Winners Announced:
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!
Our Prompt
With Earth Day just around the corner, we welcome you to build something inspired by the planet.
Please interpret this prompt however you’d like. Honoring your favorite green spaces? Solving carbon emissions? Reimagining our entire planetary relationship? Any angle is fair game!
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.
