Four platforms come up constantly, and they're not interchangeable: each has a real specialty. Here's what actually separates them.
Unstop: broadest format coverage for Indian students
Unstop (formerly Dare2Compete) is less a hackathon platform and more a general competition platform: hackathons, case studies, quizzes, and skill-based assessments all live here, with a large Indian student user base and strong college partnerships. A meaningful share of what's listed ties directly into corporate hiring: companies use it as a discovery and assessment layer, not just an event board. If you're looking for something outside pure coding, a case competition, a quiz, a design challenge, Unstop is where most of that inventory sits.
Devpost: largest by volume, strongest globally
Devpost is the biggest hackathon platform by sheer number of listings and the most globally recognized, particularly in North America and Europe. Its strength is discovery and project showcase: a clean submissions page, a public gallery of past projects, and genuinely global reach. What it doesn't offer is Unstop's breadth of formats: Devpost is close to purely a listing and hosting platform, without case studies or quizzes attached.
Devfolio: the Web3 specialist
Devfolio has built a specific, strong reputation in the Indian college hackathon scene, and it's the default choice for blockchain and crypto-themed events. It's the platform ETHIndia itself runs on. Ethereum integration and a UI built around that community make it the natural pick if you're specifically building in Web3, even though its general hackathon listings extend beyond crypto too.
HackerEarth: built for recruitment
HackerEarth combines coding assessments with hackathon-style challenges and leans enterprise. It's primarily used by large companies running recruitment-oriented hackathons and technical screening. If the hackathon you're looking at is explicitly tied to a hiring pipeline, HackerEarth is a common host for that specific format.
Quick pick
- Web3 or blockchain specifically: Devfolio
- Recruitment-oriented, corporate hiring focus: HackerEarth
- Largest global pool, North America/Europe-heavy: Devpost
- Broadest range of formats for Indian college students, including non-hackathon: Unstop
Or don't pick, check all of them at once
None of these platforms lists everything, which is the actual problem with checking just one. brabble.ai merges live listings from Unstop, Devpost, Devfolio, HackerEarth, MLH, DoraHacks, Hack Club, ETHGlobal, and more into a single daily-refreshed feed, so instead of bookmarking four separate platforms and checking each one, one page covers what's currently open across all of them.
