Hi, Not sure if this has been done before, but I think it will be a good idea to get a list of (free) online tools available that help application development. By 'online tools', I mean in-browser applications which require no extra downloads. I always seem to stumble upon cool applications (often after I needed it), so I thought it would be handy for everyone if there was a centralised list, making it easier to see what's available. I'll start off with a few I use:
- Test Regular Expressions online: http://www.gskinner.com/RegExr/
- Test Javascript/CSS online: http://jsbin.com
- Create mathematical equations for documents: http://www.codecogs.com/latex/eqneditor.php
- Check site in different browser sizes: http://browsersize.googlelabs.com/
- Color scheme designer for websites: http://colorschemedesigner.com/
- Mozilla Bespin - a code editor in the cloud: https://bespin.mozilla.com/
- yUML - create UML diagrams: http://yuml.me/
- PageTest - Test page performance: http://www.webpagetest.org/
- Browsershots - How your site looks in different browsers: http://browsershots.org/
- ColorPicker - Find colors easily: http://www.colorpicker.com/
Feel free to add any useful tools, as long as they can help in developing applications.
