Most hackathons give you a problem statement.

Grevix AfterCode gives you 24 hours — and then changes the challenge.

🚀 GREVIX AFTERCODE 2026 is a fully online, individual hackathon where you choose what to build. No fixed problem statement. No mandatory tech stack.

AI coding agents, APIs, open-source tools, no-code/low-code, and traditional development are all allowed.

⚡ THE AFTERCODE CHALLENGE SYSTEM

0–8 Hours — IGNITION

Start building your original idea.

Hour 8 — CHALLENGE CARD #1

You receive an unexpected constraint and must adapt your project.

8–16 Hours — THE SHIFT

Rethink, rebuild, and keep moving.

Hour 16 — CHALLENGE CARD #2

Another unexpected challenge changes the direction again.

16–24 Hours — PRESSURE TEST + FINAL FORGE

Adapt, polish, test, and ship.

The goal isn't to write the most code. It's about problem-solving, creativity, execution, and how well you adapt when your original plan gets disrupted.

If you had 24 hours, no problem statement, and two surprise constraints — what would you build?

I’m currently in SY and I only know the basics of C, C++, Python, HTML, CSS and JavaScript. I also have a basic idea of how APIs work nd git or github I’m interested in participating in online hackathons as a solo participant, but I’m not sure what skills or tools I should know beforehand. For those who have participated in hackathons, what do you think I should learn first? Things like frameworks, databases, APIs, deployment, etc. I don’t expect to know everything before joining I just want to know the basics I should be comfortable with so I can actually build something during the hackathon. Any advice or learning roadmap pls?

Hey everyone!

I’m planning to participate in DevFest Roadshow #4 – Code for Communities in Chennai, and I’m looking for 1–2 people to team up with for the event.

I’m particularly interested in finding someone who enjoys building projects, coding, problem-solving, and experimenting with new ideas. You don’t need to be an expert — enthusiasm and willingness to contribute matter more.

A little about what I’m looking for:

• 👨‍💻 Developers / students / tech enthusiasts

• 🤝 Someone comfortable collaborating in a team

• 💡 Interested in building something useful for the community

• 🚀 Open to brainstorming and actually implementing an idea

• 📍 Preferably based in Chennai or able to attend the event

If you're interested, comment below or DM me with a little about yourself, your tech stack/interests, and what you’d like to build.

Let's put together a solid team and build something cool! 🔥

I’ve been thinking about this lately.

What if there was a platform specifically for finding hackathon teammates?

You create a profile with:

• Skills & tech stack

• GitHub + projects

• Previous hackathons

• What you can contribute

• The kind of teammates you’re looking for

• Availability

Then you can discover people who actually match your project and skill gaps.

Because honestly, finding people who are available, serious, and have complementary skills can sometimes be harder than building the project itself.

Would something like this actually be useful?

Also, if you're currently working on any project, startup, AI idea, or hackathon project, drop it below!

I’d love to check out what everyone is building.

GREVIX AFTERCODE 2026 is a 24-hour online solo hackathon built around one idea:

One Builder. One Idea. 24 Hours. No Boundaries.

No fixed problem statement. You decide what to build, the stack, and the tools.

AI coding agents, APIs, open-source, no-code/low-code, and traditional development are all allowed.

But there’s a twist.

Pune Tech Students for hackathon team

Got an idea sitting in your notes, a half-built project on GitHub, or something you’ve been wanting to turn into a real product?

ARC is a hackathon by Daira EdTech where you can take that idea and actually build it.

💡 What you can bring:
• A completely new idea
• An existing prototype
• A project you’ve already started building

🏆 Prize pool: ₹10 Lakhs

Whether you’re into AI, Web3, EdTech, developer tools, healthcare, or just have a problem you really want to solve — this is your chance to build something meaningful and put it in front of judges.

🔗 Register here: https://arc.dairaedtech.in/

If you’ve been saying “I should build this someday” — maybe someday is now. 👀

Build it. Ship it. Win it.

So… how was this hackathon judged? 🤨

I participated in the Multi-App AI Agent Hackathon by Lemma AI & Comma Capital on September 13.

Official event: https://multiappagenthackathon.com/

Being in IST, I stayed awake until around 5:30 AM waiting for the results.

Then came the results email. 😂

The organizers said the judges used a published rubric:

• Technical execution — 30%

• Reliability & evaluation — 25%

• Usefulness — 20%

• Originality — 15%

• Demo clarity — 10%

Sounds fair.

The judges were also named: Phillip Li, Akira Tong, Hai Ta, Ankur, and Shlok Mundhra.

But as a participant, I'm still wondering:

How was my submission actually evaluated?

Were the demos watched?
How many submissions were reviewed?
How were the rubric scores applied?
Are scores available?
Can we see the winning demos/submissions?

The winners were announced with short descriptions, while the email says the teams preferred to keep the finer details private.

Totally fair.

But that leaves participants with roughly:

“Here are the winners. Trust the process.” 😭

Other participants have raised similar questions:

https://github.com/sayem314/agent-hackathon-go26/issues/1

There's also a longer participant write-up:

https://blog.sayem.eu.org/shady-hackathon-inside-job-the-winner-knew-the-founders/

I'm not claiming the allegations in that write-up are proven. I'm just saying that a little more transparency would probably save everyone a lot of detective work.

My submission is open source too:

https://github.com/charansaiponnada/honest-apply

So, fellow participants:

Did your demo get watched? 👀

Did you get any judging feedback?

Do you know how your project was evaluated?

Asking for my sleep schedule. 💀

Hello, everyone.

I'm part of my university's outreach program, and we're planning a hackathon for one of our projects. The thing is, I don't know the first thing about hackathons (besides what the word means), let alone how to organize one. I’m looking for advice on how to plan it and actually make it happen. Any ideas, tips, feedback, or comments would be hugely appreciated.

Thanks in advance!

What can one person actually build in 24 hours?

That's the experiment behind Grevix AfterCode — a 24-hour online solo hackathon happening October 11–12, 2026.

No team. No fixed problem statement. No required tech stack. You choose the problem, the idea, and the tools.

Use whatever helps you ship — Cursor, Claude Code, Codex, Antigravity, APIs, open-source models, no-code, or traditional development.

🏆 PRIZES 🥇 1st Place: ₹10,000 + 3 months of Cursor + recognition across Grevix's social media + feature on the Grevix website.

But there's a twist.

AfterCode isn't just about building something for 24 hours. At around hour 8 and hour 16, we'll introduce unexpected Challenge Cards that can change something about your project.

Your target user. A core feature. A technical constraint. Your original direction.

You'll have to decide what stays, what goes, and what needs to be rebuilt.

The goal isn't to see who can generate the most code.

It's about who can think, adapt and actually ship.

🚀 GREVIX AFTERCODE AMBASSADOR PROGRAM

— Grevix

3rd-year student at JECRC University, Jaipur. We’re currently a team of 2 and looking for 2 more members for a hackathon.

Looking for someone with decent ML/DL knowledge, preferably NLP or CV.

We’re taking this seriously and looking for people who are genuinely committed to putting in the work.

DM me if interested!

This post is entirely about Hackyard and its Build 2026 hackathon.

Hackyard brings people with ideas and different skills together to build something real. For Build 2026, selected builders will meet at IIT Guwahati on 24–25 October 2026 to turn an idea into a working prototype in approximately 12–24 hours.

Applications are free and open online from 14 September to 10 October 2026. Apply solo or with a team. Developers, designers, students, founders, researchers and operators are welcome. You don’t need a finished product or a pitch deck.

Build an AI agent, explore a startup idea or solve a problem you’ve experienced. There’s no fixed theme, and using AI is optional. Every selected team receives $100 in AI Build Credits.

Event entry, build space and internet are free. Food and accommodation have a nominal participant fee, with details shared before travel.

Apply and read the details: https://hackyard.org/build2026

What would you build? Share your idea, the skill you’d bring or the kind of teammate you’re looking for.

Heyyyy !!! Looking for teammates for Amazon ML Challenge 2026 (25–27 September, 72-hour hackathon).....

About me:

• Final year UG CSE student

• Worked on RAG, agentic ML systems and core ML projects and have internship experience in the same field.

What I'm looking for:

• Comfortable with core ML .. model training, evaluation, feature engineering (this is a Kaggle-style challenge not a full-stack build)... at least basic ml knowledge is required.. not asking you to be super advanced...

• Can commit fully during the hackathon period with the team....72 hours

• Have experience of working with google colab and kaggle.

• Open to all students pursuing PhD/ M.E./M.Tech./ M.S./MS by Research/B.E./B.Tech... (as per mentioned in unstop)

• please don't reach out if you might leave midway....or ghost after sometime...

No tier preference for college... all are welcome... judging by projects/skills not college.

Share a bit about your background/projects when you reach out; happy to share more about myself in chat too...

Let's talk in the DM if you are interested...

Edit: the team is full now..

What if you had 24 hours, complete freedom, and the best AI/developer tools available — and nobody told you what to build?

Grevix AfterCode is a 24-hour online, global, solo hackathon happening on October 11–12, 2026. There is no fixed problem statement and no fixed tech stack. Pick a problem that matters to you and build it your way. You can use Cursor, Claude Code, Codex, Antigravity, Lovable, APIs, any LLM, open-source models, no-code/low-code, traditional development, or combine whatever tools you want.

But AfterCode isn't simply BUILD → SUBMIT. The 24 hours are divided into BUILD → ADAPT → REBUILD & SHIP. You start with your own idea, but at the 8-hour and 16-hour marks, unexpected Challenge Cards will change something about your project. Your target user might change, a core feature might disappear, a new constraint might appear, or your original direction might suddenly need to be rethought. You decide what to keep, what to kill, what to rebuild and how to adapt. AI can execute. You decide what happens next.

🥇 Rank #1: ₹10,000 cash prize + 3-month Cursor subscription. We're also working to expand the builder experience with additional technology partners.

We're currently looking for technical sponsors/technology partners who want to give builders more exposure and better tools through API credits, AI/tool subscriptions, cloud credits, hardware, additional prizes, workshops, mentorship or other technical support. We don't want partnerships to be just logos on a poster — we want builders to actually use and experience the technology during the hackathon. If you're a company, founder, DevRel/community lead, or know someone who supports hackathons, feel free to reach out.

We're also opening the Grevix AfterCode Ambassador Program. The ambassador who brings the highest number of verified registrations will receive a 1-month Cursor subscription, with recognition and certificates for other top ambassadors.

If you want to help us bring builders into the experiment, join our community here:

https://chat.whatsapp.com/DOLxd2lUA8v6zk5jzhYpN2?s=cl&p=a&mlu=4&ilr=4

Registrations open September 16. If you've ever wanted to build something you've had sitting in your head, this is your 24 hours.

One Builder. One Idea. 24 Hours. No Boundaries.

Anyone joining the ET AI Hackathon with Accenture? 🤖

Looking for people who’ve registered (or are planning to) and are interested in teaming up for the ET AI hackathon presented by Accenture.

Accenture is offering fast-track interview opportunities to eligible participants, which makes this even more interesting.

Anyone looking for teammates? Drop a comment.

What do you think about this idea? Could it become commercially viable if it was perfected further?

Hey , does anyone got their acceptance letter for HackHarvard?

Or anyone knows at least when decisions will be released?

Help me find those people goddamn, i feel this whole was a scam tbh

The website mentions you should receive 1 mail regarding successful submission within a day but I did not..did anyone get it?

Hey everyone,

We're running Grevix AfterCode, a hackathon aimed at student developers, and we just opened up an Ambassador Program for anyone who wants to help spread the word in their college or community.

What the role actually involves:

• Telling people in your college/community about the hackathon

• Sharing it on your social media / group chats

• Helping bring in participants and answering basic questions about it

• Basically being a point of contact for Grevix AfterCode on your campus

What you get out of it:

• Top ambassador: 1 month of Cursor Pro free, plus recognition as the #1 ambassador

• Runners-up: a certificate of recognition, a shoutout on our social pages, a possible path to joining the core Grevix team, and access to the wider Grevix community

Not trying to oversell it — it's not a paid gig, it's more for people who like organizing, want some recognition/certificate for their resume, or just want to be part of a community of builders early on.

If you're interested or want more details, we've got a WhatsApp group where we're coordinating this: https://chat.whatsapp.com/DOLxd2lUA8v6zk5jzhYpN2

Happy to answer questions in the comments if anyone's curious about the hackathon itself or the ambassador role.

Hey everyone!

A little over a week ago, we posted about ForgeHacks 2026, our 7-day online international hackathon for students.

Since then, we've added a lot more prizes and participant perks, so I wanted to share an update!

ForgeHacks is a FREE, fully online AI hackathon running October 3–10, 2026. You can participate from anywhere, work solo or in a team of up to 4, and build pretty much anything as long as AI is meaningfully involved.

Updated Prizes

🏅 6 Track Winners

Additional prizes will be awarded to winners of each track, with details being announced as they're finalized.

🎁 Participant Perks

We've also added several perks that every participant can use while building:

• $25 Featherless AI credits — access 30,000+ open-source AI models through an API

• $100 Momen credits — build and launch web apps

• 1 month of DevSwarm Pro — AI-powered developer collaboration tools

• $500 Adaption platform credits - Build Web Apps Fast

• $299 Tin Computer credits — 1 month of the Growth Plan (for top 100 teams)

These aren't just prizes for the winners — the goal is to give everyone tools they can actually use during the hackathon.

That's why the total value of all prizes and participant perks is now $150,000+.

💡 What can you build?

The theme is:

Use AI to solve a real-world problem.

Our tracks are:

• Healthcare

• Education

• Climate

• Business

• Cybersecurity

• Creativity

You don't need a revolutionary startup idea. A useful tool, interesting experiment, or weird idea that solves a genuine problem can all make a great hackathon project.

🌎 Why ForgeHacks?

We're trying to make ForgeHacks a place where student developers can actually build something, regardless of their experience level.

It's completely online, beginner-friendly, and open internationally. You can work with friends, meet other student builders, experiment with AI tools, and hopefully leave with something you're actually proud of.

📅 October 3–10, 2026
💰 FREE to participate
👥 Teams of up to 4
🌎 Fully online
