The best online hackathon platforms are Devpost, Devfolio, MLH, Unstop and Hack2skill, which list events, handle registrations and collect submissions. Hackathons exist to turn ideas into working prototypes quickly, while building skills and connections. I have competed in 10+ hackathons and founded the TechVerse Enclave community, so this page covers platforms and websites, the point of hackathons, hackathon programs, mentoring and finding mentors, attending, planning, hackathon season and ISRO's hackathon.
What is the best online hackathon platform?
Devpost is the largest global platform for online hackathons, Devfolio is popular in India and Web3, MLH lists student events worldwide, Unstop covers Indian college competitions, and Hack2skill runs many government and corporate hackathons.
For organisers, choose by audience and features: Devfolio offers applications, judging and project pages; Devpost provides large reach and gallery pages; Hack2skill supports large-scale government challenges. For participants, the best platform is the one listing events in your interests and region. Create profiles on two or three, enable notifications for themes you like, and keep your past projects visible there, since judges and recruiters browse them. Discord servers usually handle real-time communication.
What are the best hackathon websites?
Good websites for finding hackathons include Devpost, MLH's events page, Devfolio, Unstop, Hack2skill, HackerEarth, Kaggle for data competitions, lu.ma for community events, and official pages for government challenges such as Smart India Hackathon.
Each serves a niche: MLH for student events with codes of conduct and beginner support, Kaggle for long-running machine learning competitions, HackerEarth for corporate hiring challenges, and Devfolio and Unstop for Indian college events. Aggregator newsletters and community Discord servers also share opportunities. Bookmark a few, check them weekly, and register early, since popular events fill quickly or close applications weeks before the start date. Follow organisers on LinkedIn as well.
What is the point of a hackathon?
The point is to build something useful quickly: teams turn an idea into a working prototype within a fixed time, learning, collaborating and testing ideas faster than normal projects allow.
For participants, hackathons build practical skills, portfolios, confidence and networks. For organisers and sponsors, they generate ideas, test developer tools, discover talent and engage communities. Governments use them to source solutions to public problems, and companies use internal hackathons to spark innovation outside normal roadmaps. The time pressure forces focus: teams must decide what matters most and cut everything else, a skill that transfers directly to real product work. Many startups and lasting friendships began this way.
What is a hackathon program?
A hackathon program is the structured plan of an event: registration, opening ceremony, problem statements or tracks, team formation, building periods, mentor sessions, workshops, submission deadline, judging rounds and a closing ceremony with prizes.

Some organisations also run longer hackathon programs, such as multi-stage national challenges with idea submission, shortlisting, prototype development and grand finales, or recurring corporate innovation programs where winning ideas receive funding and mentoring. Smart India Hackathon is an example of a multi-month national program. A good program publishes timelines, rules, judging criteria and support channels in advance, so participants can plan their time and expectations. Check the schedule before registering so you can commit fully.
How do you mentor at a student hackathon?
Help teams scope, unblock and present, without building for them. Ask what problem they are solving and what a working demo looks like, suggest cutting features, help debug blockers, and give pitch feedback before judging.

Walk around regularly rather than waiting to be asked, since beginners hesitate to request help. Ask questions that guide thinking: who is the user, what is the core flow, what can you finish by tonight? Share quick technical tips, such as deployment shortcuts or API usage. Encourage teams who struggle, and remind everyone to rest. Before demos, run practice pitches and help teams explain clearly what they built and what remains mocked.
How do you find a mentor or guide for a hackathon?
Ask event organisers, who usually provide mentors during the hackathon; reach out to seniors, alumni and faculty who have competed before; and join community servers where experienced hackers help newcomers.
Also asked as: looking for a mentor/guide for hackathon
Before the event, find one person who can review your idea and tech stack; during it, use official mentor office hours actively. When asking, be specific: share your problem statement, approach and the exact blocker. Student communities, such as TechVerse Enclave, which I founded, and college coding clubs are good places to meet experienced members. Mentors value teams that come prepared, act on advice and report back, which also builds lasting relationships.
How do you attend a hackathon?
Find an event, check eligibility, register before the deadline, form or join a team, and prepare your laptop and tools. On the day, attend the opening session, build, use mentors, submit before the deadline and present your demo.
Also asked as: how to attend hackathon
For in-person events, bring a laptop, charger, extension cord, ID, water bottle and something warm for night sessions. For online events, test your internet, camera and screen sharing, and join the Discord early. Read the rules about pre-built code and AI tools. Introduce yourself to others, attend workshops, and talk to sponsors. Afterwards, publish your project on GitHub and share what you learned, which turns attendance into lasting portfolio value.
How do you plan a hackathon?
Decide the purpose, audience, format and size; set dates and a budget plan; secure a venue or platform, sponsors, mentors and judges; prepare themes, rules and judging criteria; then market the event and manage registrations.
Also asked as: how to plan a hackathon
Create a timeline: three months out for sponsors and venue, two months for mentors and judges, six weeks for registrations, and two weeks for final logistics. Plan food, Wi-Fi, power, accessibility, safety and a code of conduct. Recruit volunteers with clear roles. Prepare starter resources, API credits and workshops. After the event, publish results, collect feedback, and share highlights to build momentum for the next edition.
When is hackathon season?
Hackathons happen all year, but student hackathon seasons follow academic calendars: in India, many college events cluster from August to March, and in North America, the MLH season runs roughly from late summer to spring.
Online hackathons and corporate challenges run continuously, and national programs such as Smart India Hackathon follow their own multi-month cycles, typically with finales around December in recent years. Summer often brings online and corporate events, since students are free. October brings Hacktoberfest, an open-source contribution event rather than a typical hackathon. Follow platforms and set alerts, and plan around exams, since the busiest hackathon months often overlap with academic deadlines.
Is ISRO's hackathon online?
ISRO's Bharatiya Antariksh Hackathon, run with Hack2skill, has used online rounds for registration, idea submission and early evaluation, with shortlisted teams progressing to later stages. Check the current edition's official rules for exact formats.

Problem statements typically involve space technology, satellite data, remote sensing and related applications, so teams benefit from skills in data science, computer vision and geospatial analysis. Follow ISRO's official announcements and the Hack2skill event page for dates, eligibility and team rules, and avoid unofficial sources. Even if you are not selected, working with satellite datasets from public Earth observation portals builds valuable skills for space and climate technology careers.
