Need for Speed ProStreet (2007) in a Browser

Experimental WIP · 1 project source · checked 2026-11-03

ProStreet, released in 2007, is the track-day game: closed courses, sector times, and a different tone from the blacklist or the canyons. Reddit threads asking how to play it in a browser are real demand. The only project in these sources is PortSpeed, repository OtariTB/PortSpeed, created 31 Oct 2026 and still pushing on 3 Nov 2026.

The repository describes an ahead-of-time recompile and asks for ProStreet PC version 1.1. No license file was recorded. One source is not enough to call it playable. I am not embedding a screenshot that would make a work in progress look like a finished race.

Until a second source — a news story, a video of a full event, or a hosted page — shows a race finishing, the games table stays on “experimental WIP”. The nearest finished browser race is Most Wanted 2005 or Carbon, and neither one is a ProStreet handling model.

Evidence for this browser status

PortSpeed documents its implementation progress; it is the single source for those engineering claims.

What the repository milestones mean

The public README describes static translation from the original PC executable into C and WebAssembly. It also lists active startup blockers. That is engineering progress, rather than a consumer play destination. The source’s own requested game version applies to builders; it is not a download this guide can supply. Race completion, save compatibility, phone support and online features stay unspecified unless the project publishes evidence for them.
