Submit your project

Ready to enter? Tell us about your project, then share it as a GitHub link or over SFTP. A working proof of concept is enough, and you keep all rights to your work.

Example submissions

To help inspire you, here are some existing APL applications and tools that could potentially have won if their authors weren’t ineligible due to their association with Dyalog Ltd:

Meddy: A Microsoft Windows GUI Markdown editor
Tube: A subway route planner
dyalog-sqlite3: APL bindings for sqlite3

And here are some non-APL things:

Learning APL: An introductory book for programmers
Py’n’APL: A Dyalog ←→ Python interface
APLgolf: HTML frontend to make code golfing in APL easier and more convenient
raylibAPL: a library made to write cross-platform graphical applications

In addition, we have a list of ideas that you can implement or use for inspiration.

Your submission

Firstly, check your eligibility. Then please complete the form below to submit your entry to the APL Forge. If you have any questions, please contact us at forge@dyalog.com or send us a message.

Project Owner / Contact:

Email Address

If you are not entering as an individual, please enter the names of the other people involved:

A description of the problem you aim to solve, how your submission is supposed to work, and how it solves the problem:

The URL of your entry or its GitHub repository. For a private GitHub repository, please add the following GitHub user (one of the APL Forge judges) as a read-only collaborator so that the relevant repository/branch can be cloned for judging when the deadline is reached: bpbecker

If you are not submitting something that can be reached via a URL, put "SFTP" in this field and see the information beneath the Submit Your Project Entry button.

Select your competition category:

Not using GitHub?

For code/documents that are not in a GitHub account, submissions can be made using SFTP. If you would like to use this submission method, enter “SFTP” in the URL field above and we will email information to the email address provided above. Note that this might take a few working days, so please request this as far in advance of the submission deadline as possible to avoid disappointment.

Notes

Your code can be submitted as a workspace or as a folder (like the ones produced by Link.Export or downloaded from a GitHub repository) or by linking to a GitHub repository or branch.
- If you submit a GitHub repository/branch, we will clone it near to the closing date of the current round. Any work done between submission and that date will count towards your solution; any work done after that date will not count. We suggest that you specify a branch for us to clone, so we get the code that you want to submit rather than what you happen to have available when we clone it.
For code that is not open source: Although the judging committee needs to see the code to judge it, they are working under a non-disclosure agreement and you retain the exclusive rights to your code so that you can commercialise your work.

New to APL? You're welcome here.

All you need to enter is a free Dyalog licence. If you’re just getting started, we have tutorials, samples, and a community help channel (the APL Orchard) where experienced APLers are happy to answer questions. We’re also available directly – drop us a line at forge@dyalog.com and we’ll point you in the right direction.

One of our 2026 winners discovered APL just months before entering. You could too.
