All The Hugo Themes

My site does well enough with Hugo and a custom theme, but I wanted to explore the themes repository. So I wrote some Python.

If you followed the Hugo Quickstart then you probably already have your own copy of the themes to use. Otherwise you might want to clone the hugoThemes repo with git.

$ cd mysite/
$ git clone --depth 1 --recursive https://github.com/spf13/hugoThemes.git themes


The idea here is to ask Hugo to build and serve the site once for each theme. For each built theme, ask the browser to load and screenshot the site with that theme.

I chose Python for this task. No special reason. I was just in a Python mood that day.

Splinter provided the browser controlling API. Since I’m using Chrome for this, I installed the Chrome WebDriver. The subprocess standard library module allowed me to control hugo, restarting with a fresh theme once the browser had enough time to grab a screenshot.

Then I had a last minute idea: use the convert utility from ImageMagick to collect all the screenshots into an animated GIF.

You may need to install dependencies. Everything you need should be available for your platform, but I still need to double check that. Here are the steps I followed to get things working with Homebrew on my Mac.

$ brew install python3 imagemagick chromedriver
$ pip3 install splinter

All right - that’s out of the way. Now for some code.

#!/usr/bin/env python3

import os
import os.path
import shutil
import subprocess
import time

from splinter import Browser

def is_theme_dir(folder, item):
    if item[0] == '.':
        return False
    full_path = os.path.join(folder, item)
    if os.path.isfile(full_path):
        return False

    return True

if __name__ == '__main__':
    theme_dir = "themes"
    screenshot_dir = "screenshots"
    url = ""

    # Clean up old screenshots
    for f in os.listdir(screenshot_dir):
        filepath = os.path.join(screenshot_dir, f)
            if os.path.isfile(filepath):
        except Exception as e:
            print(filepath, e)

    listing = [ item for item in os.listdir(theme_dir)
            if is_theme_dir(theme_dir, item) ]
    browser_name = 'chrome'
    browser = Browser(browser_name)
    browser.visit(url) # visit out here, reload down there because browser cache

    for theme in listing:
        command = [ "/usr/local/bin/hugo", "server", "--theme", theme ]
        hugo = subprocess.Popen(command)
        time.sleep(1) # More than enough time for Hugo to build the site.
        time.sleep(2) # Allow browser to get external resources.
        message = "Theme: {}, Status: {}".format(theme, browser.status_code)
        screenshot_name = "{}-{}.".format(browser_name, theme)
        screenshot_file = os.path.join(os.getcwd(), screenshot_dir, screenshot_name)
        print("Screenshot saved as: {}".format(screenshot_file))

    # Make an animated GIF of the whole thing.
    convert_command = [ "/usr/local/bin/convert",
            "-delay",  '50',
            "-loop",    '0',
            "-scale", '50%',
            "hugo-themes.gif" ]

The Result

Aside from a few dozen PNG files? Well, there’s that nifty animation. Animated GIFs give me a headache sometimes, so I will link to the GIF instead.


I noticed a few things with this experiment.


Red Lounge

Themes vary significantly in their expected configuration options. Some want social media links under author. Others wanted them in Params. gravatarHash and GravatarHash are two distinct options. Many have hard-coded assumptions in their layouts: an image file /img/avatar.jpg, for example. Sometimes it’s called /media/me.jpg though.

This is not an issue if you pick a favorite from the themes repository and make your site work with your favorite. It is an issue if you’re looking at your site in every theme. I turned my config.yaml into sort of a mess to make it work with more of the themes.


Although many themes focus on blog content, some have a different purpose. Their authors may have created them with project documentation, portfolios, or company sites in mind. Their structure is more complex or requires metadata beyond a simple blog.

I like this variety. I find that it’s much easier to create sites with different purposes using Hugo than when using Jekyll.

Artists Theme

But it does help understand why sometimes the site renders as an attractive blank space in my preview. Examining the theme README would be a good next step if a particular theme interested me.

Well - reading documentation for the thing you’re using is generally a good idea anyways.



The themes seemed a little confused by my craft section. Some ignored craft projects completely, while others integrated them with posts on the index.html listing. Most at least provided a menu link to the section. And yes, the theme README would likely remove my confusion.

You will probably need to customize your template if you have special content.

What Theme Should I Use?

Maybe you were wondering which theme you could use for your new site. I suggest Hyde-X for blog sites. It has nice defaults, and provides quality documentation for its many configuration options. My site started with Hyde-X as a base before moving in its own direction.


Hyde-X isn’t the only way to start. There are numerous excellent blog-focused themes in the repository.

For non-blog sites? I don’t know, to be honest. None of my content worked well with those. Good luck with your search!

Anyways, the important thing is to have fun.
