Website development is a wonderfully rewarding profession, but at times it can be a massive pain in the neck. With our compiled list of smart online tools, we can help you reduce the pain levels considerably.

We’ve all had to hunt down that spurious bracket in a piece of code that took hours to find.  Trying to remember a particular piece of CSS syntax, which you only remember after searching online for 20 minutes. Faffing around with emails, files, servers, images – it all takes time.

Over the years I have come across resources that are so simple, yet so effective, they just make our lives as web developers easier.  They are in no particular order, and they might not all be relevant to you, but they have all individually saved me hours of time over the years and I thought it was about time that I compiled a definitive list to share.

Some are free, some are paid for – all are worth taking the time to check out and bank for a rainy day.  You never know when one of these beauties will come to your rescue saving you hours of dead time.  So let’s check out the list our web development team has put together.

Web Development Tools That Rock

htaccess check

We’ve all been there.  One small typo in a .htaccess file which brings your website down? Htaccess check is a simple online checker which will validate that your .htaccess lines are free of any syntax errors.

Simply paste your .htaccess code into the big textbox and get a report about any syntax errors in your file, including line number and reason (up to 5,000 lines permitted)

This is especially helpful for finding spaces or dots that shouldn’t be in the .htaccess file which will otherwise produce a 500 internal server error and you have no idea where to start looking to find the problem.

htaccess Tester

Cut an paste your htaccess file into the large text box and enter the URL you want to monitor.  It’ll then show you which rule in the htaccess file has been matched.

If you’ve got multiple or contradictory redirects then this tool shows you which one is kicking in which is a life saver if you are overseeing a large website migration or a complex SEO project.

Note: This tool actually stopped working, however we found an alternative here.

http status code checker

This little tool allows you to see if a 301 redirect is kicking in, which is difficult to do in your browser as caching confuses the issue.  It will also give you insight, as well as a visual representation, of redirect chains, 301 to 301 to 302 to 200.

These chains can give you speed issues, as well as affect your SEO rankings so it’s always a good idea to shut them down at source when you get the chance.

With up to 10 redirects handled, you simply need to hover over the status codes to see the details of a redirect location. Other status codes show full HTTP response headers.

Down for everyone or just me?

Are you are getting an error when viewing a URL on your machine? If so, this simple tool will check if it is a problem for everyone, or just for you.

Enter your URL in the form above to receive information about your site speed, specifically the Time To First Byte.  You get a report back which includes everything from the Namelookup time to the Connection or Redirect time.  You also receive information on the size of the Header and the Request.

Helpful for diagnosing if a slowly loading site is because of large images, HTML, CSS, code, database, etc or just a slow connection to the server.
