What is Major League Hacking (MLH)?
Major League Hacking (MLH) is the official student hackathon league, powering over 200 weekend-long invention competitions annually across North America, Europe, Asia, and Africa. Founded in 2013, MLH has become the gold standard for high-quality, beginner-friendly hackathons.
MLH doesn't just list events—they organize, sponsor, and run them. Every MLH event follows strict quality guidelines: free attendance, inclusive culture, experienced mentors on-site, and transparent judging. For students, this means you're guaranteed a well-run experience, not a chaotic weekend.

Why MLH is Essential for Hackathon Success
MLH hackathons are free, beginner-friendly, and specifically designed for students. Unlike general hackathons that may charge fees or expect professional-level projects, MLH events welcome first-timers with workshops, mentors, and swag. Many attendees code their first project ever at an MLH event.
The MLH network is also a recruiting pipeline. Sponsors like GitHub, Google, Microsoft, and Meta attend to scout talent. Winning or even participating in an MLH hackathon can lead to internship offers, especially if you showcase your project on LinkedIn and tag sponsors.
- 200+ hackathons per year across 5 continents, all with verified quality standards
- Free attendance, travel reimbursements, and meals provided at most events
- MLH coaches on-site at every event to help debug, mentor, and answer questions
- Hardware lab with Raspberry Pis, Arduinos, VR headsets, and more (borrow for free)
- Exclusive sponsor challenges with bonus prizes (e.g., "Best use of Twilio API" = $500)
- Community Slack with 150K+ hackers for team formation and networking

How to Use MLH for Your Hackathon Journey
Start by browsing the MLH Season calendar at mlh.io/seasons. Events are organized by semester ("MLH Fall 2024," "MLH Spring 2025"), making it easy to plan ahead. Filter by location (in-person vs. virtual) and check eligibility—most require you to be a current student.
Register early—popular events like PennApps, HackMIT, and TreeHacks fill up in hours. After registering, join the event Discord or Slack. Teams often form there before the event, so introduce yourself, share your skills (frontend, backend, ML, design), and find collaborators.
- Visit mlh.io/seasons and filter by your region or virtual events
- Read the event description carefully—note travel reimbursement policies and themes
- Register ASAP (some events use lottery systems, others are first-come)
- Join the pre-event Discord/Slack to find teammates and learn about workshops
- Check sponsor challenges before the event—plan your project around bonus prizes
- Arrive to opening ceremony on time—MLH coaches introduce tools, APIs, and rules
- Submit to Devpost by the deadline (MLH events use Devpost for all submissions)

Pro Tips for MLH Events
MLH events are highly competitive, but they're also incredibly supportive. Take advantage of workshops—learn new tools like Firebase, Figma, or OpenAI APIs during the event. Coaches are there to help, so don't hesitate to ask for debugging help or architecture advice.
Focus on sponsor challenges if you want to maximize prize opportunities. Many MLH hackathons have 10+ sponsor prizes on top of the main awards. For example, winning "Best Use of MongoDB" might earn $1,000 even if you don't win overall. Read challenge descriptions carefully and integrate sponsor tools genuinely (judges can tell if you force-fit).
- Attend the opening ceremony workshop—sponsors demo their APIs and tools
- Use the MLH hardware lab to prototype IoT or VR projects (free checkout)
- Tag @MLHacks on Twitter/X when you ship—they retweet and amplify cool projects
- Take breaks: MLH events have games, karaoke, and midnight snacks to recharge
- Submit to multiple sponsor challenges (one project can win several categories)
- Network with other hackers—exchange contacts, many form long-term teams

Beyond the Weekend: MLH Fellowship & Community
MLH also runs the MLH Fellowship, a remote internship program where you contribute to open-source projects, build portfolio projects, or work on production codebases at startups. It's a great way to gain real-world experience if you can't land a traditional internship.
The MLH community extends beyond events. Join the MLH Discord to stay connected with hackers worldwide, get notified about new seasons, and participate in online mini-hacks. Many students credit MLH with launching their tech careers—it's more than just hackathons, it's a movement.
