Achernar is a European indie development studio based in the Capital Region of Denmark. 🇩🇰


We aim to develop high-quality video games and software alike, and we believe that all technologies should be for humanity as a whole. We therefore publish all relevant source code for our products.

The goal of Achernar is to promote modern and robust software for everyone. In other words, our vision is to develop a human and clean industry and community for technology.


We believe in a society free of patents, and as such we release our scientific software in open-source form. For our games, we try to keep the base engine as open as possible whilst still keeping in mind that they yield our main income.

Currently, our roadmap is as follows:



This roadmap is, however, also subject to change, altough we do strive to live up to it.

As Achernar is currently registered as a PMV (lesser sole proprietorship), Gabriel Bjørnager Jensen is currently our only member.

Achernar was incorporated on the first july of 2024 by current sole proprietor Gabriel Bjørnager Jensen.


Our first domain – achernar.dk – was already registered in the winter of 2021, at that time being used for hosting on-line source code repositories. This was, however, quickly outsourced to mandelbrot.dk after I had managed to secure that domain.


achernar.dk was then, in the mean time, used for hosting a few look-up references. This mostly served as my own notes for school – mainly mathematics, physics, and chemistry – but quickly grew unorganised and unmaintained, although I did have plans to expand the encyclopedia.


The idea of a company had started in the spring of 2020. At that time it would've been named after the binary system Sheliak (Bayer: β Lyræ). But it was this idea that evolved into “Achernar.”


Shortly after being incorporated, we registered the domain achernar.io. At that time, we also set up mail services using our domain.
