Values

Free and open source

Everything here is free to access and use. The code is MIT, driver and horn specs are CC0. Enclosure entries carry the original designer's license, open or proprietary, catalogued honestly without exception. No paywall, ever.

No tracking, no accounts, no cookies

No accounts means you never sign up, never get profiled. No cookies means no consent banners, no cross-session tracking. The only data your browser stores is localStorage for your theme and stack state, it never leaves your device. No fingerprinting, no third-party trackers.

Anonymised, aggregated statistics are collected via Cloudflare Web Analytics, details on the privacy page.

Take it, run it, share it

Fork the repo, run your own instance, build a regional mirror. The code and data are designed to port: no proprietary dependencies, no cloud services you can't replace. Enclosure plan files carry their original designer's license, check it before mirroring those.

Knowledge as protection

Sound system culture has always lived under threat: gatherings banned, equipment seized, organisers criminalised. It is the people, not the website, who bear that risk. Keeping this knowledge free, open, and widely distributed means builders and organisers are less dependent on any single source that can be taken away. Anyone can have it. Anyone can pass it on.

Collectively built

The catalog grows through contributions. Submit a design, correct a spec, add curves from a real measurement: every change is a pull request against public data. The format is deliberately simple (JSON specs, CSV curves, MDX build notes) so there are no barriers beyond git.
