The Deno KV Hackathon

Announcing the Deno KV Hackathon

UPDATE 2023/06/16: The hackathon is over and winners have been determined. Thanks everyone who participated!

As we continue to improve Deno KV, a zero-config, globally distributed key-value store built right into Deno, we’ve been excited to see a wide range of novel use cases. To further encourage building on Deno KV, we’d love to highlight these projects so we’re inviting everyone to participate in the Deno KV Hackathon.

You can build anything — an API, an edge function, a web app, etc. — so long as it uses Deno KV, is open source, and deployed on Deno Deploy.

The hackathon starts now and the deadline for submissions is Thursday, June 15th, 2023 at 12pm Pacific Time. Winners will be announced on Friday.


First off, we here at Deno want to give a huge shout out to everyone who participated, engaged in our Discord and YouTube, and helped make this an awesome, fun hackathon!

There were 29 submissions! Which is impressive given that you all only had 3.5 days to build something. (And next time, we’ll do a longer one that’ll include a weekend.)

Here are the winners for each category.

Most Fun

Kicking off the first winner of the hackathon is for the category, Most Fun. We were thrilled to see so many fun games come out of the hackathon.

The winning project for this category is KV chopper, a chopper game with Deno KV as the leaderboard, created by Pranev. Congratulations!

Most Technically Impressive

There were so many projects that were technically impressive that we couldn’t decide on a single one (it was a four-way tie 😬). Here are all of the winners for this category, in no particular order:

Ryan’s Favorite

The winning project for Ryan’s Favorite is Reddino, a reddit-like clone, from Blocksnmore and Lukas. Was this a fun project to take on for a hackathon or a well-timed launch to attract reddit’s users during their blackout? 🤔

Fan Favorite

We received 63 votes from the community for which project deserves to win Fan Favorite. The winning project for Fan Favorite is Crux X from the denosaurs Elias Sjögreen and Dean Srebnik. They re-wrote the registry with Fresh and Deno KV, as well as a dose of love and stress.

Runners up in this category include Storybro and Reddino.

And finally…

Overall Best

There were so many awesome projects that it was tough to select a single one. The winning project for Overall Best is Reddino! Congratulations to the Reddino team again!

Since Reddino already won Ryan’s Favorite, we want to give other teams a chance to win some prizes. So the runner up is Stone Bone Cone, a rock-paper-scissors battle royale game from the Abe Train. Great work!
