It's been a great year for the Devpost community:

• We hosted 809 online & in-person hackathons, at which participants from 155 countries submitted 25,629 projects, winning $8.75 Million in prizes!

• The top 5 project tags were Javascript, Python, HTML, CSS, and Node.js. No surprises there. ECMAScript is life.

We saw some pretty neat hacks:

• Adva Levin's Kids Court took top prize at the Alexa Skills Challenge: Kids by teaching kids how to work out their arguments in a healthy way.

• Konstantinos taught us how to use a longsword using IoT, Voice, and deep learning.

• And in May, one precocious hacker unintentionally DDoS'd us. We're not mad, but please don't try that at home.

We worked on hackathons with Amazon, Microsoft, Facebook, TechCrunch, The Real Estate Board of New York, the Philadelphia Museum of Art, Appian, UiPath, Xero, and tons of other awesome partners!

Of course, we couldn't do any of this without you. Happy Holidays, Happy New Year, Happy all the things. We'll see you in 2019!

Online hackathons


Agora HolidayHack

Agora is closing out the year with a bonus online hackathon with $2,000 in cash prizes + lots of swag.

All you have to do is build an app or website that uses the Agora real-time-communications (RTC) platform. Use RTC to solve a real world problem, re-invent the future, or simply be creative!

This challenge ends Dec 30th!


Microsoft Graph Security Hackathon

Corporate security is tough. While most companies use a variety of specialized tools to audit their attack surface, investigate attacks, and secure devices & user data, these tools aren't designed to communicate with each other.

Siloed software leads to hacky integrations which at best, don't work well and at worst, provide a false sense of security.

But, Microsoft believes you can solve these integration challenges using their new Graph Security API and is offering $15,000 in prizes to prove they're serious!

This API is a unified REST endpoint that makes it easy to access & act on security insights from an ecosystem of connected security solutions.


Amazon Alexa Multimodal Skills Challenge

Amazon has been rolling out new Alexa features all year. In-skill purchases & subscriptions? Check! New APIs for music skills & hosted skills? Check! A ton of new devices? You know it!

They've also been working on new tools like the Alexa Presentation Language (APL), which enables you to build visually-rich Skills for devices with screens.

Join our latest Alexa Challenge and build a new skill incorporating APL that delivers a multi-modal (voice & visuals) user experience.

There are $150,000 in prizes, with special awards for the best living room, kitchen, bedtime, morning, kids, and in-skill purchasing expriences.


Twitch AWS Extensions Challenge

First, Twitch turned the live streaming world upside down. Now they’re partnering with AWS to elevate the streaming experience with Twitch Extensions.

Extensions are apps that can interact with live streams as a panel on a channel or a video overlay, creating a fully interactive experience between content creators & their viewers.

Get your hands dirty and build your first Extension using the WYSIWYG Twitch Extensions Sandbox. Then, distribute it on the Twitch Developer Portal for a chance to win $26,500 in prizes.


Mobi Grand Challenge

The MOBI Grand Challenge's goal is to create a viable, decentralized, ad-hoc network of blockchain / dlt connected vehicles and infrastructure that can coordinate, share data, and improve urban mobility.

Winning teams will demonstrate how blockchains and related technologies: distributed ledgers, cryptography, tokens, and consensus mechanisms can make getting from A to B safer, cleaner, faster, more efficient and accessible.

There are over $100,000 in prizes sponsored by Ocean Protocol.


Amazon Sumerian AR/VR Challenge

3D experiences are here, and Amazon Sumerian is the quickest and easiest way to build one! Amazon is challenging you to create AR, VR, or 3D apps using their browser-based IDE. Sumerian’s unmatched ease-of-use, you can build highly immersive and interactive scenes for a variety of headsets, and both iOS and Android devices. Plus, with one-click publishing, there's no need to build for each platform from scratch.
