Review just about anything
Projects are more than just a collection of source code. With Review Board, you can review screenshots, documentation, schematics, presentations, contracts, diagrams, and just about anything else, all in one place.
Whether your projects are built by people, AI, or a combination of both, Review Board can help ensure the end result is a quality product.

One of the pioneers of modern code review
When we started out in 2006, code review mostly meant e-mailing diff files back and forth. We wanted a better way, and began inventing many of the code review features that have since become industry standards.
We built what you know and love today, and are pioneering what you'll use tomorrow.
Review code in any language on almost any source code management system (Git, Subversion, Mercurial, Perforce, ClearCase, and many more) with abilities including:
- Multi-line commenting
- Moved code detection
- Smart indentation-aware line changes
- Commenting on any line in a file, even outside the diff
- Tracking the evolution of any change, making it easy to see what's new since your last review. li>

- Contextual commenting on regions of images
- Side-by-side image diffs
- Color-based image diffs

Take review to another level with Document Review
No other code review tool can review documents like Review Board.
Review and diff Office documents, contracts, technical diagrams, schematics, reports, and anything you can export to PDF, with features including:
- Contextual commenting on regions of documents or selected text
- Compatibility with nearly any document type
- Table of contents and thumbnail-based navigation
- Side-by side comparisons between document revisions, with changes highlighted

Goodbye Pull Requests, hello Review Requests
Review requests collect code changes, screenshots, mockups, documentation, and other files and assets all in one place, and where you'll go to track your task's reviews, discussions, CI build statuses, modifications, and audit trails.
They're more than just a Pull Request.

Review, discuss, and track issues so nothing gets missed
Review Board's reviews don't bury important discussions and tasks somewhere in a diff viewer like most pull requests do.
Each review is a self-contained discussion between you, the reviewer, and anyone with something to contribute. All in one place, threaded, and easy to follow.
Comments are shown alongside relevant sections of code, images, or documents, giving you all the context you need to follow along, and can be expanded to see more.
Comments may open an issue, a To Do item that must be addressed before the work is approved. This way, no important task gets missed.

Every review request you care about, all in one place
Review Board's Dashboard gives you a birds-eye-view of everything that matters for your day. Every review request waiting for your review, and every one of your review requests waiting for reviews from others. Featuring:
- Filtering review requests by groups and projects
- Helpful visuals for determining review status
- Several customizable sortable columns to choose from
- Bulk-closing, archiving, and muting of review requests

Automatically review code with Review Bot and CI solutions
Review Board integrates with Continuous Integration and code checking solutions to provide automatic reviews on your code.
Jenkins, CircleCI, and Travis-CI are supported out of the box, and with our free Review Bot add-on, you can connect to a wider collection of tools. You can even craft your own in Python!

Command line users will love it!
Our RBTools command line tools can be used to post changes for review, land changes in your tree, test out other users' reviews, check the status of your review requests, and much more.
Its built-in Python API can be used to craft custom solutions, IDE integrations, and automations useful to your team.
