Elastic APM Node.js Agent
Elastic APM Node.js Agent
This is the official Node.js application performance monitoring (APM) agent for the Elastic Observability solution. It is a Node.js package that runs with your Node.js application to automatically capture errors, tracing data, and performance metrics. APM data is sent to your Elastic Observability deployment -- hosted in Elastic's cloud or in your own on-premises deployment -- where you can monitor your application, create alerts, and quick identify root causes of service issues. First, you will need an Elastic Stack deployment. This is a deployment of APM Server (which receives APM data from the APM agent running in your application), Elasticsearch (the database that stores all APM data), and Kibana (the application that provides the interface to visualize and analyze the data). If you do not already have an Elastic deployment to use, follow this APM Quick Start guide to create a free trial on Elastic's cloud. -

Ember Simple Auth
A library for implementing authentication/authorization in Ember.js
Ember Simple Auth is a lightweight library for implementing authentication/authorization with Ember.js applications. It has minimal requirements with respect to application structure, routes etc. With its pluggable strategies it can support all kinds of authentication and authorization mechanisms. it maintains a client-side session and synchronizes its state across multiple tabs/windows of the application. it authenticates the session against the application's own server, external providers like Facebook etc. The session service is the main interface to the library. It provides methods for authenticating and invalidating the session as well as for setting and reading session data. The session store persists the session state so that it survives a page reload. It also synchronizes the session state across multiple tabs or windows of the application so that e.g. a logout in one tab or window also results in a logout in all other tabs or windows of the application. -

Exokit
Native VR/AR/XR engine for JavaScript
This project enables developers to build XR experiences using the same code that runs on the web. Exokit engine is written on top of Node and emulates a web browser, providing native hooks for WebGL, WebXR, WebAudio, and other APIs used in immersive experiences. The future is immersive. The web is the best application platform. Javascript is the best ecosystem. It's not possible to do both 2D and 3D well. We don't do 2D. We can use an external 2D browser. Exokit empowers and connect apps, even (especially) if they aren't designed to cooperate. Apps should run in "reality tabs", layers of reality that blend together. Exokit is a Javascript Node.js module. C++ bindings hook into WebGL, WebXR, Magic Leap, Leap Motion, and various other device APIs. Exokit runs on Windows, macOS, Linux (x64), Linux (ARM64), and Magic Leap (ARM64). -

Fabric
Fabric is an open-source framework for augmenting humans using AI
Fabric is a command-line framework that turns a curated library of prompt “patterns” into reusable, automatable workflows for large language models. Instead of repeatedly crafting ad-hoc prompts, you pick a pattern (for research, summarization, brainstorming, code review, and more) and feed it inputs or files. The tool standardizes execution with configuration files and environment variables, enabling reproducible runs across different models and providers. Patterns can be customized with variables, chained into pipelines, and applied to entire directories, which helps scale editorial or analytical tasks. A growing catalog of community patterns serves as a knowledge base for effective prompt engineering in practical contexts. In short, Fabric makes LLM work predictable and scriptable, so teams can share methods rather than one-off prompts. -

Falcon
Free, open-source SQL client for Windows and Mac
Falcon is a free, open-source SQL editor with inline data visualization. With Falcon you can connect to your database in the Connection tab, run SQL queries in the Query tab, then export your results as a CSV or open them in the Chart Studio to unlock the full power of Plotly graphs. Optionally, you can use Falcon as a middleman between plot.ly and your database - so that when your database updates, your charts and dashboards update as well. Currently, Falcon supports connections to RedShift, MySQL, PostgreSQL, IBM DB2, Impala, MS SQL, and SQLite. In version 2.0+, the app will now automatically generate an SSL. This may take several minutes! Falcon is open source and works without an internet connection or a Plotly Chart Studio account. The software works well and we hope you find it useful. -

FileSaver.js
An HTML5 saveAs() FileSaver implementation
Have you ever wanted to add a Save as… button to a webapp? Whether you’re making an advanced WebGL-powered CAD webapp and want to save 3D object files or you just want to save plain text files in a simple Markdown text editor, saving files in the browser has always been a tricky business. Usually when you want to save a file generated with JavaScript, you have to send the data to your server and then return the data right back with a Content-disposition: attachment header. This is less than ideal for webapps that need to work offline. The W3C File API includes a FileSaver interface, which makes saving generated data as easy as saveAs(data, filename), though unfortunately it will eventually be removed from the spec. With FileSaver.js, which implements FileSaver in all modern browsers, it’s possible to generate any type of file you want right in the browser, document editors can have an instant save button that doesn’t rely on an online connection. -

Firecrawl MCP Server
Adds powerful web scraping and search to Cursor and Claude
firecrawl-mcp-server is the official MCP integration for Firecrawl that brings high-recall web scraping, crawling, and search into IDEs and agent runtimes. It exposes tools for single-page scrape, multi-URL batch jobs, site discovery, and search enrichment, returning cleaned, structured content suitable for downstream LLM reasoning. The server is designed to run with Firecrawl’s hosted API or self-hosted deployments, making it flexible for enterprise data-governance requirements. Built-in behaviors include JavaScript rendering, automatic retries, and streamable HTTP so long pages and large crawls can flow incrementally into agents. Because it’s an MCP server, clients get typed inputs/outputs and standardized error handling rather than ad-hoc prompt instructions. The repository is active, widely starred, and includes quick starts that make it easy to add web research to an agent stack. -
