Hackathons — every open hackathon in one deadline-sorted feed

Find upcoming hackathons from Devpost, Hack Club and Major League Hacking in a single searchable list, ranked by what closes first. Filter by prize, format, theme and eligibility. Free, no account, no paywall.

Also available as a public JSON API — see Using the data.

Why this exists

Every hackathon platform shows you only its own inventory. Devpost has no high-school events. MLH has nothing corporate. Hack Club is high-school only. Devfolio skews India and web3. So finding "an AI hackathon closing in the next two weeks that I'm actually eligible for" means checking five sites and merging the results in your head.

This is the neutral index above those platforms. Three things nobody else does:

• Sorted by deadline, not by recency or whatever the platform is promoting. The question builders actually ask is "how long do I have?"
• Filtered by eligibility — age, student status, region, invite-only. The single biggest source of wasted clicks.
• Cross-platform and neutral. Listings link straight to the organizer. This site never sits in between, and has no inventory to favour.

How it works

GitHub Actions (4×/day, free tier)
  └─ scripts/ingest.mjs      fetch every source, normalize, dedupe, sort
  └─ scripts/validate.mjs    quality gate — blocks bad data from publishing
  └─ commits public/events.json
       └─ Netlify rebuilds and serves it from the CDN edge

No server. No database. No API keys. No secrets. The deployed site is a static bundle that fetches one JSON file; freshness comes from CI, not runtime infrastructure. The whole thing runs on free tiers at any traffic level Netlify serves.

Sources

Source	Method	Covers
Devpost	Unauthenticated JSON API	Online + corporate-sponsored, large prize pools
Hack Club	Public JSON API (pre-geocoded)	High-school events worldwide
Major League Hacking	HTML parsing	Sanctioned collegiate events

Sources fail independently. A broken adapter degrades coverage and is surfaced in the UI — it never breaks the build.

Quick start

git clone https://github.com/jongan69/hackathons.git
cd hackathons
npm install
npm run seed     # realistic dataset from captured fixtures
npm run dev      # http://localhost:5173

Commands

Command	What it does
npm run dev	Local dev server
npm run build	Type-check and build for production
npm run seed	Build public/events.json from captured fixtures
npm run ingest	Fetch live data from all sources (needs network access)
npm run validate	Data quality checks
npm run test:parse	Parser regression tests (39 assertions, no dependencies)
npm run check	Tests + lint + production build

seed exists because ingest needs outbound access to Devpost, Hack Club and MLH. In a restricted environment, seed gives you a realistic dataset to build against.

Using the data

public/events.json is served CORS-open. Build on it — bots, Discord integrations, newsletters, whatever. No key, no rate limit, no attribution required (though a link back is appreciated).

Example: hackathons closing this week with a real prize

const { events } = await fetch('https://hackathons.dev/events.json').then(r => r.json());
const week = Date.now() + 7 * 864e5;

events
  .filter(e => e.prizeUsd > 1000 && new Date(e.endsAt) < week && !e.inviteOnly)
  .forEach(e => console.log(e.prizeLabel.padEnd(12), e.title));
