50 Essential Online Tools for Every Computer Science Student

Computer science students need to acquire skills in multiple areas — arguably more so than any other study disciplines. So not surprisingly, they need a large toolbox, for any of several activities encountered in the typical college program. To that end, here is a reference list of 50 essential tools (software and resources) for computer science students.


  • We’ve left out the typical Web browsers, email clients, most IM/ chat clients, search engines, video sharing sites, etc., and given a sample of tool categories that have numerous options.
  • Some tools listed are free, others follow a freemium model (free with paid upgrade options).

Communication and Collaboration

  • Google Hangouts: Free group conversations and live voice and video, from a browser or mobile app.
  • Strike: Create Web-based task lists and share with classmates, colleagues and other collaborators.

Data Parsing, Data Conversion, File Retrieval, Format Checking

  • JSONLint: Validate JSON content and convert to prettyprint mode.
  • Mr. Data Converter: Convert between JSON, XML, HTML, CSV and other data formats.
  • net2ftp: Use this Web-based FTP client to download assignments or upload your course work when using public campus computers.

IDEs, Code Snippet Savers, Coding Sandboxes

There are a lot of code sandboxes out there, most that handle multiple programming or scripting languages. Here’s a sampling of a few.

  • Chop: Save code snippets with notes and share with classmates, project partners or teaching assistants.
  • Gist: Gist, a collaborative code and data snippet repository from Github that lets you save secret or public snippets that people can fork as well as leave comments or ask questions.
  • Ideone.com: Run and debug syntax-highlighted code in the browser for over 40 programming and scripting languages.

Web Site Development and Testing

  • Browsershots: Test browser compatibility across OSes by requesting bulk screenshots for an URL running on up to 180 browsers.
  • CodePen: A Web browser-based sandbox for front-end Web development, with markup options for Haml, Markdown, etc., stylesheet options for Sass, LESS or Stylus, and scripting options for JavaScript, CoffeeScript or LiveScript.
  • Dabblet: A sandbox with configuring interface for testing HTML+CSS code snippets — with save-to-Github Gist (above).
  • IE NetRenderer: For when you absolutely need to check how Internet Explorer renders a page in versions 5.5 and 6 through 11.

  • JSFiddle: A front-end Web page development sandbox with real-time collaboration including screen sharing, text and audio chat, and more.
  • Web Design Tools: Not a tool per se, but a big list of over 80 Web design tools for browser, desktop and mobile use.

Reference, Notetaking, Bookmarking, Studying, Planning, Projects, Presentations

  • EasyBib: When you have to cite references in a proper format (MLA, APA, Chicago, AMA, etc) for a term paper, use Easybib to help you get the citation right, whether the reference is a Web site, book, newspaper, journal or any of a total of nearly 60 source types.
  • Evernote: Save notes, bookmarks, Web clippings, sketches and more, from a browser (desktop/ laptop) and sync via the Cloud for access from other computers or mobile devices.
  • ExamTime: There’s a lot to learn in Comp Sci; test your ongoing study efforts by creating and using your own notes, quizzes, flashcards, free-form mind maps with multiple sticky notes per node — or use the searchable study resources created by other users.
  • Freedcamp: A free (limited) alternative to Basecamp, for managing class projects, with collaboration features, notification via IM/SMS and email, project templates and more.
  • Gliffy: For when you need to create wireframes, flowcharts, sitemaps, network diagrams and more — with collaboration features. Also available as an extension/ plugin for select Web browsers.
  • Pearltrees: Organize your Web page bookmarks, files, photos, and notes in a structured, mind map-like, navigable visual format, via drag-and-drop or add-by-email feature, and social sharing.
  • PivotalTracker: Simple project management, with free solo accounts, plus sync to Cloud for computer and mobile device access.

  • Prezi: Instead of boring old slides for your class presentation, use Prezi to create dynamic, more mind map-like zooming presentations. “Edu Enjoy” license free for students registering with a school email address.
  • Readability: Makes ugly, unreadable Web pages easy to read, with an estimated reading time displayed.
  • SlideShare: Create and share Web slideshows, infographics and other content for your big project presentation.
