Quake III Arena in Browser: Guide & Verified Status

Quake III Arena has documented browser-port technology in QuakeJS, but the candidate host was unavailable in our check. The quakejs.com address returned an invalid SSL response rather than a running game. QuakeJS’s own repository provides useful details about ioquake3, Emscripten, content servers, and network limits. This page reports that project evidence while withholding a Play button and any claim that a match was tested.

The candidate quakejs.com host returned an invalid SSL error (526) during our check. No working Play link is published and gameplay remains unverified.

External entry: not verified

Last checked: October 9, 2026 · Scope: candidate host SSL response; gameplay not reached.

No verified entry available.

No direct Play link is published for this candidate. Project documentation below, when available, is evidence about code or licensing rather than a substitute game host.

How to play Quake III Arena: four checks

  1. Start with the source status. There is no verified direct address for this Quake III Arena candidate. Read the evidence below before seeking a host; this page cannot offer a working Play link.
  2. Read the loader rather than guessing a wait time. The candidate quakejs.com host returned HTTP 526 (invalid SSL) in the recorded check. No map, frame rate, latency, or loading time was measured. A browser app can transfer files even when no installer is needed. No 10–30 second estimate is established for this entry. Treat the documented server architecture as configuration information, not a ready public session. A content server can describe assets while a game host remains unavailable, as in the recorded SSL check.
  3. Before attempting a future working host, read which content server, maps, and mods it supports. QuakeJS uses a separate content server, and server configuration determines available assets. The previously checked quakejs.com host cannot currently serve as a verified entry.
  4. No running Quake III Arena browser session or implementation-specific control screen was checked. Do not substitute the original game’s input mapping.

What to expect

We’re playing / version
QuakeJS is a JavaScript port of ioquake3 documented by the inolen/quakejs project. A project README establishes lineage and network design, not the current candidate host’s service status. The SSL failure prevents a claim about working matches, offline bots, or browser rendering speed. No gameplay session has been verified.
Performance
The candidate quakejs.com host returned HTTP 526 (invalid SSL) in the recorded check. No map, frame rate, latency, or loading time was measured.
Multiplayer
The project documents WebSocket networking and server setup. Native and web builds cannot directly interoperate under that design; we have not joined a working match.
Mobile
No phone or Chromebook session was checked for Quake III Arena. A desktop title does not establish browser or touch compatibility.

About this browser version

The inolen/quakejs README identifies QuakeJS as a JavaScript port of ioquake3 using Emscripten. This is stronger evidence about implementation than a cover image, but it does not make the unavailable quakejs.com host a working game.

The project separates game content into a content server. Available maps and mods depend on server support, and the base-game server setup includes accepting an EULA. Those requirements should be checked for any particular host rather than assuming the entire asset library is freely bundled.

The README also describes WebSocket networking. That design prevents direct connections between native and web builds. This is a project-reported compatibility limit, not a multiplayer session we tested; the existing host check stopped at an SSL error.

The official store description identifies the original Arena title and its competitive focus, including offline bots in the native game. Those native features do not confirm a working QuakeJS host or browser bot mode.

Engine basis
ioquake3 compiled using Emscripten; the repository describes a JavaScript port. It should not be relabeled a verified WASM build.
Release-label scope
Quake / 1999 · Quake III Arena official store description. Original launch platforms remain unverified; a current store-platform list is not a launch-platform record.
Verified original launch platforms
Not established by the checked primary sources. No platform list is inferred from a cover image.

Quake III Arena browser FAQ

Can a QuakeJS browser client connect directly to a native Quake III server?

The project documentation says native and web builds cannot directly interoperate because the web networking uses WebSockets.

Why is there no Play button for quakejs.com?

The recorded host check returned HTTP 526, an invalid SSL response. We do not label an unavailable host as a working entry.

Is QuakeJS necessarily a WebAssembly port?

The primary repository describes a JavaScript port of ioquake3 using Emscripten. We do not substitute an unverified WASM label.

Does QuakeJS include every map or mod?

Its content-server and game-server configuration determine supported assets. The documentation does not justify a blanket promise that every map or mod is available.
