Goes live in 

We have great news! Owing to the overwhelming response to the hackathon and to ensure everyone gets a fair chance, we have decided to extend the submission deadline by a full week! The last date for submissions is now 11:55 p.m., 15th October, 2018. So you have a full extra week to refine what you’ve already built or to even build something entirely new, from scratch!

Remember - all it takes is a few hours to build something awesome with the API! So go ahead and build the wackiest, most innovative messaging app you can think of, and win up to ₹50,000 along with other cool goodies!

What is /Code?

Looks like it’s your time to shine. Welcome to /Code – an online hackathon for developers to build quirky messaging apps and innovative chat-based experiences using the Chat API.

This is for all the times when you felt like WhatsApp & Messenger just don’t cut it. For all the times you wanted to build your own version – with a ton of awesome features! With the API, you can build your own messaging app in just a few hours…and win cash rewards totaling ₹50,000 for all that effort…

(…along with more uber-cool stuff! Like glow-in-the-dark tees, backpacks, smartphone accessories, earphones, snazzy stickers, wallets, figurines and other awesome memorabilia.)

The challenge is pretty simple:

Build an impressive messaging app that uses chat innovatively, like:

  • A Slack for educational institutes
  • A WhatsApp for places affected by natural disasters
  • Or even a whole new chat-based social media experience

Add unique chat features, like:

  • Show an ‘Order Pizza NOW!’ button on every message that mentions pizza
  • Allow people to privately reply to each other right within a group chat, so their thumbs don’t get tired switching between channels
  • Let users display Animoji as their profile pic, because that animated alien face just looks nicer
  • Or even set limits for outgoing notifications, so that users don’t get bombarded by a thousand notifications if they’re away for 60 seconds

And if you really have that “crazy scientist vibe,” you could even infuse your chat system with AI-based chatbots, location tracking features and more! You’d think it’s magic, but it’s just

How? Because is an API-first chat platform that allows you to create anything with messaging & chat. In fact, adding new functionalties is easier than spelling ‘fnuctionalities,’ thanks to’s low-level semantics that allow data from third party services to seamlessly flow in and out of your chat system.
