The Problem: Too Many Platforms, Too Little Time
Here's a familiar routine for the average developer looking for hackathons to join:
Open Devpost, scroll through listings. Open MLH, scroll again. Switch to HackerEarth. Then Devfolio. Then Kaggle. Then DoraHacks. Then LabLab.ai. By the time you've checked them all, an hour has passed — and half the hackathons you saw were already over, had no prize money, or required skills you don't have.
I built HackRadar to kill that routine. It's a hackathon aggregator with one focus: cash prizes only. No T-shirt giveaways, no "exposure" prizes, no swag-only events — just real money from real coding competitions.
14 Platforms, One Feed
HackRadar pulls upcoming hackathons from 14 platforms and shows them in a single, filterable feed:
Why Focus on Cash Prize Hackathons?
- Filter by what matters. Most aggregators show every hackathon — hundreds of listings where the "prize" is a T-shirt or a mention tweet. HackRadar only indexes hackathons with actual prize pools, and you can set a minimum dollar amount to instantly hide the noise.
- Real money, real motivation. Cash prizes change the dynamic. They attract better competition, better judges, and often lead to stronger projects for your portfolio. If you're going to spend a weekend hacking, you might as well compete for something that pays.
Key Features
Search Across Everything
The search bar doesn't just match hackathon titles. It searches across the full description, about section, what-to-build brief, submission requirements, and prize details. Looking for "DeFi + Solana"? Type it in and see every matching hackathon instantly.
Prize Range Filter
Set a minimum (say, $5,000) to hide the small stuff. Or set a maximum to find smaller, less competitive events where you have a better shot at winning. Combine both for your personal sweet spot.
Smart Sorting
Sort by end date to catch what's closing soon. Sort by prize amount when you're chasing the biggest pools. Or sort by start date to plan ahead.
Source Toggle
Prefer Devpost over HackerEarth? Toggle individual sources on and off to curate your feed exactly how you want it.
Known System
Mark hackathons as "known" once you've reviewed them. They move to a separate tab and stay out of the main feed — so every time you open HackRadar, you see fresh opportunities, not the same list over and over.
How It's Built
HackRadar runs on Next.js 15 with the App Router, deployed to Cloudflare Workers via OpenNext. Hackathon data lives in Cloudflare R2, refreshed by a Python crawler that runs on a schedule with multiple source plugins. The entire stack is serverless and costs almost nothing to operate. All filtering happens client-side after a single background load — no page reloads, no spinner between every search.
