The list

  1. DOOM (Silent Space Marine)

    by id Software, multiplayer version by Cloudflare · on silentspacemarine.com

    The 1993 shooter that defined the genre: fight through Knee-Deep in the Dead, the free first episode, on your own, or start a multiplayer room and send the link so friends join you in the same game.

    Best played in a desktop browser with a keyboard; phones get an on-screen joystick

    Why it's here and what to know

    Cloudflare built this version in May 2021 to show what its network can run, with live multiplayer on top of the original game, and it uses the shareware episode id Software gave away itself, so nothing here is a pirated copy.

    Why it counts as AA: id Software's 1993 commercial PC release, and the game most shooters since are measured against. The browser build runs the official free shareware episode.

    Good to know: Only the first episode is included. Click the game first so it picks up your keyboard.

    Typical session: 5–15 minutes a level

    • first-person shooter
    • multiplayer
    • classic

  2. Quake (NetQuake.io)

    by id Software, browser port by Joe Lukacovic · on netquake.io

    id Software's 1996 shooter in full 3D: play Episode 1 on your own, from the slipgate base to the Lovecraftian castles, or join a community server for deathmatch, all in the browser.

    Best played in a desktop browser (Chrome, Edge or Firefox) with a keyboard and mouse

    Why it's here and what to know

    The most complete Quake in a browser: single player and online servers, open source on GitLab, and free with the shareware episode id Software released. If you own Quake you can add the other three episodes from your own copy; it stays on your computer.

    Why it counts as AA: id Software's 1996 commercial PC release, from the studio behind Doom. The free episode is the shareware id shipped with it.

    Good to know: Click into the game to lock the mouse for aiming; press Esc to get the pointer back.

    Typical session: 10–20 minutes a level

    • first-person shooter
    • multiplayer
    • classic

  3. Diablo (DiabloWeb)

    by Blizzard North, browser port by d07RiV · on d07riv.github.io

    The 1996 action RPG that every loot game since has borrowed from: descend beneath the cathedral of Tristram as the Warrior, clicking through demons and skeletons for gold, gear and levels.

    Best played in a desktop browser with a mouse; it also runs on phones

    Why it's here and what to know

    DiabloWeb has run in browsers since 2019 and has 2,892 stars on GitHub. Play Shareware loads Blizzard's free demo (a 50 MB download); if you own Diablo (it's sold on GOG) you can load your own copy for the full game.

    Why it counts as AA: Blizzard North's 1996 commercial PC release, which defined the action RPG. The free version is Blizzard's own shareware demo.

    Good to know: The shareware version is the Warrior and the first two dungeon levels. It's a fan-made port built on a reconstruction of the game's code, not an official Blizzard release.

    Typical session: 20–40 minutes

    • action rpg
    • dungeon crawler
    • classic

  4. Taipei Rush

    by AICodeWithMe · on taipei-rush.app

    An open-world Taipei in 3D: ride a scooter through Ximending, the night markets, Taipei 101 and the MRT stations, take on missions in the traffic, or open a room and ride with up to seven friends.

    Best played in a desktop browser with a keyboard; it also plays on phones

    Why it's here and what to know

    The biggest browser original we found: its launch post drew 59,000 likes on Threads, Taiwan's CTS News covered it, and it now has its own Wikipedia article. The same developer has added Mumbai, Tokyo, Hong Kong, London and other cities.

    Why it counts as AA: Not a studio game: one developer built it with AI tools. But it's built at AA scale, a whole 3D city with traffic, missions and online rooms, rather than a single-screen web game.

    Good to know: The developer says AI wrote much of it, at a cost of over US$10,000 in AI tokens. Its site doesn't allow other sites to show it, so it opens on taipei-rush.app; a Google sign-in is optional.

    • open world
    • driving
    • online multiplayer

  5. Urban Terror

    by FrozenSand, browser build by pieter.com · on ut.pieter.com

    A fast, realistic team shooter: pick a side and a loadout of real-world guns, then sprint, wall-jump and climb through team matches on maps like Casa, Turnpike and Abbey.

    Best played in desktop Chrome with a keyboard and mouse (the site recommends Chrome)

    Why it's here and what to know

    FrozenSand has always given Urban Terror away, and this unofficial build runs its real engine compiled for the browser, with a live server, a leaderboard and a daily match, so there are usually people to play with.

    Why it counts as AA: Not a boxed release: FrozenSand's free standalone shooter, which began in 2000 as a Quake III mod and has been polished over two decades. In scale and feel it's much closer to a retail shooter than to a web game.

    Good to know: The first load downloads the game data, which your browser then keeps. Online only, against other players.

    Typical session: 10–20 minutes a match

    • first-person shooter
    • online multiplayer
    • tactical

  6. QuakeWorld

    by id Software, browser build by pieter.com · on q1.pieter.com

    Quake's online version, built by id Software for internet play in 1996: type a name, press Play and you're dropped into an eight-player deathmatch on the classic first-episode maps.

    Best played in a desktop browser with a keyboard and mouse (a gamepad works too)

    Why it's here and what to know

    The quickest way into a real Quake deathmatch: one click, a live server with a leaderboard and a daily match, and eight people were in a game on E1M3 when we checked. It runs the free shareware data, not a retail copy.

    Why it counts as AA: id Software's own 1996 online update for Quake, which first made fast deathmatch playable over ordinary home internet.

    Good to know: Multiplayer only, against real people, so expect experienced players. Press Esc to free the mouse.

    Typical session: drop in and out any time

    • first-person shooter
    • online multiplayer
    • deathmatch

How we chose these games

We opened all 125 games listed on bitrunlog.com, a directory of browser ports and recompilations, on 26 October 2026, and kept only games that are free, start in the browser without a download or a sign-up, show no ads, and run game data their makers give away: id Software's and Blizzard's shareware episodes and FrozenSand's free Urban Terror. That rule removed most of the directory. Quake II, Quake III Arena, Return to Castle Wolfenstein and DOOM II builds load files from the retail games; GTA, Call of Duty, Counter-Strike, FIFA, Tekken and the PlayStation 2 sites run copies of commercial games; others ask you to upload your own copy, and some show ads or open pop-ups. We also opened the directory's browser originals: Taipei Rush is the one built at AA scale with real player reception; the rest were small, unfinished, or used assets ripped from commercial games. We call a game AA when a professional studio made it as a full PC or console release, or when it is built to that scale; each card says why it counts. Five of the six play inside Unfound's player, so you can try them without leaving.

Every game here was checked on Oct 26, 2026 to be free and to run in a web browser with no download. Editors are playtesting each one for a full review; scores appear once that is done.

AA games: questions people ask

What is an AA game?

AA (double-A) games are made by established studios with mid-sized budgets: bigger and more polished than indie games, smaller than blockbuster AAA releases. Very few run in a browser, so this list counts full PC releases from professional studios whose free versions now play in a tab, such as DOOM, Quake and Diablo, plus games built to the same scale.

Can you play PC games in a browser without downloading them?

Yes. DOOM, Quake and Diablo were sold as PC games in the 1990s, and their free shareware versions now run in Chrome, Edge or Firefox through WebAssembly, with nothing to install. They play best on a laptop or desktop with a keyboard and mouse.

Is it legal to play DOOM or Quake in a browser?

The versions on this list are. Each runs data its maker gave away free (id Software's and Blizzard's shareware episodes and FrozenSand's Urban Terror) on an open-source or fan-made engine. Many other sites run full copies of games like GTA, FIFA or Call of Duty without the publisher's permission; we don't list those.

Why aren't GTA, Call of Duty or FIFA on this list?

The browser versions of those games run copies of the original game files that the publishers never released for free, or ask you to upload files from your own copy, and many of the sites hosting them show ads or open pop-ups. Unfound only lists games that are free, legal and ad-free.

Which browser is best for these games?

Chrome or Edge on a desktop or laptop: Urban Terror's site recommends Chrome. Click into the game so it can lock your mouse pointer for aiming, and use full screen for the smoothest play. The first load of each game downloads its data, which your browser then keeps.

Can I play these games with friends online?

Yes. DOOM (Silent Space Marine) lets you start a room and send friends the link, Quake on NetQuake.io has community servers, and QuakeWorld and Urban Terror drop you straight onto a live server with other players.

Can I play these games on my phone?

Taipei Rush plays on phones, DOOM has an on-screen joystick and Diablo runs on a phone too, but these are PC games at heart: they are much better on a computer with a keyboard and mouse.
