Radiant Optimizer Full Game List — Browser Games You Can Play Right Now
This site is not the Windows desktop performance optimizer at radiantoptimizer.app. This is a community-maintained list of browser-playable game ports.
Sources reviewed . These 16 entries cover ports, demos and native browser games; they are not all verified as entries in the original X thread. “Playable” means the project describes browser play, not that we completed a gameplay test. Setup and availability can change.
Free may mean a demo or shareware episode; full games may still need your files. Embedding is listed only with explicit permission, not inferred from an iframe loading.
Showing all 16 entries.
No entries have confirmed embedding permission. Open the original project sites instead.

FAQ
Is this the same as radiantoptimizer.app?
No. This is an independent browser-game directory. It does not distribute a Windows optimizer, and the listed games run on separate project sites.
What does "requires your own game files" mean?
The browser engine does not include the commercial game's data. You must provide the files requested by the project from a copy you own; this site supplies none.
How many games are on this list?
This page has 16 project entries, including two Half-Life-related frontends, demos, and unconfirmed entries. That is not 16 distinct full games or 16 completed gameplay tests. The older homepage has a broader catalog.
Does GTA 5 work in the browser?
GTA 5 is not on our verified browser game list. GTA: Vice City has a documented browser engine requiring your own files; it is a different game.
Reddit discussion
One directly relevant discussion was verified in r/skate3 during this October 2026 review. The author links a separate clean-room browser version and discusses the Rust rewrite. This is a project report, not evidence that every port runs well.
“I made a version of skate 3 on the browser”
Source: u/andrewnakas in r/skate3: skate 3 on browser, reviewed . The exact posting date could not be established from the available page.
We do not have enough verified discussion to summarize a Reddit consensus about loading failures, school Chromebooks or takedowns. Check each project's requirements and use the browser capability check as a starting point; feature support alone does not prove a game will run.
