We're excited to kick off another DEV Weekend Challenge, a short bite-sized challenge planned to fit into your weekend. We know the submission window is tight, so we've set the timing to ensure that no matter where you are in the world, you'll have the majority of your Saturday and Sunday to participate.
We’ll select four overall winners and six prize category winners who utilize a specific technology as part of their challenge submission.
Let’s get to it!
Prize Categories
This challenge introduces something new: six prize categories for participants who incorporate a specific technology into their project. You don't need to use any of these tools to be eligible for our overall winner spots but if you're curious about any of the tech, this is a great excuse to give one a try.
- Best use of Backboard
- Best use of Auth0 for Agents
- Best use of Google Gemini
- Best use of Snowflake
- Best use of GitHub Copilot
- Best use of Solana
Pro Tip: since prize category winners are drawn from a smaller pool of submissions, your odds of taking home a prize are meaningfully higher.
Note: You may use multiple technologies in a single submission to qualify for multiple categories, but participants are limited to one win per challenge.
Judging Criteria
All submissions will be judged on the following:
- Relevance to Theme: Does the project clearly connect to the challenge theme?
- Creativity: Is the concept original or is it an interesting take on a familiar problem?
- Technical Execution: Is the project functional, well-built, and easy to use?
- Writing Quality: Is the submission post clearly written and engaging?
- Use of Prize Category Technology (optional): If pursuing a prize category, does the submission meaningfully incorporate the chosen technology?
Prizes
Ten winners will each take home:
- $100 USD
- DEV++ Membership
- Exclusive DEV badge
All participants with a valid submission will receive a completion badge.

Cool!
Question: for Google Gemini category, does one have to use Gemini API or any use of Gemini (e.g. Gemini CLI) would do?
We'll put priority on teams that use and implement the Google Gemini APIs. It's encouraged to use Gemini CLI, Antigravity, or AI Studio to help you build your app, but we're awarding the prize for the best implementation/use of the api itself.
Thanks! That answers it.
Use promo code DEVAPRIL for dev credits at backboard.io/hackathons and you can bring your Gemini API key along with ya!
Nice!
Great question I guess they'll need API cause of the partnership, but go through SDK would be something really great, anyway there's free plan with google API so...
Answered this above! But I'd also encourage you to check out mlh.link/gemini for more resources including how to snag $300 in free Google Cloud credits
Oops didn’t see thanks for the answer 🙂 will check that !
This is awesome!!!
Good luck!
太棒了！！！
Can't wait to see what others make!
Hey @konark_13, you might be able to afford earth if you win this challenge lol
That's a tempting offer for me. Need to make something useful for people on earth.
Need to think and act fast otherwise you will steal the lead and del....i mean optimize earth.😆
Na I actually gonna step this one out actually. Good luck to you though! I will be the judge to see if your product is worthy for you to buy earth. It better be something or else I am gonna dele-I mean sell earth to the highest bidder :)
I will try. I'm actually blank rn. hahaha.
You should give it a try too as you make amazing optimized solutions otherwise you have the final call for it. I was looking forward for your idea. Anyways, have a good time building something better.
