Level up your workflow with these new Marketplace Apps


We're welcoming four new apps to GitHub Marketplace—built to help you review, secure, and monitor your code.

Code review

AccessLint brings automated web accessibility testing into your development workflow. When a pull request is opened, AccessLint reviews the changes and comments with any new accessibility issues, giving you quick, timely, and targeted feedback, before your code goes live.

Dependency management

Dependabot helps you keep your Ruby, JavaScript, Python, and PHP dependencies up-to-date. Every day, Dependabot pulls down your dependency files and looks for any outdated requirements. If dependencies are out-of-date, it opens individual pull requests so they can be updated.

Greenkeeper brings safety and consistency to npm with real-time monitoring and automatic update testing for your dependencies. It acts as a friendly bot that sends you informative, actionable pull requests and issues so you can easily keep your software up-to-date and in working condition.


LogRocket lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen or asking users for screenshots and logs, LogRocket provides you with a video recording of exactly what the user saw, along with console logs, network requests, and application states so you can quickly pinpoint what went wrong.

We’re excited to keep giving developers the tools they need to build software and the flexibility to evolve their workflows as their needs change. Discover new tools on GitHub Marketplace and integrate them into your workflow in minutes.

GitHub now works directly with AWS CodeStar

GitHub and AWS

From code review and project management to deployment and monitoring, you can choose the exact tools your workflow needs among hundreds of apps and services available on the GitHub platform.

Now it’s easier to connect GitHub to your deployment system of choice with AWS CodeStar's new integration. Use GitHub directly within AWS CodeStar’s continuous integration and continuous deployment (CI/CD) toolchains, and manage your software release workflow including code commits, builds, and deployments for AWS applications in one place.

Each AWS CodeStar project template provides you with the option to use GitHub as your version control system for the software projects you build with AWS.

GitHub in AWS interface

When you create a new project with AWS CodeStar and GitHub, you’ll also be able to centrally track commits, issues, and pull requests from a single dashboard—making it easy to manage project activity across your CI/CD toolchain and simplify project management for your AWS applications.

AWS and GitHub integration

Start building with GitHub and AWS CodeStar today. And stay tuned for more integrations that bring together your favorite software development tools.

Project note summary cards bring more context into your boards

Now you can get a more complete overview of the work going into your project without leaving your project board. When you reference an issue or pull request in a note, you'll see a preview of the cross-referenced link in a summary card.

Example of project summary cards

Projects are a great way to organize tasks, but often those tasks have external dependencies to keep track of. Notes provide a way to add links to those external dependencies. Now, those references will bring valuable context like assignee, state, and labels right into view on the board.

You can add any issue or pull request on GitHub to your project by entering its URL into the note field. If it can be a first class card in the project, we'll convert it for you. If it's outside the scope of your project, you'll see the new summary card instead. This behavior is automatically applied to all notes, so there's nothing you need to do to upgrade your existing boards.

Inline comments in GitHub for Visual Studio

GitHub for Visual Studio 2.3 adds the ability to comment on pull requests directly from your IDE. Simply open a pull request in the GitHub pane in Visual Studio, and open a compare view, and you'll see existing comments right there in the editor. Click the icon in the margin to add new comments.

Inline comments using without leaving your IDE

The functionality is limited right now to adding single comments, but we're hoping to bring the whole GitHub review experience right into Visual Studio soon!

On top of that, we've shipped a whole bunch of new features and bugfixes. To find out more check out the release notes.

Announcing GitHub Desktop 1.0

Collaborating on GitHub with the power of a GUI application just got easier! GitHub Desktop 1.0 is now available.


A few months ago, we completely redesigned and reimplemented GitHub Desktop on Electron to provide a simpler, more unified experience. The public beta launched in May. Since then we've been hard at work fixing bugs, adding features, and responding to feedback—but now we're ready for prime time. Here's an overview of what you'll see in 1.0.

Image diffs

Image diff example

Easily compare changed images. See the before and after, swipe or fade between the two, or look at just the changed parts.

@mathieudutour implemented image diffs for Kactus, a design review tool forked off GitHub Desktop. Then he was kind enough to submit the work back upstream to us!

Faster cloning

Clone dialog

See all your repositories and clone them with the click of a button. Git LFS assets download in parallel for even faster cloning.


Editors and terminals

Open your favorite editor or shell from the app, or jump back to GitHub Desktop from your shell. GitHub Desktop is your springboard for work.


GitHub Desktop works with GitHub Enterprise. Log in to your GitHub Enterprise server, clone, commit, push, and pull. Whether you're working on a personal or company project, GitHub Desktop is here to help.

Open source

GitHub Desktop is open source and we've already received some fantastic contributions from the community. Go check out our roadmap, contribute, and help us make collaboration even easier.

Classic apps

We think GitHub Desktop is a big step forward—but don't worry, we won't force you to update! If you have a good thing going with the classic Mac or Windows app, you can continue to use them and move over to the new app when you're ready.

Project navigation for the way you work

Today we shipped accessibility enhancements to GitHub Projects that make it easier for everyone to navigate and update their project boards. If you rely on assistive technology or prefer using the keyboard to get work done, you can now use these tools more effectively to manage your projects on GitHub.


With new keyboard shortcuts, you can efficiently move and navigate between cards and columns. Select a card or column using the enter key and move it anywhere
on the board. Commit the change with enter again, or cancel it with escape. Press the ? key on any project board to review the new keyboard shortcuts in more detail.

We're committed to building tools that empower everyone to work better together. The changes we're announcing today are a first step toward more accessible project management on GitHub. We'd love to hear from you about other ways we can help you do your best work.

Introducing Atom-IDE

Atom IDE

In collaboration with Facebook, we're excited to announce Atom-IDE—a set of optional packages that bring IDE-like functionality to Atom. The initial release includes smarter, context-aware auto-completion, navigation features, like outline view and goto-definition, and other useful functions, errors, warnings, and document formatting.

Learn more from the Atom Blog

A look at Atom-IDE

Atom-IDE includes packages for C#, Flow, Java, JavaScript, PHP, and TypeScript that use the power of language servers to provide deep syntactical analysis of your code and projects—but this is just the start of our journey. With the help of our community, we plan to expand the number of languages that Atom-IDE can support and make it possible for you to run and edit applications, making Atom-IDE a true IDE.

Check out our post on the Atom Blog to get started—or to learn how to create an Atom-IDE package for your favorite language.

Release Radar · September 2017

Release Radar September 2017

Welcome to the first edition of the Release Radar, where we share the projects popping up on our radar—from world-changing technologies to weekend side projects. Most importantly, they're all projects shipped by you. Hopefully, we'll find little something for everybody: a new app for your tool belt, a fresh experiment for your free time, or a game to play with on your next coffee break.

This month we’re sharing projects to make your data sizzle 🔥 and add animations to your native apps with ease. Enjoy!

Lottie for iOS 2.0.0

Lottie is an Android, iOS, and React Native library that renders After Effects animations in real time, allowing developers to add animations to native apps just as easily as static assets.

Lottie started as a hackathon project at Airbnb, but @buba447, @therealsalih and @gpeal from the Airbnb Design Team have continued to iterate on it. View the Lottie for iOS 2.0.0 release notes.

Animations created with Lottie

Did you know: Lottie was originally named Lotte after Charlotte Reiniger—an original trailblazer of animation. She made one of the first feature-length animated films, and her work still holds up today.

FlameGraph 1.0

Visualize profiled software with FlameGraph to identify your most frequent code-paths quickly and accurately. The team tagged the 1.0 release to allow package maintainers to grab static versions, but don't let that fool you. FlameGraph has been around for years—and has likely improved performance for products and services you use every day.

"It confuses people at first since the x-axis is not the passage of time; it's an alphabetical sort. People move from 'I don't like it, it's not intuitive' to 'This is amazing, how did I ever live without it?' quickly". - @brendangregg

Mixed-mode FlameGraph spanning kernel and user code

Did you know: Brendan coded the first version of FlameGraph in a single night; he didn't think he could play around with new visualizations at his day job when there were more pressing deliverables. The next day, he used it for work to understand the difference between two massive MySQL profiles that were thousands of pages of text each.

Drupal Console 1.0.0

Drupal Console is a command line interface for Drupal. Add users, debug issues, generate boilerplate code, and more. Version 1.0.0 was just released at Drupal Camp Costa Rica—the largest web development event in the country.

“It’s amazing how a project we started a few years ago as a Drupal 8 learning exercise is now considered for the Drupal community a must-have tool to accelerate Drupal 8 development.” - @jmolivas

Drupal Console terminal output

Did you know: Drupal Console is hitting all the right milestones lately. Last month, they celebrated one million downloads. Congratulations, all around!

Redash 2.0

Redash is an open source tool for teams to query, visualize, and collaborate on data from MySQL, Graphite, Presto, BigQuery, Redshift, and many other data sources. No more exporting data into Excel or spending weeks building dashboards.

Refer to the release notes for some highlights and contributions from the community.

Example Redash data visualizations on

STF 3.0

Smartphone Test Farm (STF) is an open source web application for controlling and debugging smartphones and other devices—right from the comfort of your browser. Testing your latest app or game on all devices has never been easier.

View the 3.0.0 release notes

Animation showing STF's capabilities

Did you know: STF's origins lie at CyberAgent in Tokyo, where it was used to control over 150 devices.

react-map-gl 3.0

react-map-gl is a suite of React components for Mapbox GL JS, a JavaScript library that uses WebGL to render interactive maps. You don't need to have as much data as Uber to create beautiful data visualizations.

View the v3.0.0 release notes

Example showing react-map-gl's dynamic styling

Did you know: This is just one of many frameworks created and maintained by the Visualization Team at Uber. Read more about the entire framework

Starcraft II API v1

The Starcraft II Development Team just announced the release of the Starcraft II API for gamers and researchers advancing the field of Artificial Intelligence (AI). In addition to sample code and bots, they've also included a dataset of replay data from some of the world’s best Starcraft players.

Did you know: There's an Annual Starcraft AI Competition, where researchers compete annually with bots, using the the open source Brood War Application Programming Interface (BWAPI) C++ framework. Interested? You can fork a sample bot called UAlbertaBot.

PySC2 1.0

In partnership with Blizzard, Deepmind also released PySC2—a Python wrapper for the new API for reinforcement learning agents to interact with the game. They also share some mini games (which they think of as more of unit tests). In these, agents achieve a level of play comparable to a human player—moving to beacons, building marines, and more.

Simple RL mini-games allowing AI researchers to test the performance of RL agents on key tasks

Did you know: Although bots are currently no match for a human, we might see a bot defeat the world's best human players in the next few years. Learn more

Lumberyard 1.10

Lumberyard, Amazon's AAA game engine integrated with GameLift and Twitch just released 1.10 with over 500 new features, bug fixes, and performance improvements. They also made the source code available, so game developers can customize and optimize the code to suit their needs.

.NET Core 2.0

Finally, our friends at the .NET Foundation released .NET Core 2.0—a lightweight, modular platform for creating web applications and services that run on Windows, Linux, and Mac. Learn more from Scott Hunter and members of the .NET Team on Microsoft's Channel 9.

.NET Core 2.0 discussions on Microsoft's Channel 9

Did you know: Microsoft also released ASP.NET Core 2.0, Entity Framework Core 2.0, and the complete .NET Standard 2.0 specification—not a surprise considering Microsoft had the most open source contributors of any organization last year.

This is just a sample of all the awesome things you shipped last month. Are you releasing something exciting soon? We'd love to help you celebrate! Send a note to releaseradar@github.com

Quickly review changed functions in your Python pull requests

Last month, we released a new way to quickly review pull requests by listing the changed functions or methods in the pull request file finder. Now Python enthusiasts can quickly identify changed functions in their pull requests, too.


Searching the file finder for the term function or the name of a changed function in a Python file will provide you with a timeline-style view of the results, so you can easily identify and view the most impactful parts of a pull request. Check out the documentation to learn more.

We hope this helps make more of the review process for the Python community more efficient. Let us know if you have any feedback—or if there are other search functions you'd find useful using our help form.

GitHub Classroom now supports deadlines and class rosters

Nathaniel Woodthorpe spent his summer as an Engineering Intern working on GitHub Classroom alongside the Education Team. In this post, he'll share the features and updates he worked on for thousands of teachers and students.

Updates to GitHub Classroom

Teachers can now use GitHub Classroom to set deadlines, track student accounts, and more. Here’s how to use these features in your course and set them up for the first day of class.

Insight into student progress with deadlines

Track student progress leading up to a due date with assignment deadlines. Deadlines fetch the latest commit SHA on the default branch at the time of the deadline, and displays this to the teacher as a “submission”.

View student submissions

If students try to modify previous work, they'll also modify this SHA on GitHub. The submission SHA professors have will then become invalid, alerting them to the changes.

Want students to keep working for partial credit? In this solution, students can work after a deadline. Adding commits on top of an SHA doesn't modify its base.

Easier course set up with Classroom rosters

Classroom rosters provide teachers with a snapshot of course activity at a high level, and an easier way to connect student names with GitHub usernames.

Add student information to Classroom rosters

When a teacher creates a classroom, they have the option of entering student information—email addresses, student numbers, or any other identifying piece of information.

If they haven't already, students can add their personal or contact information when accepting a Classroom invitation, creating a link between their work and their online identities.

And a few more improvements

In addition to these two features, we've shipped some exciting updates this summer. Classroom now has short URLs for assignment invitations, improved assignment views, DataDog instrumentation, and new performance improvements.

Summer internships at GitHub

At GitHub, I got to help improve Classroom and grew as an engineer in the process. Thanks @johndbritton, @tarebyte, @mozzadrella—and everyone else who mentored and worked closely with me.

In two months, I’ll start at GitHub as a full-time Platform Engineer. Though I'll be on another team, I’ll continue to help shape Classroom into an even better experience for the thousands of students and teachers who use it.

Want to build great things together next summer? Applications are opening soon for summer 2018 internships in engineering, data science, marketing, and more.

Introducing seven new apps to GitHub Marketplace


Whether you’re working on an open source project or building a software company, chances are you can simplify your work with GitHub Apps. In May, we launched GitHub Marketplace—a place where you can easily discover, purchase, and integrate new tools that customize your workflow. Today, we’re launching seven new apps in Marketplace and four new categories: Dependency Management, Localization, Security, and Time Tracking.

Code quality, Code review

Better Code Hub provides development teams with immediate, relevant feedback on code quality. It checks a code base against ten guidelines for maintainable software, delivering actionable recommendations and helping your team get to a shared definition of done. A score of ten out of ten indicates you’re performing among top development teams within the industry.

Code Climate provides automated code review, analyzing every commit, branch, and pull request for complexity, duplication, security, and more. It also combines line-by-line test coverage reports, technical debt assessments, and style checks in every pull request so your team merges only clear, maintainable, and well-tested code.

Coveralls helps teams deliver code confidently by providing test coverage history and statistics to show which parts of your code aren’t covered by your test suite. It works with your CI server to sift through new code and reveal changes in overall coverage. Coveralls can also stop deployments that contain newly untested code to protect your live application.

StyleCI is a PHP coding style service that automatically analyzes the code you push to GitHub. If something is amiss, it will immediately notify you through the GitHub Status integration. You can also configure StyleCI to automatically create a pull request with fixes.

Dependency management, Security

Gemnasium monitors project dependencies and alerts you to updates and security vulnerabilities, providing information about all of your repositories in a single interface.


GitLocalize is a continuous localization tool built for communities and teams that want to simplify their workflow when translating content. GitLocalize automatically syncs with your repository so you can keep your workflow on GitHub. It also keeps you updated on what needs to be translated.

Project management, Time tracking

WakaTime provides you with metrics, insights, and time tracking automatically generated from your programming activity. Compete with your friends on private leaderboards, and improve your productivity with your own personal dashboard.

Whether you’d like to automatically build and test your code as you push it to GitHub, measure performance, track errors, or manage projects, GitHub Apps give you flexibility across your development process. And our ecosystem is always growing. Discover new tools on GitHub Marketplace and start using them in minutes.

Quickly review changed methods and functions in your pull requests

The biggest barrier to code review is often time, but there's a new way to easily understand how changes impact your code. Now you can navigate to changed methods and functions right from your pull request file finder.

Changed methods and functions

Searching the file finder for a method or function in a Go, JavaScript, Ruby, Python, or TypeScript file will provide you with a timeline-style view of the results, so you can skip to the most impactful parts of a pull request. Check out the documentation to learn more.

We hope this helps make your review process even more efficient. Let us know if you have any feedback—or if there are other search functions you'd find useful using our help form.
