About SimpleSmartRadio

SimpleSmartRadio is an independent browser and native iOS client for the community-maintained radio-browser.info directory — a public, volunteer-curated database of 50,000+ internet radio stations across 200+ countries. We don't own or license the stations; we index them, enrich them with AI-generated metadata for easier discovery, and let you play them directly in your browser. No account, 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, writes a one-sentence English and Dutch description, detects broadcaster-type, and flags platform-operated aggregator stations we choose to drop. The pipeline covers 55,000+ 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.

Add or submit a station

Station submissions go directly to the source directory. Visit radio-browser.info/add to add a new station — it will flow into our catalog automatically on the next refresh cycle.

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 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. We monitor for abuse and will throttle if usage gets bursty. See the developer page for endpoints and example calls.

iOS app

For Sonos owners: a native Swift app for iOS that turns your iPhone into a remote for your Sonos system. Tap a station — the speaker, not your phone, fetches the stream over the local UPnP protocol. Lock-Screen / Dynamic-Island Live Activity, drag-to-group speakers, and a 9-language UI (NL · EN · DE · FR · ES · IT · PT · PL · TR).

The iOS bundle is a curated subset of 23,500+ stations — only those confirmed to play on Sonos, with platform-aggregator brands and broken streams stripped. The full 55,000+ catalog stays browsable here on the web.
