Announcing Gutenberg, a static site engine

Why would we possibly want another static site engine? I already hear some say. That's a very valid question!

I currently have 6 static sites live:

  • (link now dead)
  • (link now dead)
  • (link now dead; redirecting to
  • (link now dead)
  • (link now dead)

Those are all using Hugo, except the blog you're reading that moved to Gutenberg a couple of days ago.

Hugo in itself is pretty great: I switched from Pelican for the speed and the stand-alone binary and stayed for the instant live reload. The huge pain point for me with Hugo is the Go template engine: I find it so bad that it turns a great experience into a, well, sad experience.

When I first looked at Rust a couple of years ago, I thought that a static site engine could be a nice first program to write to learn the language. Sadly, I didn't find a template engine I liked at the time which prompted me to write my own, Tera.

Now that Tera is getting more mature and my frustration with Go templates grows, I started working again on the static site engine a few weeks ago and it got to a point where it's usable.

It's called Gutenberg and is now available in a 0.0.2 version on and Github. It seems AppVeyor is running into some issue with curl so I haven't been able to test it on Windows yet but it should work on Linux and OSX. Binaries are built using the very nice trust project.

The features🔗

Gutenberg is opinionated (only TOML for configuration, only Tera for templates, only CommonMark for content) but is flexible enough to let you build all kinds of sites, from landing pages to knowledge bases, not only blogs.

Features in no particular order are:

  • CommonMark for content
  • Categories and Tags automatic page creation (easy to disable)
  • Automatic RSS feed (easy to disable)
  • Built-in server with fast live reload (a bit buggy currently)
  • Supports having assets next to the content: no need to put everything in a static folder
  • Explicit sections that can have their own page and have access to potential subsections: this allows making pages like which are a big table of contents over several sections
  • Good template engine: I'm a bit biased there
  • Simple to use: no surprises, everything is explicit except from the default templates used

More information is available on the README and better documentation will come once the tool is in a more stable shape.

What's next🔗

As the 0.0.2 version number indicates, Gutenberg is still a work-in-progress. Despite that, it fills almost all my static engine needs. There are a few things that will need to be done before being ready for a 0.1 though:

  • Find and fix bugs, add tests and benchmarks
  • Make it faster: parallelize if possible
  • Pagination: still debating the best way to set up that up in a Github issue
  • Add an equivalent to Hugo shortcodes: they make it easy to embed some HTML in your markdown without repeating HTML all the time, e.g. a youtube video could be added to a page like so {{ youtube(id=87238) }} and the renderer will insert whatever template we defined for the youtube shortcode.

And for after the 0.1 release:

  • Built-in Jupyter renderer would be nice
  • Proper documentation site

The current blocker to parallelization is that syntect, the great library I'm using for syntax highlighting is not thread-safe. There is an issue open but I haven't had the time or energy to look/fix that yet. It should be fairly straightforward to add Rayon once it's fixed, if the benchmarks show a significant difference.

How does it look in practice🔗

You can have a look at the source of this site.

This site is very simple: a blog and a couple of other pages but it should give some ideas.


Obviously, any feedback is welcome! While the general design and current features are unlikely to change, I'd be happy to cover more use-cases if possible.
