When working on any type of documents (whether it is code or not), we may want to compare different versions to see what has changed.

Some editors have this feature built-in where some don’t. Mergely is a free-to-use web app for making such a difference analysis quickly.


Documents can be uploaded with ease (or by mentioning URLs), the differences will be highlighted and it is also possible to merge them.

Mergely is also an open source JavaScript library (non-commercial) where you can integrate into your own projects.

Knowing the number of characters, words or paragraphs within a given element is sometimes necessary (when limiting them, informing the users, etc.).

Countable is a tiny and standalone JavaScript function that brings the ability to count all three.

It works very straightforward and has the option to count the inputs with stripping HTML tags.


Kartograph is a framework for creating interactive maps without any mapping provider (like Google Maps).

It consists of 2 libraries:

  • a Python library thatrenders vector maps from shapefiles or PostGIS and converts them to SVG
  • a JavaScript library for turning these SVG data into interactive maps

If you already have the SVG data (for ex: any drawing can be converted to SVG with Adobe Illustrator), only the JavaScript library can help too.

The JS library uses jQuery + Raphaël, outputs can be styled with CSS and a very good documentation is provided.

  • jsDraw2DX is a standalone JavaScript library for creating any type of interactive graphics with SVG (and VML for old IE browsers).

    Besides the ability to generate all basic shapes like line, rectangle, polygon, circle, ellipse, arc, etc., the library can draw curves, beziers (any degree), function plots, images and decorated text.


    The library is object-oriented and its coordinate system + scaling can all be configured.

    As it uses SVG, interactivity can be easily accomplished by manipulating the DOM.

    P.S. jsDraw2DX is built by the creators of jsDraw2D which draws any shapes using JavaScript.
