Doom Speed Demo Archive

The Doom Speed Demo Archive (often abbreviated DSDA, formerly the DooMed Speed Demos Archive) is a website that collects speedruns for various PWADs. It was created by Opulent on September 1st, 2000. From November 12th, 2008 to November 12th, 2019, it was run by Andy Olivera.. On November 12, 2019, Andy Olivera announced that he was officially retiring from maintaining the DSDA, and encouraged readers to visit a new incarnation of the DSDA created by speedrunners Kraflab and Zero-Master.

This new version was completely rewritten in a modern layout to allow updates by a team of maintainers, support non-Doom games, show detailed demo information such as times in tics, and more. All of the demos from Olivera's DSDA have been mirrored, and more features are being continuously developed, including an API.

As of June 2020, the archive contains well over 58,000 demos by more than 740 speedrunners. It allows many different demo types, expanding on those allowed in Compet-n. It also offers tutorials on recording and playing demos, hosts binaries of various source ports and useful utilities. The DSDA lists all players and their contributions to the archive, including total running time.

The domain name for the second iteration of the DSDA expired on November 11, 2020, and it is impossible to surf the site since then.
