As web technologies constantly advance, the skills a developer is expected to have are constantly increasing. Web users are beginning to expect Ajax interfaces, charts and graphs and a whole host of other tricks and features. This means web developers not only have to be skilled with HTML and a server-side programming language such as PHP or Perl, but they now also need to be JavaScript gurus, Flash experts, and skilled graphic designers.
When developing your applications, you simply can’t create every element yourself. A graph or mapping solution is an application in itself, so no single developer or small team can create such components while continuing development of the primary application. This means programmers have to use third-party solutions — and thankfully there are thousands of such solutions to make our lives as developers that little bit easier.
In an effort to save you a few hours crawling the web in search of the perfect third-party solution, we have compiled this list of essential development resources.
1. Functions and Classes
You can find a whole array of pre-made classes and functions to help save development time. A great resource directory for finding the perfect PHP classes is PHPClasses.org. For those of you who use Perl, you should be familiar with CPAN.
CAPTCHA
CAPTCHA (Completely Automated Public Turing to tell Computers and Humans Apart) is the term used to describe the use of images which humans can identify, in order to ensure an automated bot/computer program isn’t accessing your application. The ideal use for this is in contact forms to ensure only humans can send messages — therefore eliminating automated spam and junk messages.
The following CAPTCHA systems can be easily integrated with your applications:
- reCAPTCHA
One of the most popular CAPTCHA systems that helps to digitize books, newspapers and old time radio shows by using CAPTCHA inputs to help translate. There is also a Perl module available for reCAPTCHA. - Securimage
Securimage is a free open-source PHP CAPTCHA script for generating complex images and CAPTCHA codes. - freeCap
A GPL CAPTCHA script to stop spam. - HN CAPTCHA
A CAPTCHA script written in PHP, licensed under LGPL.
Date Manipulation
Manipulating dates in your applications can be a time-consuming process. PHP and Perl include numerous functions for automating the process, but often don’t offer all the required functions.
The following date manipulation functions can be easily integrated with your applications:
- PEAR Date
Generic PHP classes for representation and manipulation of dates, times, and time zones without the need for timestamps. - Date Class
This PHP class allows you to add or subtract periods from dates, and calculate the difference between two dates. - Date manipulation in PHP
A PHP tutorial on PHPBuilder.com, guiding you through a number of common date manipulation processes. - Date::Calc Perl Module
A powerful Perl module for date calculations based on the Gregorian calendar.
Image Manipulation
Manipulating images is a common requirement. Whether you want to resize your images while maintaining aspect ratios, or add watermarks, the process can be entirely automated using a server-side language like PHP or Perl.
- Image Manipulation Class
Resize, flip and rotate images in PHP. - PHP Thumbnailer
A lightweight image thumbnail tool. - PHP GD
GD is a powerful image manipulation library. - Perl GD
GD image manipulation module for Perl.
Form Validation
Form validation is critical to ensure users enter form information in a suitable format, and is especially important to protect your application against attacks.
- validaForms
A PHP form validation class. - User Input Validation Class
A basic PHP validation class for user input. - Validate Form Fields Script
A basic PHP script for form validation. - WWW::FieldValidator
A simple Perl form validation module.

Password validation is important to ensure your users choose passwords that offer an adequate level of security to prevent their accounts from being compromised.
- Strength Test
A useful PHP function for password strength testing. - Password Checker
A PHP class for generating and testing the strength of passwords. - Data::Password::Check
A useful Perl module for password checking.
2. Ajax and JavaScript
Ajax is a web methodology that uses JavaScript to make HTTP connections to retrieve and process data for the purpose of dynamically updating the content of a static web page. Ajax enables you to update content within a web page without reloading the entire page, thus reducing load times and server loads, making your web pages more interactive and intuitive. A great resource for Ajax tools is MiniAjax.
Auto Suggest
Auto suggest or autocomplete tools are usually applied to text inputs like search fields. When a user begins their input, the input field shows a list of options that match what they have entered so far. This enables users to enter their input more quickly, and can also help them enter terms that match search data that are more likely to return relevant results.
- Facebook-Style Autosuggest
A great Facebook-style auto suggest tool which supports multiple selections. - Autosuggest / Autocomplete with Ajax
A great auto suggestion tool which can use XML or JSON data sources. - Ajax.Autocompleter
A very flexible autocomplete powered by script.aculo.us. - Adobe Labs Spry Auto Suggest
A useful autosuggest tool provided by Adobe Labs. - Google Suggest Style Filter
An autocomplete data filtering tool.
Calendars
Ajax calendars are extremely useful when you need your users to enter a date. They reduce confusion over date formats, and enable users to easily find the date they are looking for rather than typing a date format string.
- Vista-Like Ajax Calendar
A great Ajax calendar that uses Mootools. - JS Calendar in DHTML Suite
A powerful calendar tool that supports features like multiple connected calendars. - AJAX Calendar with PHP and MySQL
An open source Ajax calendar tool. - Super AJAX Calendar
A PHP and mySQL Ajax calendar. - dhtmlxScheduler

Sliders
Ajax sliders enable users to use an interactive draggable element to select values. These are very useful for features like colour pickers as they enable users to ‘slide’ through a range of colours to select the one they want.
- Accessible Slider
A well-coded and nicely-designed slider tool that features range sliders. - Phatfusion Slider
An Ajax slider tool with a “snap to steps” feature. - AJAXEngine Sliders
Sliders that are part of the AJAXEngine project. - Slider Using PHP, Ajax And Javascript
A basic, but useful, Ajax slider tool. - WebFX Slider

Data Grids
Ajax data grids enable you to display data in a table, but with the benefit of features like column sorting and pages without the need to reload the entire page.
- Grid3
A useful data grid tool which is part of the Ext JS library. - dhtmlxGrid
A powerful data grid tool that includes column sorting and search functionality. - Unobtrusive Table Sort Script
A data grid tool that includes multiple column sorting. - AJAX Data Listings Engine

Draggable Content
Ajax-based draggable content features can be very useful when used appropriately. Such tools enable users to reorganize a page to suit their needs, and can also serve as a basis for an interactive feature like a shopping basket.
- Draggable Content Scripts
dhtmlgoodies.com provides numerous draggable content scripts, including an image cropping tool and a sortable list script. - DragResize
A great tool for draggable content with resize functionality. - Drag & Drop Sortable Lists
A simple tool for creating sortable lists. - Scriptaculous Draggable
A powerful draggable content tool which is part of the script.aculo.us framework.
Image Enlarging
Image enlarging scripts, similar to JavaScript light boxes, enable the user to enlarge or zoom in on an image chosen from a set of thumbnail images.
- Highslide JS
A great tool for managing image enlarging and modal windows. - FancyZoom
A useful JavaScript image zoom tool. - TJPzoom 3
A great image magnifying tool. - Ajax Script To Scale Images
A basic script for showing enlarged versions of thumbnails.
Galleries and Slideshows
Image galleries are very useful when you have a collection of images to show, they allow users to easily browse your images, and features like slideshows allow users to sit back and enjoy watching your images.
- minishowcase
A simple Ajax/JSON image gallery. - Animated JavaScript Slideshow
A very lightweight JavaScript slideshow with animated captions. - Hoverbox Image Gallery
A simple gallery with mouse-over image viewing. - TripTracker
A lightweight image viewer with slideshow. - Agile Gallery (Ajax Version)

- Starbox
A flexible star rating system using Prototype. - Unobtrusive AJAX Star Rating Bar
A useful PHP star rating tool. - CSS: Star Rater Ajax Version
A simple Ajax star rating tool.
Colour Pickers
If you want to let users choose colours in your application, it’s better to present them with an interface rather than asking them to enter a HEX code. Colour pickers allow users to choose colours from a colour palette which then generates a HEX code for use in your HTML.
- jscolor
A simple pop-up colour picker. - JavaScript Color Picker
A colour picker that handles RGB, HSL, and Hexadecimal values. - Tigra Color Picker
A very basic colour picker. - Photoshop-like JavaScript Color Picker

Progress bars are very useful when handling user uploads or pages which can be slow to load; they keep the user informed that progress is being made and that the page is loading.
- jsProgressBarHandler
A flexible and well designed progress bar tool. - YUI Loading Panel Widget
An attractive loading bar tool. - Simple Javascript Progress Bar with CSS
A simple, but useful, progress bar tool. - Uploadify
A jQuery-based file upload tool with progress bar.
3. APIs
An API (Application Programming Interface) is a set of program functions which can be accessed by another application. One example is a currency conversion API that retrieves currency conversion data by allowing the user to enter a base currency, an amount, and the desired result currency, which returns a result via the API.
- Alexa Top Sites
This API provides access to lists of web sites ordered by Alexa Traffic Rank. - bit.ly API
A useful API for the bit.ly URL shortening service. - Blinksale API
Enables you to access Blinksale data such as invoices and customer data. - FoXRate
A basic currency conversion API. - eBay API
eBay’s API which allows you to submit items to be listed and obtain listing data. - Twitter API
The Twitter API allows you to have access to Twitter data, including user and status information.
4. IP Locations
Finding out where your visitors are located can be valuable from a development standpoint. It can help you understand your visitors so you can design your site to better suit their needs. IP location information can help you determine where a user is located, enabling you to display content in the their language. You can also optionally customize other information such as currencies and shipping costs.
- OpenCrypt IP Location API
A hosted API service for determining user location by country. - IP Details
A PHP class for determining geographical locations based on IP address. - GEO-IP
A free IP to country database.
5. Charts and Graphs
Charts and graphs enable you to display complex data visually. This is useful for example when trying to determine information like daily pageview counts from detailed statistical logs, enabling the user to immediately see how the data varies over a period of time.
- amCharts
A powerful Flash charts tool which supports 3D charts and the ability to combine different graphs. - FusionCharts
A well designed and stylish 3D charts tool. - XML/SWF Charts
A highly customizable Flash charts tool. - JFreeChart
A free Java-based charting tool. - pChart

6. Maps
Once you are using IP location tools like those listed above, you will have a collection of user location data. What better way to display it than with an interactive map. Interactive maps are also useful for understanding user location data such as sales information, for example, when you receive delivery and billing address info from a user.
- amMap
An interactive mapping tool which includes drill-down functionality. - Google Charts API
A great mapping tool, though limited to a small map size. - Flashmaps
A great collection of different Flash mapping tools.
7. Audio Players
When used well, playing audio on your web site can be a great way of setting a mood or getting a message across.
- XSPF Web Music Player
A Flash-based open source audio player which includes playlist support. - Flash MP3 Player
A free PHP and Flash MP3 player. - TSPlayer
A Flash-based skinnable MP3 audio player. - E-Phonic MP3 Player
A lightweight skinnable MP3 audio player with real-time visualization effects.
8. Video Players
Video content is now becoming a standard, but getting the right video player is very important. Video content is the ideal, and often expected tool for promotion, so getting a player which suits your site and needs is now a critical design and development choice.
- OS FLV
An open source and well featured Flash video player. - Flowplayer
A full-featured and highly customizable Flash video player. - JW FLV Media Player
A very powerful and flexible Flash video player. - FLV Player
A stylish and customizable Flash video player.
9. Video Conversion
Video conversion/encoding can be a tricky business. Videos can be in a wide range of formats but most players only support a handful of those. If you don’t have a server which supports ffmpeg, converting videos to a format suitable for your player is usually an offline and manual task.
- OpenCrypt Video Conversion API
A powerful video conversion API for generating FLV video files. - Hey!Watch
An online video encoding platform. - Online FLV Converter
An online FLV video converter. - FlashVideo Module API
A Flash video encoding API targeted to the Drupal community.
10. WYSIWYG Editors

Can you email me some ajax info please
These are hardly what I would define as essential web development tools.
Surely the only essential development tools are
1) A text editor
2) A webserver
and maybe 3) image editing software.
Anything else is just a nice extra
i thought exactly the same while reading this!
But i nice list! ^^
Maybe they’re not “essential” but you sure wouldn’t want to take the time building all of these things yourself. Great roundup, thanks!
Lots of neat tools though. Not all essential, obviously, but neat nonetheless. Notice how many of them are ajax. There’s a web 2.0 technology that not’s going anywhere soon.
nice tools but not all essential
Thanks
wow…. what a great list!
great compilation and useful list. thanks for share Neil Skirrow :)
AWESOME collection. First time visit and impressed.
Awesome list! I used a lot of tools in the past .. and now much more in the future!
Great list of resources for web developers. Each in that list should be implemented into a highly dynamic and interactive website.
Good list, actually a few items will be defo useful to me. Surprised not to see more jquery examples though.
I’d love to see best practices for setting up testing servers as well. Trying to figure out how to do it the smoothest way from a production standpoint.
Nice list…some great tools that I didn’t know about!
Good job dude, thanks
Great list! Thanks!
Awesome list.. Very useful collection.
you did amazing job in this helping article where you sharing most useful web development tools.
nice list thx, thats good
Thanks for that great collection!
Thanks for that excellent list !
how can there be 100 essential web dev tools? I think we need to reevaluate our use of the word “Essential”…
I doubt that “WE” are the ones in need of a dictionary.
Some of these don’t even fit in a category of “things you should consider”, like the Captchas for example. There are waaaaaaay too many reasons Captchas suck donkey schnitzel that we should try to avoid them as much as possible, not recommend them.
Great collection. Thanks…
Great post, I enjoyed this! Any thoughts anyone on tools for the C# (ASP.NET) developer? I see a lot of designers using PHP and I use a Mac @ home but an trying to force myself to use Microsoft ASP.NET since that is what I use @ the office.
“This means web developers not only have to be skilled with HTML and a server-side programming language such as PHP or Perl, but they now also need to be JavaScript gurus, Flash experts, and skilled graphic designers.”
WRONG! Design should be left to designers. Just like back in the 90′s all too often developers think they can be designers, too. It all ends up badly.
Some developers have a decent sense of what looks nice compared to what does not. But most just think code and numbers. Just as developers cringe when they see designers building a site in Dreamweaver’s WYSIWYG editor, designer’s too cringe at seeing developers trying to strut their stuff on the look and feel of a site.
This the proof of google trend result, it explain that designing is more than developing. Most developer now customizing to develop a project.
It’s great!! Thanks!!
this is the best web development article I’ve read for long time, and this is the first time i comment on this website because this is must-read article for every web designer or developer.
good work Neil Skirro; and thank you.
Awesome collection as always. Thanks for this great collection.
Amazing Article,that was useful
Thanks, really nice collection =)
Check these sites for your soloutions to questions.

Great Article!
If I could write like this I would be well chuffed ;-)
The more I read articles of such quality as this (which is rare), the more I think there might be a future for the Web. Keep it up, as it were.
I love these essentials
Very cool. Good Stuff!
Awesome Man!
Very useful, thanks for sharing :)
Perfect. Incredible list, thanks a lot.

Wow! Excellent List. Most of the tools are very helpful and useful for our daily use. Thanks a lot for sharing!
Useful List!Thanks.
Wow, a really cool and great state-of-the-art summary! Two big thumbs up for the effort.
Great list! Next time please consider mentioning our opens source form builder library: ValidForm Builder.
Check out http://www.validformbuilder.org/ . We’ll be online with a complete documentation next week.
Easy to use save XHTML valid web forms.
As someone mentioned earlier, I was surprised not to see more JQuery examples mentioned… which in some cases are easier and less complex than the examples you provided.
great list….thnx
superb collection…keep up the good work
Great Colection!!!
thnks really important tools ,
So usefull! THANKS A LOT!
Really great info. Thanks for the post
Pretty amazing compilation. Take notes that YUI also offer a RTE that is pretty easy to use and complete.
Definitely a good list. There is a real divide developing between designing and developing.
Nice list! and good organization.
If you are a designer and need to learn more about common user interface controls, we
published a list of 43 Essential Controls in March this year, an update of the popular 30 Essential Controls article in 2009. Just Google the term ‘essential controls’.
Both lists talk about the (+20) most popular RIA frameworks and libraries, like JQuery, ExtJs, Flex, Laszlo, Silverlight… and which ones provide which UI controls.
Nick,
I love your stuff; it is really useful. Keep up the good work.
