Best Free Source Code Management Software

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows. You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Focus on what matters instead of fighting with Git. Whether you're new to Git or a seasoned user, GitHub Desktop simplifies your development workflow. Quickly add co-authors to your commit. Great for pairing and excellent for sending a little love/credit to that special someone who helped fix that gnarly bug of yours. See the attribution on the history page, undo an accidental attribution, and see the co-authors on GitHub. See all open pull requests for your repositories and check them out as if they were a local branch, even if they're from upstream branches or forks. See which pull requests pass commit status checks, too! The new GitHub Desktop supports syntax highlighting when viewing diffs for a variety of different languages. Easily compare changed images. See the before and after, swipe or fade between the two, or look at just the changed parts. Open your favorite editor or shell from the app, or jump back to GitHub Desktop from your shell.

A state-of-the-art AI that builds better software, cheaper and faster. K.Explorer is an AI powered Code Assistant trained on many millions of private corporate lines of code, for specific domains, and on billions of public and open-source lines of code for general purposes.

To make development faster and more agile it even supports Natural Language for programmers to get guidance while telling a text story about the code they want to write.

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.

Sourcetrail is an interactive source explorer that simplifies navigation in existing source code by indexing your code and gathering data about its structure. Sourcetrail then provides a simple interface consisting of three interactive views, each playing a key role in helping you obtain the information you need. Search: Use the search field to quickly find and select indexed symbols in your source code. The autocompletion box will instantly provide an overview of all matching results throughout your codebase. Graph: The graph displays the structure of your source code. It focuses on the currently selected symbol and directly shows all incoming and outgoing dependencies to other symbols. Code: The Code view displays all source locations of the currently selected symbol in a list of code snippets. Clicking on a different source location allows you to change the selection and dig deeper.
