Now that everyone can build, what's your unfair advantage?
Unfair Weekend is a four-day vibecoding hackathon in Vilnius for young builders, designers, domain experts, operators and future founders ready to turn sharp ideas into products people actually want.
This isn't about making the most complicated thing in the room. It's about spotting the right opportunity and using what you know that others don't. You get frontier AI tools, 24/7 technical support, mentors, business guidance and a room full of ambitious people building alongside you.
Selected participants only. Applications ran through Luma and are now closed. Devpost is where accepted participants submit their projects.

Requirements
Submit by Saturday, November 14, 20:00 Vilnius time. One submission per team. You can edit it as often as you like until the deadline.
What to build
Anything. There's no theme. Pick a real problem you understand better than most people and ship the first working version of the product that solves it. AI tools are encouraged. Building for the Kilo Co-Found special track? Read the brief.
What to submit
- Project page. Project name, a one-sentence tagline, and a short "About the project": what it does, who it's for and how you built it, 150 words max. Add the tools you used under "Built with" and, if it's live, the link under "Try it out". Keep it tight: your video does the explaining, and this text appears on the public voting page.
- GitHub repository link. Public, or private with GitHub user Nedomas invited as a collaborator. We don't judge code quality from the repo. We use the commit history to confirm the project was started at the hackathon if questions come up. Commit early and often. One giant commit at 19:58 makes that hard to show.
- Demo video, 3 minutes max. YouTube or Vimeo, public or unlisted. This is the one thing pre-judges and public voters actually watch, so lead with the product working, not the intro. A screen recording with voiceover is fine (you have Screen Studio for free). Use it to cover:
- the idea and your vision
- what you actually built during the weekend
- why it matters: what makes it important, interesting or unique
- if you have time, why your team can build the vision further
- Slides are optional. No deck is required. If you have one, add a view link in the form.
- Your team. Fill in your team name. Add every team member to the Devpost submission and list their full names and emails in the form. Solo or up to 6 people.
- Disclosures. Confirm the project was started at the event and describe any pre-existing work (or write "None").
Special prizes
When you submit, opt into every prize your project fits. You can be considered for the main prizes and special prizes at the same time.
- Founders' Dinner with Kilo Co-Found: build within the Kilo brief (AI agents for everyday well-being).
- Best Project Built with ElevenLabs: your project uses ElevenLabs. Say how in your project page.
- Best Demo by Screen Studio: judged on your demo video.
- Most Tokens Saved by condense: decided by condense's public token-savings leaderboard. Nothing extra to submit.
