The 14 Best Browser MMOs In 2021

The beauty of browser MMO games is that they run on practically any computer that doesn’t belong in a museum. Many of these games offer a downloadable client so you can enjoy a more stable experience. Don’t worry, as the client is very small and won’t hog your computer’s resources.

So, without further ado, let’s check out some of the best browser MMOs.

Would have loved to have seen some love for Mirage Online Classic on this list! I've been playing it for a few months and it's pretty addicting. Definitely niche, but it is consistently updated and not as cookie cutter than most modern money grab MMOs. Hope Adam gives a look and considers an honorable mentions section.

Jade Goddess doesnt deserve to be on this list. Russian publisher which cares just about getting cash but they dont fix the game EVER. (90% of the events are not working by half year, and they say its because daylight saving time the reason but never fix them)
