SSS Suite is an independent software studio. We make a small number of products and keep them sharp: a practice companion for musicians that runs in the browser, and a fast file manager for Windows.
Practice any song in your browser.
Change the key, slow the tempo, loop the hard part. Pitch shift, speed control, A-B loop, EQ and reverb work on YouTube and on any site that plays audio. Free to use with no account and no ads. Pro adds extended pitch range, formant preservation and more.
A fast file manager for Windows.
Built with Rust for speed. Infinite tabs, dual panes, instant preview, a duplicate finder and a disk analyzer in one window. Try it free for 7 days.
SSS Suite is a small studio making software for people who practice, build and organize. Every product starts as a tool we needed ourselves, and ships when it is good enough to rely on.
We keep products light, ask for an account only when a feature truly needs one, and support what we ship for the long run.
SSS Suite was founded in 2026 in Korea. SSS Explorer has been in public release since early 2026, and Site Transpose has been on the Chrome Web Store since July 2026.
