Introducing Fabric mission control

by Meekal Bajaj, Product Manager

Since we launched the Fabric mobile app for developers in February, we’ve been using Fabric’s web dashboard ( to stay on top of how our own app is performing. Many times we found ourselves switching back and forth between different dashboards for our production and dogfood builds. Knowing that many of you monitor a lot more apps every day, we set out to build something that can make this experience completely seamless and empower you to know your apps’ performance easily at any moment.

Today, we’re thrilled to introduce Fabric mission control — the pulse of all your apps on a single, intuitive dashboard.

One stop to keep up with all your apps

When key information about your apps lives across different dashboards, it’s hard for the team to have the context they need to make the best decisions. While Fabric today gives you the #1 crash reporting and mobile analytics tools that show you the pulse of your apps, those insights live on different dashboards on We wanted to take that experience to a whole new level.

With Fabric mission control, we bring together the critical top level information across all your apps onto one single dashboard. Now, you get a complete view to easily see the pulse of your apps at a glance.

We’ll be rolling out access and enabling the mission control dashboard for all customers over the next few days. Once it’s enabled on your account, it will automatically be set as your default starting page when visiting You can easily toggle mission control on and off to chose the dashboard experience that works best for you.

From our friends at BuzzFeed:

Fabric’s new mission control is the first thing we look at everyday. We have it up on the TVs at our office so we can monitor our DAU, crash rate etc. across all of our key apps at any given moment.


Data that truly matters — front and center

It’s important to stay on top of the most critical issues affecting your apps. Fabric sifts through millions of issues and events every day and brings you the most important information about your apps. We’ve distilled all that data on your mission control so you can hone in on the areas that need your attention right now.

On your new mission control, you can jump straight to critical issues or see a summary of how your top build is performing. If you’re wondering how well-tested your latest beta is, you can see that as soon as you open your web dashboard.

Key apps and data points —instantly accessible

Fabric lets you decide which apps you want to focus on, and in which order on mission control. Simply favorite an app to pin it to the top or reorder your apps so that the most important ones are the first you see. 

You can also easily locate an app or a number of apps via the search bar built right into your mission control. When searching, we filter the list in real-time to only show the apps that match what you are looking for. Clicking on each metric takes you directly to the details you need.

We couldn’t be happier to get this into your hands. We truly believe that the new Fabric mission control is yet another huge step toward our mission to help you build the best apps. Sign into and check out the new mission control!

New milestone achieved: over 2 billion active devices

By Rich Paret, General Manager, Developer Platform

Ever since we launched Crashlytics four years ago, our mission has always been and remains the same: to build tools that mobile app development teams love. That’s why we built Fabric, which reached a huge milestone last July by serving over one billion active devices around the globe.

Today, just nine months after reaching our first milestone, we’re proud to share that we’ve doubled our previous achievement: Fabric is now serving over two billion active devicesmeasured on a 30-day basis — on both iOS and Android.

It’s been an amazing journey to see Fabric being used and trusted by tens of thousands of top apps around the world. Thank you for trusting your business to Fabric and Twitter; we take that commitment seriously and look forward to continue supporting you in building the best experiences for your customers. Let’s put a dent in the universe together.


Introducing Velocity Alerts

by Jason St. Pierre, Product Manager

Since the birth of Crashlytics, our passion has always been to help you fix the most prevalent issues quickly and painlessly. Just last month, we released badges to help you hone in on crashes that stand out against the rest.

Today, we’re thrilled to introduce Velocity Alerts: intelligent, proactive alerting on the most critical issues happening in your app. Now, you truly know when you need to take action right away.

Powered by the #1 mobile analytics solution

While our system already distills and prioritizes your crashes based on their impact, there was more we could do to make your life even easier. By combining your app’s crash data with usage analytics from Answers, our new Velocity Alerts enable you to triage unexpected, high-impact issues with minimal effort.

Now, once you’ve enabled Answers as part of Crashlytics, our system will proactively check to see if there is a statistically significant number of sessions that have ended due to a crash related to one issue on a particular build. If so, we'll let you know if that issue is a hot patch candidate and needs your attention immediately right on your dashboard. You’ll also get an email alert in your inbox as well as a push notification if you’re using the Fabric mobile app(Android support coming soon). With Crashlytics, you’ll never miss a critical bug!

While at it, we’ve also redesigned all of our notification emails so important information are even more clear and actionable.

We couldn’t be happier to release this so you can sit back, relax and just focus on building the best app. If you’re already using Crashlytics with Answers, Velocity Alerts are automatically enabled for you. If not, get started with Answers!

Introducing screengrab: automating screenshots on Android

By Hemal Shah, Product Manager

When Fabric partnered with fastlane four months ago, our goal was to give you the best deployment tools for your mobile apps. Since Twitter Flight, we’ve been making fastlane and its beta support for Android even more powerful.

Today, we're thrilled to share that we're introducing screengrab for automating screenshots on Android!

Automated, seamless, in your language of choice

A picture is worth a thousand words. Your screenshots need to reflect the best of your app's user experience, but taking perfect screenshots is a ton of work. The process includes capturing the shots, making sure each one is lined up correctly, and then localizing them for your customers’ needs. With screengrab, taking and uploading screenshots to the Google Play Store has never been easier.

Screengrab is entirely automated from the command line.


We’ve even made localizing your screenshots much simpler. By launching your app in multiple languages, screengrab allows you to verify that your localizations fit into labels on all screen dimensions in minutes.

Sitting on top of existing UI tests, screengrab connects with the rest of the fastlane toolset, streamlining the entire deployment process. You can prepare screenshots and then submit them to the Google Play Store with the rest of your app using supply.  Since screengrab is tightly integrated with fastlane, it’s super simple to integrate it into your existing workflow.

Set up once, run everywhere

Remember the last time you created screenshots for your app? It might have been as a preview to see what a recent change you made looks like, or for the design team for their latest mockup. Those tasks take time and energy away from what you really want to do: build awesome stuff. Setting up screengrab ensures no duplicate work is being done by your team. You can also stop putting the responsibility on one person who "just knows what to do." Once you've set up screengrab and checked in your config file, anyone on your team can generate screenshots with no additional steps required.

We built screengrab to give you your time back, making release day that much better. As an open source tool, we are excited to work with the community to build on this initial foundation and continually grow this tool!                                              

Appsee and Mapbox Kits Now Available on Fabric

By Jonathan Zazove, Product Manager

Update: Fabric has deprecated the third party kits as of August 2, 2018. See our help doc to learn more.

A little over a month ago, we introduced eight new partners to the Fabric toolset to help you solve key challenges within mobile development. We started out with installable kits for the Amazon, Stripe, and Optimizely SDKs. Since then, we've been working closely with the rest of the partners to build out their kits on Fabric:

As before, we want to give you access to the best-in-class developer tools without the typical frustrations that come with adopting new mobile SDKs. And today, we're thrilled that two more partners, Appsee and Mapbox, have made their kits available on Fabric!

The best-in-class tools at your service

With the Appsee and Mapbox kits, we believe each one brings immense value to developers using Fabric.

Appsee: Building an exceptional user experience requires both in-depth qualitative and quantitative understanding of your customers’ behavior. With Appsee's experience analysis platform, you can see exactly how people are using your apps with features like user recordings and touch heatmaps. Learn more about Appsee here.

Mapbox: Mobile has made geolocation and maps crucial to app customer experience, and implementing maps into your apps should be simple. Mapbox gives you the building blocks that make it easy to integrate location into any mobile app. Their Studio design suite allows you to design and style beautiful maps and satellite images. Learn more about Mapbox here.

Seamless installation

As with our Amazon, Stripe, and Optimizely kits, we'll automatically provision your keys so you can easily onboard your app if you already have accounts with Appsee or Mapbox. You can also install or update those SDKs with a simple click on Fabric.

When we release the rest of the partners’ (GameAnalytics, PubNub, and Nuance) kits in the coming weeks, we’ll update this post to let you know. Stay tuned!
