Time for Your Judge's Wig!

Nov 09, 2015

The judging portion of the 2015 Rails Rumble has officially started! Remember, the Rails Rumble is a community judged event. If you completed an app, you’re a judge and you’ll determine this year’s winners! So take some time this week (judging closes on November 15th at 23:59 UTC) to browse through the completed entries and pick your favorites.

When you’re done finding the ones you like the best, go to your favorites section and get it down to your top ten, put them in order, and click the finalize button to lock in your picks!

After you and the other competitors pick their favorites this week, winners will be announced on November 16th. Additionally, after the winners are announced, your team’s accumulated points will be displayed privately to you in your team’s dashboard, if you’re interested in seeing that.

If you want more details about how entries are sorted, how judging works, what kinds of things to look for, and how points for awards are calculated, please check out this very detailed page we put together.

The only award not picked by you is the Public Favorite award and that’s determined by, well, the public! So spread the word about not only your entry, but the whole Rails Rumble. Anyone can come to the site, sign in with Twitter, and pick their favorites.

Lastly, we urge you to leave feedback for other competitors. What did you love about their app? What didn’t you love? How can they make it better? How brilliant was their app? Competitors love feedback, so send it their way!


The Belt.

Oct 28, 2015

Beyond money, beyond notoriety, beyond all the free service prizes, there’s one thing that every single person that competes in the Rails Rumble, wants more than anything.

The Belt.

It’s all about The Belt! This year, our belt sponsor is the one and only Twilio. They’ve been sponsoring us for years now and we’re really happy to highlight their service here for you.

What is Twilio?

If you don’t know what Twilio is, we can explain it very simply. They are the telcom API champion! Developers use Twilio to build complex communication systems. But they’re also easy enough to use on a whim, to build small apps. They’re the perfect service for the Rumble. For instance, 2 years ago Caller Key won the Rumble, and they used Twilio.

What do I do with The Belt when I win?

Pfft, you mean if you win. Stakes is High! Well, if you win, you could wear The Belt at your desk, and show people what’s up.

You could also just sit it on your work fridge, and show people what’s up.

Wait, I thought I heard about Gloves last year?

That’s right! Starting two years back, the solo winners also got a pair of sweet, sweet boxing gloves!

Again, big thanks to Twilio for sponsoring this year’s belt and gloves!

Registration Has Opened!

Oct 26, 2015

The Rails Rumble is a distributed programming competition where teams of one to four people, from all over the world, have 48 hours to build an amazing web app, with Ruby on Rails, or another Rack-based Ruby web framework, along with other web technologies. After the 48 hours are up, everyone picks their favorites and the top ten winners are revealed!

As many have already noticed, registration for the 2015 Rails Rumble is now open! To reserve a spot for your team, just visit and click the big Sign in with Heroku button. After signing in, you’ll be able to register a team, thus reserving a spot in the most action packed weekend of typing into a text editor since last year’s Rails Rumble! After reserving a spot, you’ll be able to invite up to three others to join you on your team.

If you’re in search for others to join your team, or a team to join yourself, use the hashtag #rumbleteamvacancy on Twitter or visit our community Slackline (see below).

There are a few things you should keep in mind:

  • Spots are limited. Reserve a spot for your team early so that you don’t miss out. You’ll be able to add and remove people from your team up until the competition starts.

  • People judging can’t sign up for hundreds of Rails Rumble entries, whether it’s by email or via Twitter. It’s important to remember this when designing your entry. The easier it is to try, the happier the judges will be. It’s proven. It’s science! If you need user accounts, employ a Guest User Record style system.

  • If you reserve a spot for a team and later want to join a different team, realize you’re unable to compete, or just want to change teams, go to, sign in with Heroku, click the account button on the top left, click Team Dashboard, then click the Leave link next to your name under the Team Members section. If you’re the last member of the team, your team will be deleted and your spot will become available for another team that will no doubt be eternally grateful to their anonymous patron.

  • If you aren’t already, get familiar with Heroku before the competition! Here’s a great place to start.

  • To keep up to date with everything Rails Rumble leading up to the competition and during the competition, you should follow @railsrumble on Twitter.

  • To hang out with other rumblers before, during, and after the competition, connect your teams private Slack with our shared, community #rails-rumble Slack channel, powered by Slackline.

  • And speaking of our shared chat, please be sure to read our official Code of Conduct. The Rails Rumble has and will always be a place for everyone. Don’t screw it up.

  • Help spread the word about this year’s Rails Rumble! Take to Twitter and let everyone know that you’ve registered and are ready to show them what you’ve got.

If you need help with anything or have any questions at all, please feel free to contact the organizers. Otherwise, the competition starts on November 7th at 00:00:00 UTC, so don’t be late! We’ll be emailing you a few hours before the competition with more details about your Heroku app and optional GitHub repository.

And finally, while the Rails Rumble is a competition, it’s also about the Ruby community. Be nice. Make friends. Build something you’re proud of. And of course, have fun.

Heroku Add-ons FTW

Oct 22, 2015

As you know, we’ve partnered up with Heroku as our infrastructure sponsor again this year. But what you might not have realized is that you’ll be able to leverage a ton of Heroku Add-ons in your app! Most add-ons have a free tier, but, like last year, Heroku wanted to give you access to even more, so they’ll be making the first paid tier free for a number of add-ons (see below) during the competition.

Once the competition starts, you’ll be able to install these Heroku sponsored add-ons, right from your team’s dashboard here on It’ll look something like this:

And the list is pretty incredible!

Don’t forget, registration opens on the 26th!

IRC Out; Slackline In

Oct 09, 2015

Over the past couple of years, we’ve seen teams using their own chat rooms, more and more, during the competition. So, we’re really excited to announce that this year, we’re replacing our official IRC channel, with a free Slackline community channel!

Okay, but what is Slackline?

Slackline is a service that allows you to collaborate seamlessly with other Slack teams. It saves you time and energy when working with others, by giving you the ability to connect different Slack teams together in private, shared channels.

Say you’re a design shop of three, using Slack to communicate with your coworkers, and you’re working on a project for a company that also uses Slack. With Slackline, you can create a private shared channel, alongside your team’s regular Slack channels, where your two Slack teams can communicate.

How will the Rails Rumble use Slackline?

In addition to creating private shared channels, Slackline also hosts a number of free, public, community channels. And this year, they’re hosting a brand new, official #rails-rumble community channel. So, instead of individuals joining our old IRC channel, and not having a great way to speak with teammates during the competition, you can simply create your own free team on Slack, and connect it to our new free community Slackline channel!

When you speak in your team’s #general channel, it’s private, just like normal, and just for your team. And when you go into the #rails-rumble community channel, you’ll be able to chat with other teams that have connected their Slacks, as well as the Rumble organizers (unless we’re asleep, because we get to do that).

A big thanks to Slackline for hosting our free community chat for this year’s competition, we think it’s going to be great!

Oh, and the community #rails-rumble channel is already up and running, so feel free to connect your Rails Rumble team’s Slack, whenever you have it.

Announcing Rails Rumble 2015!

Aug 11, 2015

After the success of last year’s Rails Rumble, we’re extremely happy to welcome back the one and only Heroku!

The 2015 Rails Rumble will take place on the weekend of November 7th & 8th.

  • Registration: Oct. 26th - Nov. 4th
  • Competition: Nov. 7th - Nov. 8th


Every year we get questions about using other technologies, in addition to Ruby, in your entry, so we just wanted to take a brief moment and expand on this. Despite our name, the Rails Rumble is a hackathon for apps built, at least partially, with Ruby. You may be using Rails, Sinatra, or another Rack-based Ruby web framework for both the front and backend. On the other hand, you may build the entire backend API of your app with Rails, and your frontend with Ember.js, Backbone.js, or AngularJS! Either way, we don’t discriminate!


If you aren’t familiar with Heroku, they provide services and tools that let you focus on building apps, without worrying about infrastructure. You can have your app deployed in minutes and easily scale it to support millions of users. Give them a try by heading over to their site and creating a free account.

Heroku Add-Ons & Sponsors

After hearing from so many competitors about how they loved the ease of integrated Heroku add-ons last year, many of our sponsors again this year will be available during the competition, free of charge, using Heroku’s ridiculously powerful add-on system.

Over the coming months, we’ll be announcing even more sponsors, in addition to Heroku, so if you have a product or service that’d you’d like smart, young, intelligent, thoughtful, developers and designers, from around the world to check out, please let us know.


Because of another success of last year’s competition, our judging revamp, we’re very happy to announce that judging for this year’s Rumble will be once again in the hands of the community. If you ship an app, you’ll be considered a judge!

Furthermore, each team will again see exactly how many points they received, privately in their team’s dashboard, while points for winning teams will be displayed publicly.

Job Board

The last thing we’d like to mention is the Rails Rumble Job Board is back again. If have an opening, and want to support the Rails Rumble, please consider checking it out.


To stay up to date on everything happening with the rumble, you can follow @railsrumble on Twitter, subscribe to our RSS feed, or sign up for our newsletter.

We’re super excited about bringing back the Rails Rumble for 2015 and can’t wait to see what amazing things you all build on Heroku. See you soon!
