Bower
Bower
Web sites are made of lots of things, frameworks, libraries, assets, and utilities. Bower manages all these things for you. Keeping track of all these packages and making sure they are up to date (or set to the specific versions you need) is tricky. Bower to the rescue! Bower can manage components that contain HTML, CSS, JavaScript, fonts, or even image files. Bower doesn’t concatenate or minify code or do anything else, it just installs the right versions of the packages you need and their dependencies. To get started, Bower works by fetching and installing packages from all over, taking care of hunting, finding, downloading, and saving the stuff you’re looking for. Bower keeps track of these packages in a manifest file, bower.json. How you use packages is up to you. Bower provides hooks to facilitate using packages in your tools and workflows. Bower is optimized for the front-end. If multiple packages depend on a package, jQuery, for example, Bower will download jQuery just once.Starting Price: Free -

WTForms
WTForms
WTForms is a flexible forms validation and rendering library for Python web development. It can work with whatever web framework and template engine you choose. It supports data validation, CSRF protection, internationalization (I18N), and more. There are various community libraries that provide closer integration with popular frameworks. WTForms tries to provide as usable an API as possible. We’ve listed here some of the known libraries to work with WTForms, but if it’s not listed, it doesn’t mean it won’t work. Pretty much any ORM or object-DB should work, as long as data objects allow attribute access to their members. WTForms uses unicode strings throughout the source code and assumes that form input has already been coerced to unicode by your framework. WTForms fields render to unicode strings by default, and therefore as long as your templating engine can work with that, you should have no unicode issues.Starting Price: Free -

broot
broot
The ROOT data analysis framework is used much in High Energy Physics (HEP) and has its own output format (.root). ROOT can be easily interfaced with software written in C++. For software tools in Python there exists pyROOT. Unfortunately, pyROOT does not work well with python3.4. broot is a small library that converts data in python numpy ndarrays to ROOT files containing trees with a branch for each array. The goal of this library is to provide a generic way of writing python numpy datastructures to ROOT files. The library should be portable and supports both python2, python3, ROOT v5 and ROOT v6 (requiring no modifications on the ROOT part, just the default installation). Installation of the library should only require a user to compile to library once or install it as a python package.Starting Price: Free -

They’re used for body text, but also for headings and list items like bullets. You’re free to specify both width and height, but usually, you wouldn’t want to. If you specify only one, python-docx uses it to calculate the properly scaled value of the other. This way the aspect ratio is preserved and your picture doesn’t look stretched. If you don’t know what a Word paragraph style is you should definitely check it out. Basically, it allows you to apply a whole set of formatting options to a paragraph at once. python-docx allows you to create new documents as well as make changes to existing ones. Actually, it only lets you make changes to existing documents; it’s just that if you start with a document that doesn’t have any content, it might feel at first like you’re creating one from scratch.Starting Price: Free -

Semantic UI React
Vercel
Semantic UI React is the official React integration for Semantic UI. jQuery-free, declarative API, augmentation, shorthand props, sub-components, auto controlled state. jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components.Starting Price: Free -

Pleasant3D
Pleasant Software
I frequently had the problem that downloaded STL files needed some minor editing in order to be printable on my 3D printer. Most of the time it was just a simple move to the center of the build platform or a resize. In addition to that, I already wrote OpenGL code to visualize STL and GCode files a couple of months ago for another larger project. Finally, I had sometimes a problem that I downloaded an ASCII encoded STL file and wanted to open the file in my 3D/CAD application. Since this application can only read binary STL files I needed an easy way to convert ASCII STL to binary STL. So I wrote Pleasant3D, a small utility that solves these problems and uses the above-mentioned visualization code to display STL and GCode files. This version implements better error checking in the Quicklook plugins and falls back to displaying the standard document icon if the Quicklook generation fails. That way quicklockd doesn't crash anymore in case of problems.Starting Price: Free -

Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance.Starting Price: Free -

Bideo.js
Bideo.js
Bideo.js is a JS library that makes it super easy to add fullscreen background videos. Fullscreen HTML5 background video for the web. Want to play a video in the background of a container or body itself? This plugin will help you do exactly that. The video element in use will automatically adapt to the container's dimensions. It will also resize as the browser window resizes. The plugin doesn't support any overlay as it is easy to implement that with plain HTML/CSS in your code. Video might take a few seconds to load, especially because the sources are added via JS which is something you'll load after the DOM's loading. Until then, you may want to show a video cover, which will be the same as the first frame or the video (or some other image). The support for this is not in the plugin as it's fairly simple to achieve this via just HTML/CSS (just like overlays).Starting Price: Free -
