Who uses ReactiveX

[staltz]

On the frontpage, I'm planning to include a section "Who uses Rx" listing a few companies that use Rx in a significant way or as a core technology. My memory is very bad at the moment and honestly I can just think of Netflix and Couchbase.

So, could you guys list a few more so I can fill this list?

UPDATE:

If you wish to have your companies' logo and link on the frontpage, just provide a png image of size approx. 500x200 (or better), with white or transparent background, and a link to the page. We can include logos as much as there is incoming, but at some amount (maybe 12?), we should reconsider which ones are stronger for social proof.

Logos will be sorted by decreasing Alexa ranking (global), and with a max of 12 logos on the frontpage. Current sorting as of 19 September 2014:

1. Microsoft (42)
2. Netflix (81)
3. GitHub (133)
4. SoundCloud (180)
5. Trello (531)
6. Treehouse (2,224)
7. SeatGeek (14,258)
8. ooVoo (24,278)
9. Couchbase (49,285)
10. Futurice (385,110)
11. Welbe (1,573,204)

The GitHub app uses RxJava. Soundcloud also uses it. Rx.NET ships on every windows phones and Cortana (Siri competitor) is completely built on Rx. There's more but my memory is also lacking at the moment :)

Ok, I'll gather some 'evidences':

• Microsoft Cortana: http://channel9.msdn.com/events/TechDays/Techdays-2014-the-Netherlands/Event-processing-at-all-scales-with-Reactive-Extensions
• Soundcloud: https://developers.soundcloud.com/blog/hassle-free-concurrency-in-android-using-rxjava
• Netflix: http://techblog.netflix.com/2013/02/rxjava-netflix-api.html
• Couchbase: http://blog.couchbase.com/why-couchbase-chose-rxjava-new-java-sdk
• Futurice: http://blog.futurice.com/top-7-tips-for-rxjava-on-android
• ... ?

@GeorgiKhomeriki I don't think any official GitHub apps use RxJava atm (though that's solely because we don't really use Java a lot here).

Rx.NET is used in almost every C# project we write including GitHub for Windows, and GitHub for Mac uses ReactiveCocoa. The Atom project is also planning to use RxJS though they're currently in an API freeze and want to save that change for vNext.

@paulcbetts Thank you for clearing that up.

[dlew]

I am a Trello Android developer and can confirm that we're using it quite a bit. We're getting more and more reliant on it each month. :)

[wilka]

We use the .NET flavour of Rx and ReactiveUI in our Progenesis mass spectrometry products at Nonlinear Dynamics (as well as most of our internal tools).

[Takhion]

At Clue we're developing the Android version of the app using a lot of RxJava!

[srvaroa]

Hi, at Midokura we're using it for our distributed network virtualisation solution (Midonet). It's already being used for components that deliver part of the network configuration and state, we're currently working to extending these usages.

[experquisite]

I am evaluating RxScala for some financial trading applications.

[staltz]

Hi @dlew , @WilkaH , @Takhion and @srvaroa , if you wish to have your companies' logo and link on the frontpage, just provide an png image of size approx. 500x200 (or better), with white or transparent background, and a link to the page.

[hamidp]

@staltz For Trello, there are logos on https://trello.com/about/branding

If you need a specific size or format let me know and I'll get them over

[staltz]

That will do. ;)

PS: I'll include logos/links as much as there is incoming, but at some amount (maybe 16), we should reconsider which ones are stronger for social proof.

[mwadams]

We http://endjin.com use Rx (.NET) in our core IP. It is in use with a bunch of clients including http://recruitmentgenius.com

[jwooley]

I've used Rx.Net in a number of customer internal apps, so I can't name the companies. One public one I can divulge is that I did include it in my small phone app - Metronomicon. http://www.windowsphone.com/en-us/store/app/metronomicon/45455fdc-e60f-47e4-8a5a-68710d665cd1

[tamirdresher]

ooVoo for windows phone 8 uses RX http://www.windowsphone.com/en-us/store/app/oovoo-video-call/7b7772c6-3fe6-4dc1-a6cf-b611777a9781

And in almost every project i was consulting, we used RX

[dallasgutauckis]

Android dev for SeatGeek here; we're using RxJava in our latest version. Absolutely love it.

• Here's our marketing imagery for logo usage: https://seatgeek.com/press

[anaisbetts]

@staltz probably want to grab double that size for Retina / HiDPI

[staltz]

It's already doubled. ;)

[Yarikx]

We use RxJava a lot in Attendify for our Android App.

[AndrewReitz]

Android Developer @ SmartThings and I can confirm we use RxJava.

[dbrattli]

Microsoft Delve uses RxJS. http://blogs.office.com/2014/03/11/introducing-codename-oslo-and-the-office-graph/

[noseratio]

I use Rx .NET to properly react upon different sequences of user input events inside an editing component. It's much easier than implementing a complex state tracker.

[gavrix]

Qwyrk iOS app is built on RAC. Android version is partially using RxJava (moving to RxJava in future).

[daschl]

Couchbase uses RxJava for its new JVM SDK, but I was very glad to see you already put our logo on the front page, thanks!

[badamczewski]

Monitoring system for a bank (that shall remain nameless) uses Rx for .NET to capture and analyse incoming streams of events from various systems.

[dbrattli]

Microsoft uses RxJS for Onedrive Business. https://onedrive.live.com/about/en-us/business/

[glennblock]

We use RX in our new Splunk C# SDK. I blogged about why we chose it here. Splunk's SDK allows doing realtime queries which continually stream events i.e. a push model. In particular it's helpful for building responsive UIs pulling Splunk data.

[glennblock]

I can email a logo, just give me an email to send to.

[mattpodwysocki]

@glennblock wait, you use JS in your C# SDK?

[glennblock]

@mattpodwysocki no .NET. Did I say JS?

[glennblock]

@mattpodwysocki yes I did. :-). Edited

[glennblock]

Forgot to mention, we also have this page in our docs which talks specifically about Rx.

[austynmahoney]

We use RxJava on Android at O.C. Tanner and Welbe in our Android app

[joesteele]

We at Treehouse use RxJava extensively in our new Android app

[tkowalcz]

Hi,

we at codewise.com use RxJava in our real time analytics product voluum.com (I mention the product only because it has significant traffic as opposed to company webpage).

[Takhion]

At Clue we're developing the Android version of the app using a lot of RxJava!

[tonycosentini]

@staltz are you still accepting logo submissions via this thread (assuming the company is in top 12 Alexa ranking)?

[DavidMGross]

Do you want to keep this issue open as a way of accepting new submissions, or can we close it as resolved?

[devxoul]

StyleShare uses RxSwift and RxJava for apps.

[LanaIV]

Hello, I'd like to use Rx logo to create meetup presentation image: https://www.meetup.com/Reactive-Paris/. Can I use it without any legal issues or where can I ask authorization to use it. Thanks in advance.

[akarnokd]

Might not be relevant after so much time. If still, please open a new issue.
