Didn't see this mentioned, but Wordpress and Drupal have had a huge impact on my early career.
Wouldn't count them as developer tools per se, but as a software provider, I could serve a lot more customers with ease and confidence thanks to hundreds of thousands of man hours put in by the Wordpress and Drupal developers.
