    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Saka Key

    Saka Key

    A keyboard interface to the web

    Saka Key lets you control your browser with keyboard shortcuts. It is easy to use, highly configurable and will transform how you surf the web. Put away your mouse. When the web isn't accessible, it's because people who author content don't understand the benefit of making it accessible. Saka Key leverages accessibility information to make the browsing experience better for everyone. I hope this will encourage the creation of accessible content. Keyboard shortcuts are only the beginning of this journey. Screen reading and voice commands are on the roadmap. Map keyboard keys to browser tasks like scrolling, clicking links, switching, moving, closing, muting, and refreshing tabs, zooming, and navigating pages. Keyboard shortcuts are flexible, powerful, and easy to customize. Saka Key lets you easily switch between shortcut profiles (e.g. left hand, right hand, default, Vimium), and lets you import and export your settings.

    Serverless Webpack

    Serverless plugin to bundle your lambdas with Webpack

    A Serverless Framework plugin to build your lambda functions with Webpack.

Support of serverless package, serverless deploy and serverless deploy function. Support of serverless invoke local and serverless invoke local --watch. Support of serverless run and serverless run --watch. Integrates with serverless-offline to simulate local API Gateway endpoints. Cleaned up configuration.

    Shimport

    Shimport

    Use JavaScript modules in all browsers, including dynamic imports

    Shimport is a tiny JavaScript shim for using module import and export syntax in browsers that do not fully support native modules. It allows developers to work with JavaScript modules, including dynamic import behavior, across a wider range of browser environments. The project is intentionally small, making it useful when developers need compatibility without adding a large bundling or transpilation layer. Shimport helps bridge modern module syntax with older runtime support expectations. It can be useful for demos, lightweight applications, educational examples, and compatibility experiments. Its main value is making native-style JavaScript modules more broadly usable with minimal overhead.

    SingleFileZ

    SingleFileZ

    Web Extension for Firefox/MS Edge and CLI tool

    SingleFileZ is a fork of SingleFile that allows you to save a webpage as a self-extracting HTML file. This HTML file is also a valid ZIP file that contains the resources (images, fonts, stylesheets, and frames) of the saved page. This ZIP file can be unzipped on the filesystem in order, for example, to view the page in a browser that would not support pages saved with SingleFileZ. To open saved pages from the filesystem in a Chromium-based browser, SingleFileZ must be installed and the option "Allow access to file URLs" must be enabled in the details page of the extension. Otherwise, the browser must be started with the switch. To open saved pages from the filesystem in Safari, the option "Disable Local File Restrictions" must be selected in the "Develop" menu. SingleFileZ is available on Firefox, Chrome and Microsoft Edge. You can save web pages to HTML from the command line interface.

    SlimerJS

    SlimerJS

    A scriptable browser like PhantomJS, based on Firefox

    SlimerJS is a scriptable browser. It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc. It is a tool like PhantomJs, except that it runs Gecko instead of Webkit, and it is headless when using Firefox 56+. It can be used with Firefox 59. Higher version of Firefox is not supported and probably will not be supported in the future, as the development is suspended for now. SlimerJS provides the same API of PhantomJS. The current version of SlimerJS is highly compatible with PhantomJS 2.1. See current release notes in docs/release-notes-*.rst, and read the compatibility table to know the implementation level. The main goal of SlimerJS is to allow to execute all scripts developed for PhantomJS. So you could use tools like CasperJS. In fact, CasperJs 1.1 and higher can be executed with SlimerJS!
