Fadr Review, Pricing & Alternatives (2026)

Fadr is a cloud music technology service operated by Pebble LLC, doing business as Fadr. It analyzes uploaded songs and returns separated audio parts, MIDI, chord progression, key, and tempo. Its Create area also includes Remix, Siren, and DrumGPT. Basic is free for life, while Plus adds higher quality separation and detailed outputs. The available materials do not state a launch year, employee count, user count, or funding figure, so those details are omitted. Fadr targets DJs, producers, remixers, educators, and developers working with existing recordings. It is delivered through a browser, with a DAW plugin for Plus subscribers and an API for programmatic processing. The service is cloud-based rather than self-hosted, so uploaded audio and generated files use Fadr infrastructure.

A typical workflow begins by uploading a song, waiting for processing, reviewing results, and downloading selected outputs. The Stems page accepts WAV, MP3, M4A, AAC, AIF, and FLAC files smaller than 200 MB each. Stems appear first, followed by key and tempo, then MIDI, allowing users to retrieve completed results progressively. Basic separates vocals, melodies, drums, and bass. Plus adds detailed vocal, drum, and melody divisions, including lead vocals, background vocals, kick, snare, piano, guitar, strings, and wind. Remix changes key and tempo while maintaining synchronization, reducing manual alignment work. The plugin offers Live, Record, and Upload modes inside compatible DAWs. Siren creates playable instruments from words or voice, while DrumGPT creates playable drum kits from words.

Fadr describes capabilities rather than naming a foundation model or publishing model versions. Its current Stems functionality combines source separation, MIDI extraction, chord detection, and key and tempo detection. Plus advertises Pro Stems, 18 stem types, lossless 32-bit WAV downloads, one-hour uploads, unlimited storage, Siren, DrumGPT, and the Stems Plugin. The plugin supports macOS through VST3 or AU and Windows through VST3, for major DAWs supporting VST3. The API returns primary stems, MIDI for applicable parts, chord progression data, key, and tempo. Fadr publishes no dated 2025 or 2026 release notes, named model updates, independent benchmarks, or version history. Therefore, current and future release claims beyond listed features cannot be verified here.

Fadr Basic is free for life and includes unlimited stems, remixes, and DJ sets with high-quality MP3 downloads. Basic uploads are limited to songs of up to 10 minutes and files below 200 MB. Plus costs $10 monthly or $100 annually, raises uploads to one hour, and adds Pro Stems, 18 stem types, 32-bit WAV downloads, unlimited storage, plugins, and the highest-quality separation model. API access requires Plus. The Create Stem Task endpoint costs US$0.05 per minute of audio and includes up to $10 in API credits with each subscription payment. After credits reach zero, usage accumulates in the API balance; billing occurs when the balance exceeds its threshold or at renewal under the documented rules. API files remain in cloud storage.

Important limits include possible separation artifacts, no published accuracy benchmark, cloud processing, and user responsibility for recording and composition rights. The terms also restrict some commercial uses of the site. Moises is a direct alternative for song separation, with six stem types listed in Fadr's comparison, plus chord, key, and tempo features. LALAL.AI is another cloud splitter, listed with ten stem types and a DAW plugin, while StemRoller provides another stem-separation option. Fadr's differentiators are MIDI extraction, chord data, remix controls, 18 advertised stem types, and an API. Those advantages do not establish superior audio quality, and its cloud requirement excludes teams needing on-premises processing. Pick Fadr if you need structured musical outputs and DAW access from existing songs; choose competitors for different separation workflows or deployment preferences.
