The Journal of Open Source Software

The Journal of Open Source Software (JOSS) is a developer friendly journal for research software packages.

What exactly do you mean by 'journal'

The Journal of Open Source Software (JOSS) is an academic journal (ISSN 2475-9066) with a formal peer review process that is designed to improve the quality of the software submitted. Upon acceptance into JOSS, a CrossRef DOI is minted and we list your paper on the JOSS website.

Don't we have enough journals already?

Perhaps, and in a perfect world we'd rather papers about software weren't necessary but we recognize that for most researchers, papers and not software are the currency of academic research and that citations are required for a good career.

We built this journal because we believe that after you've done the hard work of writing great software, it shouldn't take weeks and months to write a paper about your work.

You said developer friendly, what do you mean?

We have a simple submission workflow and extensive documentation to help you prepare your submission. If your software is already well documented then paper preparation should take no more than an hour.

You can read more about our motivations to build JOSS in our announcement blog post.

Code of Conduct

Although spaces may feel informal at times, we want to remind authors and reviewers (and anyone else) that this is a professional space. As such, the JOSS community adheres to a code of conduct adapted from the Contributor Covenant code of conduct.

Authors and reviewers will be required to confirm they have read our code of conduct, and are expected to adhere to it in all JOSS spaces and associated interactions.

Open Source Initiative

JOSS is a proud affiliate of the Open Source Initiative. As such we are committed to public support for open source software and the role OSI plays therein. You can read more about the OSI's affilate program here.


The Journal of Open Source Software is a NumFOCUS-sponsored project.

Cost and Sustainability Model

The Journal of Open Source Software is an open access journal committed to running at minimal costs, with zero publication fees (article processing charges) or subscription fees.

Under the NumFOCUS nonprofit umbrella, JOSS is now eligible to seek grants for sustaining its future. With an entirely volunteer team, JOSS is seeking to sustain its operations via donations and grants, keeping its low cost of operation and free service for authors.

In the spirit of transparency, below is an outline of our current running costs:

  • Annual Crossref membership: $275 / year
  • JOSS paper DOIs: $1 / accepted paper
  • JOSS website hosting (Heroku): $19 / month

Assuming a publication rate of 200 papers per year this works out at ~$3.50 per paper ((19*12) + 200 + 275) / 200 .
