Hackathon Preparation Checklist 2026: Everything to Do Before, During, and After

80% of hackathon success is preparation. Teams that show up with a plan, pre-configured tools, and clear roles outperform teams that figure things out on day 1. Use this checklist.

1 Week Before

  • [ ] Team formed and roles assigned
  • [ ] Problem statements/tracks reviewed (if available)
  • [ ] Tech stack decided (what framework, what database)
  • [ ] Starter kit/boilerplate ready (auth, DB, deployment pre-configured)
  • [ ] AI tools installed: Cursor, Claude, Copilot
  • [ ] Deployment pipeline working (push to GitHub = live on Vercel/Railway)
  • [ ] API keys obtained: AI APIs, maps, any external services
  • [ ] Design system picked (shadcn/ui, Tailwind components)
  • [ ] Laptop fully charged, charger packed, extension cord ready
  • [ ] Snacks, water bottle, comfortable clothes prepared

Day Before

  • [ ] Final team sync: who builds what, hour-by-hour plan
  • [ ] Git repo created, all members have access
  • [ ] Test deployment works (deploy empty project, verify URL)
  • [ ] Backup plan: what if primary idea doesn’t work?
  • [ ] Read the rules: submission format, judging criteria, deadlines
  • [ ] Sleep well (seriously – tired teams make terrible decisions)

During the Hackathon

First 2 Hours (Plan)

  • [ ] Understand the problem statement completely
  • [ ] Sketch the user flow (5 screens max, paper is fine)
  • [ ] Define MVP: what’s the ONE thing the demo must show?
  • [ ] Split tasks among team members
  • [ ] DO NOT start coding until plan is clear

Hours 2-20 (Build)

  • [ ] Frontend and backend work in parallel
  • [ ] Deploy by hour 6 (even if half-broken)
  • [ ] Use AI for ALL boilerplate – don’t hand-write CRUD
  • [ ] Check in every 4 hours: “Can we demo right now?”
  • [ ] If stuck for 30 min, ask mentors (that’s what they’re there for)

Hours 20-30 (Polish)

  • [ ] STOP adding features – polish what exists
  • [ ] Add loading states, error messages, empty states
  • [ ] Fill with realistic data (Indian names, real-looking content)
  • [ ] Test on mobile (judges often check on their phones)
  • [ ] Fix the top 3 bugs only (don’t chase all of them)

Last 6 Hours (Present)

  • [ ] Write pitch script (3 minutes max)
  • [ ] Assign who presents, who demos, who answers questions
  • [ ] Practice 3 times – time it each time
  • [ ] Record backup demo video (in case live demo crashes)
  • [ ] Prepare for 3 most likely judge questions

After the Hackathon

  • [ ] Polish project for 1 week – fix bugs, write README, add screenshots
  • [ ] Deploy to custom domain if possible
  • [ ] Pin on GitHub profile
  • [ ] Post on LinkedIn with demo video
  • [ ] Write a blog post about what you built
  • [ ] Connect with teammates, mentors, judges on LinkedIn
  • [ ] Register for next hackathon (momentum matters)
