Puna Tech's 🇦🇷 'Licita Verify' by @arrozdev addresses a broken system:
Public tenders live in PDFs that offices can quietly edit after the fact
The paper trail is supposed to belong to the people auditing it. Now every milestone lands on [ARKIV] as a typed, queryable, immutable entity

I present you...
🌟 2026 @cursor_ai Vibe Coding Game Jam #vibejam

Start: Today!
Deadline: 1 May 2026 at 13:37 UTC, so you have a whole month to make your game!
REAL CASH PRIZES:
🏆 Gold: $20,000
🥈 Silver: $10,000
🥉 Bronze: $5,000
RULES:
- anyone can enter with their game
- at least 90% of code has to be written by AI
- it should be started today or after today, don't submit old games
- game has to be accessible on web without any login or signup and free-to-play (preferrably its own domain or subdomain)
- multiplayer games preferred but not required!
- can use any engine but usually @ThreeJS is recommended
- NO loading screens and heavy downloads (!!!) has to be almost instantly in the game (except maybe ask username if you want)
- add the HTML code on the Google form in the reply below to show you're an entrant
- one entry per person (focus on making one really good game!)
WHAT TO USE:
- anythign but we suggest @cursor_ai's Composer 3 and @boltdotnew, they are both fast, affordable and great at ThreeJS and making games
THE JURY:
Me, @s13k_, and I will ask some real game dev and AI people to jury again too
Sponsors and jury suggestions still very welcome, just DM me!
It will be interesting to see the difference in quality with last year, and the Vibe Jam can be kind of like a fun benchmark for AI coding seeing it close in on real commercial games I think
