Launchpad vs. Python vs. Review Board vs. jscoverage Comparison Chart

It brings communities together — regardless of their choice of tools — by making it easy to share code, bug reports, translations and ideas across projects. With Launchpad, you can share bug reports, statuses, patches and comments across project boundaries. You can even share bug data with other trackers, such as Bugzilla and Trac. There's also everything else you need in a bug tracker: web, email and API interfaces, links between bugs and fixes, team-based delegation and more. When they're ready, they can upload their branch to Launchpad and propose it for merging back into your trunk. Code review — by web and email — gives you a public forum to discuss and approve or reject the merge. Launchpad makes translation easy for everyone. Translators get a simple web interface, with automatic suggestions from a library of more than 16 million strings.

Code review doesn't have to be so hard. Review Board takes the pain out of code review, saving you time, money, and sanity so you can focus on making great software. 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. 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. Sometimes you'll have other text content that's not part of your source tree.
