This site archives demos created for Doom and related games (Heretic, Hexen, etc). Demos may be recorded using any source port, although care should be taken to use the intended environment for each WAD. Post your demos to the Speed Demo Forum on DoomWorld. The site is currently a work in progress: most of the backend is complete, but much of the work needed to parse old data and extract new data is still underway.
The following categories and types are the most common and widely recognized, but this archive will host any demo.
|UV Speed||-||Exit as fast as possible on skill 4.|
|UV Max||-||Exit with all monsters dead (except lost souls) and all secrets collected on skill 4.|

For demo recording and playback information, check the detailed welcome thread at the Speed Demo Forum. The majority of players prefer to use PRBoom+ to record and play demos for vanilla, limit-removing, mbf, and boom formats. (G)ZDoom is generally only used for (G)ZDoom-specific wads. Note that PRBoom+ maintains backwards compatibility, but (G)ZDoom does not. Always use the source port version that a (G)ZDoom demo was recorded on to ensure proper playback.
