Quake is a 3D first-person shooter released in 1996 by id Software. Its engine was licensed out to many companies, including Valve. GoldSrc is based off of Quake engine code, specifically, GLQuake and Quakeworld (with some Quake II code), with it's successors Source and Source 2 both still retaining some residual Quake code.
The Quake Engine introduced many of the concepts still used in Source today, such as the modern variant of the BSP, the use of a PVS, precomputated lightmaps, visleafs and brush entities. Early GoldSrc multiplayer was based off the QuakeWorld multiplayer code (until 2001, when some Quake III[citation needed] code was added).
The Quake Engine and its successor, the Quake II Engine, are now both retroactively referred to as id Tech 2. Both engines have been released as free and open source under the GPLv2 license, allowing for many source ports to be created, which add quality-of-life improvements and are now the preferred way of playing the game, including a remaster released in 2021.
Compilers
Quake also uses three compiler tools in compiling a map: QBSP, VIS, and LIGHT. The code for these was used as the basis of the compiling tools used by the compilers used by the Valve engine map compilers, as seen below:
| Original Quake compilers |
Original  GoldSrc compilers |
ZHLT, VHLT, and derivatives |
 Source compilers |
 Source 2 compilers
| |
|---|---|---|---|---|---|
| CSG | part of QBSP | QCSG | HLCSG | part of VBSP | resourcecompiler |
| BSP | QBSP (Source code) | QBSP2 | HLBSP | VBSP | |
| VIS | VIS (Source code) | VIS | HLVIS | VVIS | |
| RAD | LIGHT, no radiosity lighting (Source code) | QRAD | HLRAD | VRAD | VRAD2 ( and earlier)VRAD3 (in all games since  )

ericw-tools uses the same nomenclature as the original Quake compilers.
Source ports
Since the release of the Quake source code, there are various source ports available:
- Quakespasm - Limit-breaking source port focused on vanilla accuracy. Fork of the long-deprecated FitzQuake. Actively maintained.
- Quakespasm-Spiked (QSS) - Fork of Quakespasm that can run at higher frame rates than 72FPS without breaking physics.
- vkQuake - Fork of QSS running on Vulkan, with additional features. No longer maintained as of 9 May 2023.
- Quakespasm-Spiked (QSS) - Fork of Quakespasm that can run at higher frame rates than 72FPS without breaking physics.
- TASQuake - a port which allows to record inputs for tool assisted speedrunning (TAS) as .qtas files.
FTEQW - Source port focused on standalone game development. Notably includes clean-room implementations of GoldSrc file formats (BSP, MDL, WAD3, HLSPR), being used for clean-room reverse-engineered ports of 
Counter-Strike 1.5 (as 
FreeCS) and 
Half-Life Deathmatch (as FreeHL). Actively maintained.
Bugs/Limitations
Note:The original version (except Enhanced) of the game does not come with music due to various reasons:
- The GOG version originally ships the game soundtrack in .ogg format. It was removed due to legal reasons.
- The Steam version does not ship with the game soundtrack. However users can insert the original game disc in order to restore music playback.
Bug:Overbright lighting (as found in the original software renderer) was broken on GLQuake with no options to re-enabling it via any command, which makes the color less saturated and lighting much darker. GoldSrc originally fixed this in its OpenGL renderer (disableable with gl_overbright 0, but it was broken again in an update that added multitexturing support, then later fixed again with HL's 25th anniversary update. Details for this bug on GoldSrc can be found on it's page about the engine itself. Modern source ports fix this, via a
gl_overbright command, like GoldSrc.
Confirm:Does this discrepancy exist in Quake 2? It's probably fixed in IdTech 3, as that has r_overbrightbits (which works a bit differently than Quake and GoldSrc).Bug:Fullbright texels are broken in GLQuake[Elaborate?].See also
