The 2026 winners have been announced. The 2027 round is open now.

About the APL Forge

A proof of concept. A weekend or two of work. A £2,500 prize.

Build with APL. Build for APL.

The APL Forge is an annual competition open to individuals, teams, and companies. The brief is simple: build something useful with – or for – APL, and submit it. Winners receive £2,500, an expenses-paid trip to present their work at a Dyalog user meeting, and a year’s commercial licence.

You don’t need to be an APL expert to enter. A previous winner had been writing APL for less than a year.

One Competition - Two Categories

01 / 02

– in APL
The APL category

For submissions written primarily in APL:

  • Libraries — tools that solve a problem or add capability, even in a niche area. They don’t need commercial potential; expanding what APL can do is enough.
  • Applications and tools — solutions to problems people care about, at any level of polish. A working proof of concept is a valid entry.
  • Modules — plug-ins or add-ons that extend existing APL libraries or applications.

02 / 02

– for APL

The non-APL category

For submissions that improve or promote the APL experience but aren’t written primarily in APL:

  • Tools or plugins that connect APL to other platforms, languages, or services
  • Websites that organise or surface APL-related information
  • Media — books, video series, podcasts, tutorials

What are the prizes?

  • £2,500
  • An expenses-paid trip to present your work at a Dyalog user meeting
  • A Dyalog commercial licence, valid for one year
  • Support from the Dyalog team to help develop your submission further, if you’d like it
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.
