saved to a dedicated folder inside of sites-public.

Feel free to contact me on Twitter @alexanderhorl or send me a mail (on my GitHub profile) if you like this project or would want to know more about it.

⚠️ Prerequisites

  • You need to have a running Docker instance on your machine. Currently only Docker on Linux or MacOS is supported.
  • Currently only sites based on GatsbyJS are supported. Feel free to contribute by editing the builder to support other static site generators.

🚀 Quick Start

  1. Download this repo

    git clone
  2. Install packages and build server

    Simply run the install script in the downloaded directory.

    $ bash
  3. Create .env file from example

    Use the .env example file to a create a file called .env in the server directory. This file contains all the necessary enviroment variables like the admin password.

  4. Start the server process

    The server process is a NodeJS server listening to a specific port, default 3000. You can change the port by providing a PORT enviroment variable.

    The server process can be started manually.

    $ node server/dist/index.js

    Or using the PM2 process manager by running the following command in the downloaded directory.

    $ pm2 start


    $ pm2 start --env production


Since this project is currently in development theres no frontend to control your sites yet. Though you can still use it simply by doing requests agains the rest server.

When a new site gets added all parameters get saves to the DB and the sites gets a unique 6 digit alphanumeric string as ID.

A new site gets created by posting a POST request against /site and a build gets triggered with a POST to /build/[id].

REST Endpoints

The most important API endpoints are the following, checkout index.js in the server directory for the rest. The default development port is 3000, the production port is 6469. It can be with a either PORT enviroment variable or in the config file in the server directory.

POST /site

Creates a new site instance and saves it to the database, returns the id of the site. Expects content type x-www-form-urlencoded.

field required description
name true Name of the site, only used for front-end purposes.
source true GitHub link to a repository with the site content.
( e.g. )

If you want to use a private repo as source you have to supply a GitHub OAuth token in the source URL, like this. https://<token> JamStackBox is using this technique to clone private repos. You can read how to create a personal OAuth token here.

POST /build/[id or name]

Triggers a new build for the site with the ID.

GET /sites

Returns a JSON array with all sites in the database.

GET /sites/[id]

Returns all details of a specific site.

DELETE /site/[id]

Deletes the site with given ID.

GET /badge/[id or name]

Returns an svg image with the current state of a site, for example building or success.

success badge

📌 ToDo

  • Use dynamic NodeJS version in Builder using NVM.
  • Remote Deployment
  • Add frontend to control sites and builds.
  • Add support for other static site generators than Gatsby.
  • Implement a message broker.
  • Deploy status badge.
  • Split server and builder into dedicated docker containers.
