Before the Hackathon

Attending your first hackathon can feel overwhelming, especially if you’re new to building projects under time pressure. This guide outlines what to expect and how to prepare so you can focus on learning, building, and enjoying the experience.

What is a Hackathon?

A hackathon is a time-boxed event, typically 12–48 hours, where participants design and build a software or hardware project from scratch. Hackathons are commonly hosted by universities, companies, or tech communities.

• Participants work individually or in teams

• Projects are built during the event timeframe

• Events often include themed tracks (e.g., AI, sustainability, fintech)

• Teams present demos to judges at the end

• Awards are given for creativity, impact, or technical execution

Because of the limited time, judges prioritize:

• Original or compelling ideas

• Clear problem–solution alignment

• Functional demos with strong presentation

A polished concept with a working demo usually scores higher than an ambitious but incomplete system.

How to Prepare

1. Define Your Goal

Before attending, decide what success looks like for you. Common goals include:

• Building a specific idea you’re passionate about

• Learning a new technology or framework

• Networking with peers and sponsors

• Competing to win a prize

If you are joining as a team, align on a shared objective early. Misaligned expectations are a common source of hackathon friction.

2. Set Up Your Development Environment

Hackathon time is extremely limited. Environment setup during the event wastes valuable building time.

Before the hackathon:

• Install your IDE or editor

• Install required languages/runtimes (Node, Python, etc.)

• Install Git and setup your GitHub credentials

• Verify package managers work (npm, pip, etc.)

• Test a minimal project build/run locally

You may not write project code beforehand, but preparing your tooling is always allowed and strongly recommended.

3. Choose Your Tech Stack in Advance

Avoid debating languages or frameworks during the hackathon.

Select:

• Primary language

• Frontend framework

• Backend framework

• Database (if needed)

• Hosting/deployment option

The best stack is usually:

• Familiar to your team

• Fast to prototype with

• Easy to deploy

Hackathon Execution Strategy

Strive for Simplicity

Time constraints are the defining factor of hackathons.

Prioritize:

• A narrow problem scope

• One or two core features

• A working end-to-end flow

Avoid:

• Complex architectures

• Over-engineering

• Large feature sets

UI Matters More Than You Think

Judges typically see your project for only 1–2 minutes.

A strong UI:

• Makes the project immediately understandable

• Signals completeness and polish

• Improves perceived quality

Focus on:

• Clean layout

• Clear user flow

• Visual feedback or animations

• Demo-friendly screens

A visually compelling interface significantly improves judging outcomes.

Use a Monorepo When Possible

For small teams under time pressure, a monorepo simplifies coordination.

Advantages:

• Single repository setup

• Shared types and models

• Easier deployment

• Faster onboarding for teammates

Frameworks like Next.js, Supabase, or full-stack templates allow frontend and backend development in one codebase, reducing integration overhead.

Collaborate with Branches and Frequent Merges

Parallel development is essential in short events.

Best practices:

• Each feature on its own branch

• Merge frequently into main

• Resolve conflicts early

• Keep main deployable

Avoid long-lived branches, integration issues compound quickly in hackathons.

Final Thoughts

Hackathons are intense by design. Expect fatigue, uncertainty, and time pressure, these are normal parts of the experience.

Focus on:

• Learning

• Building something functional

• Collaborating effectively

• Presenting clearly

Even if your project is incomplete, the skills and experience gained are the real outcome.
