Follow the source trail.
A shared list is a starting point. The project itself is the source for what you need to play.
Where this list comes from
RadiantOpti shared a browser-game post on 8 October 2026. Its reply contains 25 destinations, including fan projects, file-import ports, a broader directory and an archived website.
Original post · The complete links reply
We read that reply directly on 10 October 2026. The 25 original destinations remain separate from our additional discoveries. Entry order follows the reply in the original-list collection.
What our labels mean
- Browser start: the reviewed project describes a browser launch without a user game-file import. A large first download may still be required.
- Own game files: project instructions explicitly request game data from your own copy.
- Check project: requirements are not sufficiently documented or confirmed in our review.
- Link changed: the visible destination differs from the expected game entry.
- Archive: a historical page, with working gameplay unconfirmed.
Reviewed does not mean play-tested
“Project page or documentation reviewed” means the launch page or relevant instructions were read. We do not claim every game completed a launch, every input works, or every server is available. Mobile and gamepad filters require explicit project evidence. An empty support field means unknown, not unsupported.
Corrections to the original labels
The “Unreal Tournament” destination at ut.pieter.com identifies itself as Urban Terror. The Global Terror destination opens a portal, so its Skate Rust game is not confirmed. The GTA 5 item is a Wayback snapshot, not a verified live GTA V service.

Independent directory
We are not RadiantOpti, Radiant Optimizer’s Windows software company, or the publishers of these games. Radiant Optimizer’s PC software website describes a separate product. This directory does not distribute commercial game assets or operate linked game servers.
Reference research included radiantoptimizer.net. radiantoptimizer.org timed out during our review, so no claims about its current interface or features are made.
