Subterranea: Metal Discovery

No setup, no API key — Subterranea works the second you open it. Feed it bands you love and unearth the underground. One free dig a day; go Pro for unlimited.

You've heard the classics. Subterranea is for what's underneath.

Feed it a band you already love, and it surfaces artists you haven't heard yet — not the algorithm's greatest hits, but the ones waiting one, two, or four layers down.

DIG BY DEPTH Choose how far you want to go: • Surface — the canonical, well-known names around your seeds • Underground — recognized, but not household names • Deep — cult bands with a devoted following • Bedrock — demos, tiny labels, and buried gems

BUILT FOR CRATE-DIGGERS • Track every find: to-listen, listened, favorite, or passed • Hide bands you already know so they never resurface • "More like this" to branch off any discovery • Dig by region and scene • Your whole library lives on-device; export a backup anytime

PRIVATE BY DESIGN No account. No login. No tracking. Everything you save stays on your phone. The only thing that leaves your device is the band you type in —sent to Subterranea's service to generate your recommendations, with no name, email, or identity attached.

FREE TO START Get one dig every day, free — no account, no card.

SUBTERRANEA PRO Go Pro for unlimited digs, every depth from Surface to Bedrock, and region and scene filters. Monthly or yearly — cancel anytime. Every subscription directly supports an independent developer keeping the underground alive.

Stop replaying the same ten albums. Start digging.
