Twitter早期采用[[Ruby on Rails]]框架和[[Ruby]]企业版<ref>{{Cite_web |url=http://www.forbes.com/forbes/2009/0622/software-internet-innovation-digital-tools.html |title=The Pied Piper of Pay |work=[[Forbes]] |first=Lee |last=Gomes |date=2009-06-22 |accessdate=2009-06-16 |archive-date=2009-06-12 |archive-url=https://web.archive.org/web/20090612061101/http://www.forbes.com/forbes/2009/0622/software-internet-innovation-digital-tools.html |dead-url=no }}</ref>，由于考虑到执行效率等因素并没有采用原生Ruby<ref>{{Cite_web | author = ryan king | date = 2009-09-25 | title = Twitter on Ruby | url = http://blog.evanweaver.com/articles/2009/09/24/ree/ | quote = ''We recently migrated Twitter from a custom Ruby 1.8.6 build to a Ruby Enterprise Edition release candidate, courtesy of Phusion.

2007年春季到2008年，Twitter上的消息都是通过一个名叫Starling<ref>{{Cite_web |accessdate=2009-01-11 |url=http://dev.twitter.com/2008/01/announcing-starling.html |title=Announcing Starling |publisher=Twitter |date=2008-01-16 |author=Payne, Alex |archiveurl=https://web.archive.org/web/20080120141113/http://dev.twitter.com/2008/01/announcing-starling.html |archivedate=2008-01-20 |deadurl=yes }}</ref>的持久化消息队列服务器进行处理的。但从2009年开始，Twitter已经开始逐渐在用[[Scala]]编写的程序来进行消息处理。<ref>{{Cite_web|url=http://www.artima.com/scalazine/articles/twitter_on_scala.html|title=Twitter on Scala|date=2009-04-03|first=Bill|last=Venners|publisher=Artima Developer|accessdate=2009-06-17|archive-date=2009-06-19|archive-url=https://web.archive.org/web/20090619164149/http://www.artima.com/scalazine/articles/twitter_on_scala.html|dead-url=no}}</ref>同时，这项服务提供的[[API]]允许众多网站与Twitter整合。<ref>{{Cite_web|accessdate=2008-05-08|url=http://groups.google.com/group/twitter-development-talk/web/api-documentation|title=API Documentation|publisher=[[Google Groups]]|archive-url=https://web.archive.org/web/20080506050312/http://groups.google.com/group/twitter-development-talk/web/api-documentation|archive-date=2008-05-06|dead-url=yes}}</ref>
