हैकाथॉन क्या है?

the short definition

A hackathon is a competition with a deadline. Organisers set a theme and a time limit, participants form teams, and every team spends that time turning an idea into something that runs. At the end each team demonstrates what it built, judges score the entries against published criteria, and prizes go to the strongest.

Four things make an event a hackathon rather than a workshop or a conference: it is time-boxed, work happens in teams, the output is something built during the event, and it is judged. An event missing any of the four is usually called something else on its own listing — a workshop, a bootcamp, a meetup — and this directory follows whatever the organiser called it.

what the word means

“Hackathon” is hack plus marathon. “Hack” here is the old engineering sense — a quick, clever solution to a problem — not intrusion into a system. “Marathon” describes the format: one continuous, bounded stretch of time rather than a series of sessions. Indian listings are almost always in English; the Hindi हैकाथॉन appears on some campus posters and on the Hindi pages of this site, and this directory reads both.

how a hackathon runs

The order is close to the same everywhere:

• Kickoff — the organiser sets out the theme, the rules, the judging criteria and the deadline.
• Team formation — people either arrive as a team or form one on the spot.
• Building — the bulk of the time, usually with mentors on hand.
• Submission — work stops at a hard deadline and teams submit whatever state their project is in.
• Demos — each team presents, typically in a few minutes.
• Judging and prizes — judges score against the criteria set at kickoff and announce winners.

the kinds of hackathon run in India

The word covers events that differ a lot in who turns up, how long they run and what is at stake. Knowing which kind a listing is tells you most of what you need before registering.

• Campus hackathons — this is the calendar: the IITs, NITs, IIITs, BITS Pilani, VIT, SRM, Manipal and hundreds of engineering colleges run weekend events through their coding clubs and E-Cells, and the Smart India Hackathon — the government's national student programme — is the largest single event of the year by a wide margin. Beginner tracks and free entry are the norm.
• Platform-hosted competitions — a genuinely Indian pattern: Unstop, Devfolio, HackerEarth and Internshala host thousands of online and hybrid hackathons where organisers list free, which is why the SERP belongs to them and why this directory records them as sources rather than pretending to replace them.
• Corporate and fintech challenges — banks, the UPI ecosystem, the IT services majors and the GCCs in Bengaluru and Hyderabad set briefs tied to their own products, with cash prizes in lakhs and a hiring angle.
• Civic and open-data events — NITI Aayog, state IT departments and city administrations run open-government-data and GovTech briefs, often hybrid.
• Startup and community weekends — T-Hub, the coworking floors of Koramangala and Powai, and the developer communities run short, free events announced late, which is why the calendar is worth checking more than once.
• Game jams — the same format producing a game instead of an app, clustered around Global Game Jam in January and the Bengaluru and Pune indie scenes.

The name shifts with the subject: a dataset makes it a datathon, a game makes it a game jam, an ideas-only event with no build is an ideathon. The shape is the same — a brief, a clock, teams, a demo — and this directory lists events under whatever the organiser called them.

how long they last

There is no standard length — the organiser sets it. Of the 47 hackathons listed on this site right now, 23 run inside a single day and 24 run across two or more. The longest currently listed is VoltHacks, which runs 116 days (22 May – 14 Sep 2026).

The two shapes you will meet most often in India are the weekend build of 24 or 48 hours, which starts on a Friday evening or Saturday morning and finishes with demos on the Sunday, and the single working day, which is what most corporate challenges and community events run. Shorter events are built around a narrow brief you can finish in one sitting. Longer ones leave room for a bigger build and normally put food, sleep and mentor sessions in the schedule.

what it costs to enter

Less than people expect, and almost always nothing — free entry is the norm here. 34 of the 47 hackathons listed on this site publish a free ticket, and 13 have not announced one yet. Where an organiser has published a figure it is on the listing, so you can check before registering.What a ticket price does not tell you is capacity: free events at universities and coworking spaces routinely cap places and close registration early.

do you need a team

Almost always, and the organiser sets the size rather than leaving it open — it is one of the first things stated on a listing, because it decides how you show up. The limits vary more than people expect, from a pair to a room, so read the one on the event you are entering rather than assuming. If you arrive alone, most events run a team-forming session at kickoff.

in person or online

Worth checking before you plan around one. Of the 47 hackathons listed here, 34 are in-person and 1 is hybrid, which still means a session you attend in the host city, and 12 run entirely online. The practical question is usually which host city you can get to, which is what the sections below are for.

where they happen in India

Not evenly. This directory groups every listing into ten city hubs, and each hub covers the campuses and satellite towns around it rather than the city alone — an event in Whitefield or Electronic City is listed under Bengaluru, one in Gurugram or Noida under Delhi NCR, one in Hinjewadi under Pune. That is why a city you can reach in an hour is worth checking even when your own town has nothing. Ten further cities — Kochi, Thiruvananthapuram, Coimbatore, Indore, Bhopal, Lucknow, Bhubaneswar, Visakhapatnam, Nagpur and Guwahati — are too far from any hub to be folded into one honestly, so they keep their own names in the listings instead.

The ten hubs are Bengaluru, Hyderabad, Delhi NCR, Mumbai, Pune, Chennai, Kolkata, Ahmedabad, Jaipur and Chandigarh, and each page says exactly which suburbs, campuses and states it covers. Kerala, the north-east and the tier-two cities of the interior are deliberately left out of that grouping — an event in Kochi, Thiruvananthapuram, Coimbatore, Indore or Bhopal keeps its own city name and shows under all events.

the types you'll see listed

Hackathons are usually named for their subject or their audience. These are the filters this directory keeps, with what is on each right now:

ai hackathons

A listing appears here when the brief is artificial intelligence — agents, models, machine learning, computer vision, generative AI — either named in the title or clear from the organiser's own description. (39 listed)

student hackathons

A listing appears here when the organiser restricts entry to students, runs the event on a campus, or names a university, college or student society as the host. (6 listed)

game jams

A listing appears here when teams build a game inside a fixed time limit — video games or tabletop, solo or team, from a theme or a constraint handed out at the start. (0 listed)

Events are also split by format — in person, online or hybrid — and by city. You can browse every listing by city from the locations index.

who can enter

Hackathons are open to more than programmers: teams that win are usually a mix of engineering, design and someone who can present the idea clearly. Plenty of events are aimed squarely at people who don't write code, and say so in their own description — several of the ones listed here are built around no-code and AI-assisted tools, which is a fair part of why the format has stopped being a programmers-only event.

One of the hackathons listed here is tagged beginner-friendly by its own organiser — Hack Knowvy - 1. If it is your first one, scope small: a finished small idea demos far better than an ambitious half-built one, because judging happens on what actually runs.

what you can win

Prizes are set per event and published on the listing. They are not always cash — mentoring, cloud credits, hardware, an incubator place and introductions are all common — and the amount varies enormously between a community jam and a sponsored event.
