About SimpleSmartRadio

A curated directory of publicly-available internet radio — search, browse, and play in your browser. No account, no ads you did not consent to, no audio proxy (your browser connects straight to the station).

SimpleSmartRadio is a product of Simple Smart Company.

Where the catalog comes from

We stand on top of open community data:

  • Station list — radio-browser.info, the volunteer-maintained directory (~50,000 stations across 200+ countries).
  • Long-tail additions — the public Icecast YP directory plus a small AI-driven discovery pipeline that finds Sonos-playable streams not yet in radio-browser.
  • Enrichment — each station is run through a Claude prompt that normalises genres to a closed 49-term vocabulary, writes a one-sentence English and Dutch description, detects broadcaster-type, and flags platform-operated stations we choose to drop (iHeart, TuneIn). The pipeline covers ~32,000 stations today.

Open data

The catalog data — station list, genres, descriptions, all enrichments — is open. Query it directly via our public API, no key required. Built on open sources, given back open.

What we built on top

  • A static Next.js site on Cloudflare Pages for browse + search.
  • A Cloudflare Worker (api.simplesmartradio.com) that runs Elasticsearch-backed search, returns station detail, and receives takedown reports.
  • A SQLite bundle (~12 MB, 35,000+ stations, schema v1) that ships with our native iOS app for offline-first on-device search.

Public API

The search API is free to use while we figure out real usage. No key required, rate-limited to 60 requests per minute per IP. See the developer page for endpoints and example calls.

iOS app

For Sonos owners: a native Swift app ships the bundled catalog and plays any station straight to your speakers over the local UPnP protocol. Native Android version is next.
