10 Indie Devs Who Started with Browser Games

Some of the biggest names in independent game development built their first audiences in the browser. Newgrounds, Kongregate, Flash-era portals, and personal websites were where a generation of designers learned what worked and what failed. The names below are indie devs who released browser or Flash games before the projects most people now know them for. Each of these origins is publicly documented.

1. Bennett Foddy — QWOP and the ragdoll roots of Getting Over It

Bennett Foddy published QWOP in November 2008 as a free browser game on his own site. The game asked players to control a sprinter using the Q, W, O, and P keys to operate the runner’s thighs and calves, with predictably hilarious results. QWOP went viral, was ported to mobile, and became a Newgrounds and Flash-era classic. Foddy followed it with GIRP and other browser experiments before Getting Over It with Bennett Foddy in 2017, which carried the same difficulty-as-comedy philosophy from QWOP into a longer-form commercial release. His academic background as an Oxford philosopher gives his game design a recognizable theoretical underpinning.

2. Edmund McMillen — Newgrounds Flash to The Binding of Isaac

Edmund McMillen built his early career on Newgrounds, releasing Flash games like Aether (with Tyler Glaiel), Coil, Triachnid, and Time Fcuk through the mid-to-late 2000s. He co-created Meat Boy as a Flash game in 2008 (the basis for Super Meat Boy with Tommy Refenes in 2010), and then developed The Binding of Isaac, which launched on Steam in 2011 and built into a long-running franchise. McMillen is one of the clearest cases of a Flash developer making a clean transition into commercial indie success. His Newgrounds profile remains as a public record of the early work.

3. Toby Fox — ROM hacks, Homestuck music, then Undertale

Toby Fox is best known for Undertale (2015) and Deltarune. Before either, his public output included Earthbound ROM hacks (Earthbound Halloween Hack circulated on the fan forum starmen.net in the late 2000s) and music for the Homestuck webcomic, where his soundtracks for the comic’s interactive sections became widely shared. His “browser game” lineage is more about web-distributed games and interactive Homestuck segments than pure Flash games, but the through-line of community-distributed creative work before Undertale is clear and documented in his own published interviews.

4. Tom Fulp — founder of Newgrounds, creator of Castle Crashers and Pico’s School

Tom Fulp founded Newgrounds in 1995 and built it into the dominant Flash game and animation portal of the 2000s. His own development output includes Pico’s School (1999, a Flash game), Alien Hominid (initially a Flash game, then ported to console as a commercial title in 2004), and Castle Crashers (2008, console release through The Behemoth, the studio Fulp co-founded). Fulp is the rare case of a developer who both built the platform other indie devs launched from and built his own successful indie games.

5. Tommy Refenes — Flash collaborations to Super Meat Boy

Tommy Refenes co-developed Super Meat Boy with Edmund McMillen. Before Super Meat Boy, his early work included the original Meat Boy Flash game (2008, on Newgrounds), Goo!, and various Flash collaborations. The Newgrounds origin of the Meat Boy character is documented in the Indie Game: The Movie documentary, which followed Refenes and McMillen during the Super Meat Boy development period.

6. Daniel Benmergui — Flash experiments to art games

Daniel Benmergui is an Argentine indie developer whose Flash output included I Wish I Were the Moon (2008), Today I Die (2009), and Storyteller (a Flash prototype that later became the 2023 commercial release Storyteller). His early Flash work was distributed through free portals and his personal site, and was nominated for several IGF awards in the late 2000s. Benmergui’s trajectory from Flash to commercial release took over a decade and is documented in his own GDC talks.

7. Daniel Mullins — Pony Island and the browser-game-feel inheritance

Daniel Mullins’s commercial games — Pony Island (2016), The Hex (2017), Inscryption (2021) — owe a clear debt to the Flash-game aesthetic. Pony Island in particular plays in part as a faux-Flash-game-within-a-game. Mullins’s earlier work included Catch Monsters (a free downloadable game) and several smaller browser-distributed projects. The Pony Island Steam page and Mullins’s own interviews credit Flash-era browser games as a direct influence.

8. Petri Purho — Crayon Physics and the Experimental Gameplay Project

Petri Purho is the Finnish developer behind Crayon Physics Deluxe (2009). Before the commercial release, the original Crayon Physics prototype was distributed free and gained attention through the Experimental Gameplay Project, an online site that featured prototype browser-friendly games from a number of indie developers. Purho’s prototype work and his role in EGP made him a known figure in the late-2000s indie scene before his commercial release.

9. Markus Persson — Java applet experiments to Minecraft

Markus “Notch” Persson released Minecraft in May 2009 as a Java game that ran in the browser. The early versions were distributed through Persson’s website and played in a Java applet — meaning it was, in a real sense, a browser game in its first months. Persson had a history of earlier Java game experiments (including a game called Wurm Online with Rolf Jansson) before Minecraft. The Java applet origin of Minecraft is documented in Persson’s own writing from the period. Minecraft eventually became a downloadable client, then was acquired by Microsoft in 2014.

10. Adam Saltsman — Flash games to Canabalt and beyond

Adam Saltsman built a substantial Flash game catalog before releasing Canabalt in 2009, which became one of the most influential endless runners ever made (the inspiration for countless mobile and browser one-button runners that followed). Saltsman also developed Flixel, an open-source ActionScript game framework that many other Flash-era developers used for their own projects. Canabalt itself was originally a Flash game released to itch.io’s predecessor sites and Saltsman’s own page before commercial mobile ports. His Flash and Flixel legacy is documented across the indie game design community.

What the Flash era did for indie development

The 2005-2012 window when Flash dominated browser gaming was one of the most concentrated incubators of independent game talent in the medium’s history. Newgrounds, Kongregate, Armor Games, and personal sites gave developers free distribution, immediate audience feedback, and a community of peers iterating in public. Many of the names above credit that period directly in their published interviews and developer talks.

When Flash died — Adobe ended support in 2020 — most of those games went dark. The Internet Archive’s Flash Games Preservation project has rescued thousands of them, including early work by several developers on this list. For an active browser game from the same lineage that still runs in any modern browser, the Chrome Dino game is the closest current equivalent to the bite-size 2007-era browser game form.

Frequently asked questions

Why did so many indie devs come from Flash games?

Flash was free to develop in, free to distribute through Newgrounds and other portals, and gave immediate audience feedback. The combination meant any aspiring developer could iterate on game design with real users without funding or publisher support. Few platforms before or since have matched that combination.

Are any of these original browser games still playable?

Flash itself is dead in modern browsers, so the original Flash versions of Meat Boy, Aether, and others do not play directly. The Internet Archive’s Flash Games Preservation project has emulated many of them. Some have been ported to HTML5 by their original developers; others remain available only through emulation.

Who was the first browser game developer to make it big commercially?

By revenue, Markus Persson with Minecraft (originally a Java applet that played in the browser) is the largest example. By cultural impact, Tom Fulp’s Newgrounds work and the Behemoth’s transition from Flash to console rank near the top.

Is it still viable to start as a browser game developer in 2026?

Yes. The tools are better than the Flash era (Unity, Godot, and modern HTML5 frameworks all export to web), the distribution platforms (itch.io, the developers’ own pages, niche portals) are healthier than people think, and the audience for short web-native games remains. The path is different but the principle holds.

Did any indie devs go in the opposite direction — from console to browser?

A few. Some developers who built console reputations have released free browser-playable spinoffs (often for promotion). Bennett Foddy’s QWOP was a browser-first release that later went mobile; less common is a developer going console-to-browser as their main move.

The bottom line

The browser game era is not a footnote in the indie game story — it is the formative chapter for a significant share of the developers who define modern indie. Bennett Foddy, Edmund McMillen, Toby Fox, Tom Fulp, and the rest came up through portals, personal sites, and free distribution. The lesson for current developers is the same as it was in 2008: pick a small idea, release it for free, see what people do with it. The platform has changed; the path has not.
