This Devpost hackathon page is intended only for those who have been formerly accepted for participation in the Code4Green hackathon via Awardforce. You should have received the link for this hackathon page only by the Code4Green organising team via Slack or direct email, or by one of your team members. Please let us now if you gained access to this page by any other way.

Participants: Individuals must be at least 18+ years old and must be resident in a European country during the entire time of the hackathon (regardless of their nationality).

Teams: Teams are composed of 4-6 people. The initial application process supports team applications of up to 3 people. The exceeding team members will be selected by the organising team.



All teams need to submit their final projects to Devpost and their code to GitHub latest by Sunday 12 July 2020, 10:59 CEST. Please note that submissions after this deadline will not be considered for the final evaluation by the jury.

What to submit to Devpost:

Your team must create a dedicated project channel on the Code4Green Devpost webpage. The final evaluation of your project is based only on everything you have submitted to your Devpost project channel (including links to your video and GitHub account). Your Devpost project channel should include:

Project title:





Project description:

Describe your project, including the final goal of your project, what target audience / beneficiaries it refers to, what you have done so far, and what there is left to do. Please keep in mind the juding criteria when describing your project:

- Degree of innovation;

- Sustainability;

- Social benefit;

- Technical implementation;

- Presentation.


GitHub direct link for code

Please post a link to a GitHub account in which you post all code that you composed or used during the creation of your project. Please use a private GitHub account for that.


Pre-recorded video pitch

Post a link to a video pitch, in which you briefly (max. 2 min) and creatively present your project. Devpost allows direct video embedment of YouTube and Vimeo, but you can use any videohoster you prefer (as long as they stay within reason and consideration of our Code of Conduct). In any case, please post the direct link in addition to an embedded video. Only the first 2 minutes of a video will be considered for the final evaluation by the jury.

Hint: We do not expect Hollywood production quality, as every participating team should have the same chances regarding their technical equipment. What's important is that the viewer gets a condensed overview of your project and why it should win the hackathon. What counts is a sympathic and useful take on your project - not the expensive audio and video equipment.


Open-source and open-data

Our hackathon promotes the use of open-source and open-data to create sustainable digital solutions that will last. For this, you and your team are asked to upload your final solutions to Devpost and any accompanying code to GitHub, both under an open-source license. All outcomes of the hackathon will therefore be open-source and available to the public. Please note, that projects that are uploaded without open-source availability will not be considered for the final evaluation by the judges.

This requirement is limited only to the duration of the hackathon. If you wish to develop your project further after the event, or are one of the winning teams receiving additional mentoring, you will not need to update any further developments under an open-source license. We do however want to emphasise the many benefits that arise from maintaining your project(s) in an open-source manner.


*All above mentioned times are in 24h-format CEST.
