    CanJS

    CanJS

    Build CRUD apps in fewer lines of code

    Components shouldn’t be concerned with how data is fetched, updated, or cached. CanJS provides the right abstractions for your model code to be cleanly separated from your UI code. CanJS’s stache templating language can directly read the state and values from Promises. No need to write any extra code to determine whether a Promise is pending, resolved, or rejected. After data is created, updated, or destroyed, CanJS automatically updates your lists for you. Filtering and sorting are preserved, so you don’t have to manually update your lists or fetch the same data again. The model layer is responsible for making GET, POST, PUT, and DELETE requests to your backend. With your component UI code using the model’s standard interface to make requests, if the backend API changes, you only have to configure the model and not change every component that uses that backend API.

    Get Caption, start watching

    Caption takes the effort out of finding and setting up the right subtitles. A simple design, drag & drop search, and automatic downloading & renaming let you just start watching. Caption is multi-platform, open-source, and built entirely on web technology. Caption is completely open-source. We've tried to make it as easy as possible to contribute. If you'd like to help out by adding features, working on bug fixes, or assisting in other parts of development. Caption currently uses 2 sources to gather subtitles. We're continuously adding sources, but the app's open-source nature also allows you to add your own when desired. This can be done in Caption Core. Build the actual app for all platforms (Mac, Windows and Linux).

    Catberry

    Catberry

    Catberry is an isomorphic framework

    Catberry is an isomorphic framework for building universal front-end apps using components, Flux architecture and progressive rendering. Catberry builds a bundle for running the application in a browser as a Single Page Application. Cat-Components – similar to web-components but organized as directories, can be rendered on the server and published/installed as NPM packages. The entire architecture of the framework is built using the Service Locator pattern, which helps to manage module dependencies and create plugins, and Flux, for the data layer. Search crawler receives a full page from the server. The whole state of the application is restored from URL. Server-side progressive rendering based on node.js streams and parallel rendering of components in a browser. The framework is well-tested (code coverage is about 90%) and it is already used in production.

    ClassyVision

    ClassyVision

    An end-to-end PyTorch framework for image and video classification

    Classy Vision is a PyTorch-based framework designed for large-scale training and deployment of state-of-the-art image and video classification models. Developed by Facebook Research, it serves as an end-to-end system that simplifies the process of training at scale, reducing redundancy and friction in moving from research to production. Unlike traditional computer vision libraries that focus solely on modular components, Classy Vision provides a complete and unified framework, featuring distributed training, reproducible experiments, and flexible configuration tools. It offers high performance and scalability—capable of training models like ResNet-50 on ImageNet in just minutes—while remaining accessible to both researchers and production engineers. The library integrates seamlessly with PyTorch Hub for easy access to pretrained models and supports elastic training using PyTorch Elastic, making distributed training robust to changes in cluster resources or hardware failures.

    Concise CLI

    Concise CLI

    A CSS framework that's lightweight and easy-to-use

    The Concise CLI can be used independently of any styles. In principle, it would will with any other CSS library, framework or any existing project so long as the code is plain CSS or contains only the features that can be compiled with PostCSS. Of course, one can start writing everything from scratch using Concise as well. The core library contains the very basic styles that one might use, and contains most of the code that was available on Concise v4. No unnecessary styles are added so you can spend more time building and less time overriding. Do you need CSS components? We provide a basic UI kit for Concise CSS as an add-on. We also provide utility classes for rapid prototyping and context-dependent styles. The usual features from Sass with some custom additions using PostCSS. A framework built with design in mind. Get better results from the beginning with less code.
