Serverless Framework
The easy and open way to build serverless applications
Serverless Framework gives you everything you need to build serverless applications on any cloud. It provides structure, workflow automation and best practices out-of-the-box so you can deploy sophisticated serverless architectures. It uses new, event-driven compute services, such as AWS Lambda, Azure Functions, Google CloudFunctions and more. Serverless Framework lets you build apps made up of microservices that run in response to events. These auto-scale and will only charge you when they run, which means lesser costs for application maintenance. You can also create new or extend existing commands with its great selection of community-written plugins. -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

Shariff
Shariff enables website users to share their favorite content
Shariff enables website users to share their favorite content without compromising their privacy. Some social service providers like e.g. Facebook supply official sharing code snippets that quietly siphon personal data from all page visitors. Shariff enables visitors to see how popular your page is on Facebook and share your content with others without needless data leaks. Shariff (/ˈʃɛɹɪf/) is an open-source, low-maintenance, high-privacy solution maintained by German computer magazine c't and heise online. Shariff consists of two parts: a simple JavaScript client library and an optional server-side component. The latter fetches the number of likes or shares. Share buttons and share counts work without a connection between your visitors' browsers and social networks (unless they decide to share, of course). -

Simple 8-bit Assembler Simulator
Simple 8-bit Assembler Simulator with Angular.js
A simulator that provides a simplified assembler syntax (based on NASM) and is simulating an x86-like CPU. Press Help inside the simulator to see an overview of the supported instructions. Make sure you have Grunt installed to compile the asmsimulator.js script. Run grunt to build the project. The simulator is written in JavaScript with Angular and runs on every device with a web browser. It has a lot of simplifications and constraints, but it is the basic structure of every emulator. The console output uses memory mapping and maps a specific portion of the memory to the console. Thus writing to the console output is as simple as writing into a specific memory location. The CPU reads instructions from the memory and executes them. The memory contains our program code and can be used by the program to store data. -

Size Limit
Calculate the real cost to run your JS app or lib
Size Limit is a JavaScript performance budget tool that measures the real cost of your JavaScript bundle and prevents regressions by enforcing limits in CI. It calculates not just raw bundle size, but also download and execution time under configurable network conditions, giving a more realistic sense of what users experience. The tool is modular: it offers a CLI and multiple plugins (file, webpack, time) plus presets tailored to different use cases, from big single-page apps to small npm libraries. When integrated with GitHub Actions, CircleCI, or other CI systems, it runs on every commit or pull request, failing the pipeline if a change exceeds the configured budget. It can also annotate pull requests with comments that highlight how the bundle changed, making performance regressions visible to reviewers early. With the --why flag, size-limit can analyze what contributes most to bundle size and show a dependency breakdown (using Statoscope). -

Soundnode App
Soundnode App is the Soundcloud for desktop
Soundnode App is an Open-Source project to support Soundcloud for desktop Mac, Windows, and Linux. It's built with Electron, Node.js, Angular.js, and uses the Soundcloud API. Be aware that Soundnode relies on Soundcloud API which only allows third-party apps to play 15 thousand tracks daily. When the rate limit is reached all users are blocked from playing/streaming tracks. The stream will be re-enabled one day after (at the same time) streams were blocked. Since SoundCloud applies a rate limit to third-party apps, you need to configure your own API key to make soundnode work. Unfortunately, SoundCloud suspended new application creation, so to retrieve your API key, you have to dig into the SoundCloud website. Listen to songs from your stream, likes, tracks, following or playlists. -

StoryGen Atelier
AI-assisted storyboard and video generation tool
StoryGen Atelier is an advanced creative tool that blends AI with visual storytelling, making it possible to generate fully structured storyboards and stitched videos from text prompts without requiring manual art or animation skills. Users begin with natural language descriptions of their story or scene, and the system uses state-of-the-art large models to generate both the script and corresponding frames. Once individual frames are created, a second AI model generates transition clips that smoothly link the frames into a coherent short video sequence, and the tool then assembles everything into a finished video using standard video processing tools. This pipeline transforms abstract creative ideas into shareable visual narratives, offering a powerful workflow for writers, filmmakers, content creators, and educators alike. -
