This site is static, so any simple local HTTP server works. From this repository:
python3 -m http.server 8000Then open http://localhost:8000/.
The download buttons use the GitHub Releases API in the browser to resolve the latest stable Fleasion build for Windows, macOS, or Linux. If that request is unavailable or rate-limited, the buttons fall back to the official GitHub Releases page.
