JS Bin
JS Bin
JS Bin is a tool for experimenting with web languages. In particular HTML, CSS and JavaScript, but JS Bin also supports other languages too (like Markdown, Jade and Sass). JS Bin is ultimately a code sharing site. Along with the code, the complete output of the code is also shared with other developers, colleagues and/or students. As you type into one of the editor “panels”, you and anyone watching your bin will see the output being generated in real-time in the output panel. There’s many features tucked away inside JS Bin, but our design principle is that everyone gets a cursor. So when you arrive for the first time, you’ll be greeted with an initial start HTML page and very little else (though you can customise your default code). If you register (which is free and simple), your profile will remember which bins you created, but also give you a shortcut URL that always takes you to the last bin you worked on.Starting Price: $17.82 per month -

Teletype for Atom
Atom
Teletype for Atom lets developers share their workspace with team members and collaborate on code in real time. Working on code together in real time is valuable for knowledge sharing and producing quality software. The Teletype package for Atom aspires to make it as easy for developers to code together as it is for them to code alone. Teletype introduces the concept of real-time "portals" for sharing workspaces. When a host opens a portal, their active tab becomes a shared workspace. There, invited collaborators can join in and make edits in real time. As the host moves between files, collaborators follow along with the active tab automatically. There's no centralized server to spy on your keystrokes, and Teletype uses WebRTC to encrypt all communication between collaborators. What happens in the portal stays in the portal.Starting Price: Free -

Prerender
Prerender
Get higher rankings by serving crawlers a static HTML version of your Javascript website, without compromising your customers’ experience. Prerender® is a SaaS platform that makes your JavaScript website SEO-friendly. Before your customer can find your website on search engines like Google, it first has to be crawled and indexed by one of their web crawlers, such as Googlebot. They do this by reading and cataloging a stripped-down, HTML version of your website with the visual and interactive elements taken away. This normally isn’t an issue if your website is built in static HTML, and typically takes just a few days. If your website is made in a JavaScript framework, it’s a different story. While Google can crawl websites built in JavaScript, it’s much harder for them to do. It can easily take weeks before your JavaScript website can be indexed and found in the search results. Google will see all of your content and links, and get your website in front of your customers in no-time.Starting Price: $90 per month -

Bright Security is a developer-centric Dynamic Application Security Testing (DAST) solution that helps organizations ship secure applications and APIs quickly and cost-effectively. Its approach enables quick and iterative scans to identify critical security vulnerabilities early in the SDLC without compromising on quality or delivery speed. Bright empowers AppSec teams to provide governance for securing APIs and web apps while allowing developers to take ownership of security testing and remediation work. Unlike legacy DAST solutions built for AppSec professionals, which are complex to deploy and find vulnerabilities late in the development process, Bright's DAST solution is optimized for the DevOps world. It can be deployed as early as the Unit Testing phase and run throughout the SDLC, learning and optimizing from every scan. By enabling organizations to detect and remediate vulnerabilities early in the SDLC, Bright reduces risk at a lower cost and effort.
