You can review just about anything

Code, documents, artwork, you name it!

There's more to your project than just code. Documentation, artwork, website designs, interface mockups, release announcements, feature specifications, and the list goes on.

  • Image Review

    Mockups, screenshots, and other images

    A picture paints a thousand words, and can be key in a review.

    Drag-and-drop one or more images onto your review request to make them instantly reviewable. Your team will be able to click-and-drag anywhere on the image and leave a comment. When they do, you'll see their comment right along with that portion of the image.

    Made a tweak to the image? Just upload a new revision and view a visual diff of the changes through one of our many image diff modes.

  • Text Review

    Text-based files

    Sometimes you'll have other text content that's not part of your source tree. Log files, sample configuration files for testing, or console output, for example.

    Drag-and-drop them onto your review request, and they'll be reviewable just like source code, complete with syntax highlighting. Comments can be left across multiple lines, and they'll show up along with those lines in reviews.

    Like images, uploading a new revision will even let you diff between them!

  • Markdown Review

    Markdown documents

    Documentation is an important part of most projects.

    Review Board provides review support for Markdown attachments, showing both source and rendered documents so reviewers can see not only the Markdown source, but the rendered document as well.

    You can also diff between versions of a Markdown document, in either source form or rendered form, and comment on any range of lines.

  • PDF Review

    PDF documents

    With the optional Power Pack, PDFs can be attached and reviewed as well. This means you can print any type of document to PDF (Word, Excel, etc.) and review it right within Review Board.

    This is incredibly useful for reviewing product documentation, requirements documents, schematics, presentations, or other types of documents related to your product, right from within Review Board.

  • And, of course, source code

    Review Board's leading diff viewer shows you code in ways others don't, helping you catch problems you might otherwise miss.

    We have a lot to talk about here.

See your code changes in a new light

Our diff viewer catches things that others miss

Diff viewers are central to code review tools. Unfortunately, most do little more than show you what lines changed. Ours goes beyond that to show you how and why.

  • Syntax-highlighted Diffs

    Syntax-highlighted diffs

    See your code in all its glory with syntax highlighting for over 300 languages. This isn't just about looking pretty. This can help you catch reserved keywords, mismatched strings, leftover comments, and more.

  • Indentation in Diffs

    Smarter indentation handling

    When you indent a block of code, most code review tools will just show you a bunch of deleted and inserted lines. If you indent and change your code, your changes just get lost in the noise.

    Review Board doesn't do this. Instead, we show you special markers showing how far each line was indented (or unindented). If the code hasn't changed, we won't waste your time with colors or other noise. If it has, we'll show you that, too!

  • Move Detection in Diffs

    Moved code detection

    Ever move some functions or other code around in a file, and then try to review it? It's a pain! It's hard to tell what code has moved and to where, or whether there were other changes to pay attention to.

    Not here. Review Board checks that for you, helpfully showing where code moved to, from where, and whether there were any other changes made during the move.

  • Diff Function/Class Headers

    Know exactly what function or class you're in

    Review Board understands most major types of source code, and will helpfully show what class or function any change is in, so you'll know exactly where a change is being made.

    See more context in your diffs

    Sometimes changed lines aren't enough. To fully understand what's changed, you need to see more of the function, class, or the file in general.

    Wherever you are in a diff, you can click to expand the diff up to the nearest function/class, or expand 20 lines in any direction. If you really need everything, you can also expand the full contents of all files.

Craft higher-quality reviews

More informative reviews without all the hassle of other tools

Code review takes time, and we want to give you the most value for your time. Through our review capabilities, we help you produce high-quality contextual reviews that better track the defects in code and documents.

  • Multi-line Commenting

    Multi-line commenting in diffs/text files

    Comments aren't always about just one line in a file, but most code review tools only allow you to leave a comment on one line.

    Review Board makes it easy to comment across multiple lines. Just click-and-drag across the range of lines you want to comment on.

    This works for diffs and for text-based file attachments on a review request.

  • Regional Commenting

    Region commenting in images/PDFs

    When reviewing images and PDFs (with Power Pack), you can review any part of the image or document by clicking-and-dragging to leave a selection and typing your comment.

  • Filing an Issue Issue Summaries

    Track issues that need to be addressed

    When leaving a comment, you can mark it as an issue that needs addressing by the owner of the review request. All open issues will be shown as a kind of To Do list, giving the owner a clear list of what needs to be done for their next iteration.

    Comments can be left on anything. Diffs, text files, images, PDFs. They're a great way to tracking what state the code or document is in, and what needs to be done before it can be approved.

  • Reviews

    Organized reviews and discussions

    Every review gets its own box under the review request, containing every comment made across every reviewed diff and file attachment. Discussions around that review are also contained within the review.

    This keeps discussions in one logical place, instead of being scattered across diffs and files.

    Contextual comments in reviews

    Comments made on a diff, image, text file, or document are shown in a review along with the file's content. You can see the lines of the diff or text file or areas of an image or document without leaving the page.

    Need to see more of the commented diff? Simply expand the diff right there in the review! This works just like it does in the diff viewer.

All review requests, all in one place

Not scattered across a bunch of different repository pages

Whether you're using one repository or hundreds, hosted yourself or on another service, you'll be able to find everyone's code reviews in one place: Your Dashboard.

  • Dashboard

    Track what's next using the Dashboard

    Your Dashboard gives you an up-to-the-minute overview of all the review requests you care about. One look and you'll know what's next on your plate.

    View review requests by your subscribed project or team groups. Sort your review requests in any number of ways.

    Switch between everyone's incoming review requests to your outgoing ones to see if you have work to do, or if you're ready to land your changes.

  • Dashboard Inbox Zero

    Keep organized and get to Inbox Zero

    Archive review requests to hide them until there's new activity, to help keep your Dashboard free of clutter. You can archive one at a time, or multiple at once!

    Mute review requests you just don't want to see anymore. They'll be gone from the Dashboard until you want to find them again.

    Focus just on what you want to see, so you can get your job done fast.

  • Customizable Dashboard

    Make it your own with customizable columns

    Everyone works differently. Make the Dashboard your own by choosing exactly what you want to see.

    Pick from a large list of useful columns (bug listings, diff stats, activity indicators, and more), and order them the way they make sense to you.

    Go even further and create custom columns through Review Board's extension framework!


LDAP, Active Directory, and Reports. Oh my!

  • Authentication Methods

    Log in with Active Directory, LDAP, or others

    We work out-of-the-box with your existing authentication servers. Whether you're using Active Directory, LDAP, NIS, or something more specialized like HTTP Digest Authentication or X.509 Public Keys, we have you covered.

    If you need something a bit more specialized, you can write a custom authentication backend with Python to connect to any service you need.

  • Reports

    Track how things are going with Reports

    The best teams and organizations are always looking for ways to be even more efficient, no matter how big or small they are. By getting insight into how your developers are taking advantage of code review, you can develop more cost-effective processes and policies, saving your team time and money.

    With the optional Power Pack, you'll have several powerful ways of looking at how your developers are taking advantage of Review Board. Our at-a-glance graphs will show you who is pulling their weight, how thoroughly code is being reviewed, and more.

  • Access Controls

    Control access to everything

    You have complete control over who can see what. Limit who can look at review requests and source code based on the repository. Create invite-only groups and prevent others from seeing the review requests posted there.

    Need even greater isolation? You can separate your single Review Board install into several independent sites, one for each organization or team, without managing multiple servers.

Highly extensible

Add your own features and integrate with the rest of your tools

Review Board has a fully-featured API and extension framework for hooking into your existing scripts and tools. You can make Review Board do just about anything you want to do.

  • API

    Full REST API

    Review Board's comprehensive REST API provides full access to all of your data, from review requests and reviews to repository configuration and diff validation. There's very little you can't do!

    Our RBTools command line suite also comes with a handy Python wrapper for our API, making it even easier to work with your Review Board server in any way you need.

  • WebHooks


    Review Board can notify other services and scripts when things happen, like a new review request has been filed or a review has been posted, by adding WebHooks.

    When the events you specify occur, Review Board will send an HTTP request to any URLs you configure with a payload describing what happened. This can even be a completely custom JSON, XML, or form-data payload, making it even easier to tie into other services.

    WebHook Documentation

  • Extension Framework

    Extension Framework

    Review Board can be extended with custom features, UI, APIs, and more by writing Python extension modules. These work like browser extensions, offering all sorts of new customizations to your server.

    Companies have used this to customize the review process, take advantage of automated code review services, add custom fields for reviews, hook into other internal systems, and more.
