Updated Oct 10, 2026 · 3 links from the Radiant Optimizer list
Three Quake games from the list come from one non-commercial project on pieter.com: QuakeWorld, Quake II and Quake III Arena. All three are online deathmatch, and none of them asks for files.
This is the closest the list gets to a plug-and-play retro shooter: open the tab, click in, and you are fragging in seconds.

Quake in browser is the most plug-and-play part of the Radiant Optimizer list. Three links come from one non-commercial project on pieter.com: QuakeWorld for the original Quake, Quake II, and Quake III Arena. Each opens straight into online deathmatch with no download and no game files. You click, the browser captures your mouse, and you are fragging within seconds.
Each site labels itself non-commercial and unofficial. They are preservation-style projects that let people revisit the games that defined online shooters.
id Software released the source code of its Quake engines under the GPL: Quake in 1999, Quake II in 2001 and Quake III in 2005. That openness made Quake the most ported game engine in history, and modern ports compile it to WebAssembly so it runs in a tab. The servers host the matches; your browser renders the game and sends your inputs.
Because these are real online matches, your ping depends on how far you are from the server. QuakeWorld's prediction hides some of that delay, Quake III less so.
Two more links use engines from the same family: Return to Castle Wolfenstein in browser for objective-based World War II matches, and Urban Terror in browser for tactical team play. The Quake browser games page compares all five.
Each game has its own arsenal, and knowing it is half the battle. In the original Quake, the Nailgun and Super Nailgun are reliable all-rounders, the Grenade Launcher controls corridors, the Rocket Launcher wins most fights, and the Thunderbolt melts anyone at close range but discharges everything if you fire it underwater. Quake II adds the Chaingun, the Hyperblaster and the Railgun for precise long-range hits.
Quake III Arena has the most balanced set: Machinegun to start, Shotgun up close, Lightning Gun for tracking, Railgun for snipes, Plasma Gun for spam, Rocket Launcher as the all-purpose weapon, and the BFG10K as the rare power weapon. Picking up armor and Mega Health matters as much as weapons; good players time their respawns.
The first release of Quake sent every movement to the server and waited for a reply before showing it, which felt sluggish over 1990s modems. QuakeWorld changed that by predicting your movement locally and correcting it when the server answered. That idea now underpins almost every online shooter, and it is why QuakeWorld still feels responsive in a browser today.
These servers are multiplayer deathmatch.
No. All three load directly.
Not on these servers. They are multiplayer deathmatch only.
No. The servers stream everything the browser needs for multiplayer.
Quake III Arena if you want fast action, QuakeWorld if you want the classic feel.
