You can generate and listen to full tracks at soundraw.io without signing up at all. A free account adds one thing: the ability to favourite a track and find it again later, under Favorites in the account menu.
The paywall is the download, not the music. Soundraw's help centre puts it plainly — creating songs is free, but "downloading and using the tracks require a subscription to one of our plans", and it says elsewhere that "there is no free trial of our license." So the honest answer on cost is: you will be paying before any file reaches your computer.
Which plan depends on what you are making. Creator, a monthly plan that costs less per month billed annually, gives unlimited MP3 downloads for background music in your own projects. The Artist tiers cost more and are for musicians who want to release tracks; only the top two include WAV and stems — the separate instrument files, drums and bass and melody apart, so you can rework them in music software like GarageBand or Ableton — and the two cheaper Artist tiers cap how many tracks you can download each month. One oddity to check once you are signed in: the pricing page's stems answer mentions "vocals (if any)" among the files, which sits awkwardly beside the help centre's statement that Soundraw does not generate vocals at all.
Annual plans are hard to leave. The terms of service (updated 12 June 2025) say fees already paid are not refunded, and that ending a yearly plan early means paying the remaining unexpired fees up front. Start monthly and switch later if it earns it.
