Private by default
Uploads and generated stems are encrypted in storage, expire 24 hours after job creation, and are then removed by automated cleanup.
No subscription trap
Buy credits once and use them whenever. One full 4-stem download costs 1 credit.

Use current sources for every comparison
Unknown competitor details stay labeled as unknown until the provider publishes them.
Compare a free two-track result with a four-stem workflow
VocalRemover.org advertises a free vocal and instrumental split. That may be the simplest choice when those two files are enough. StemSlice publishes free and paid upload limits and separates drums and bass as well, which matters for remix editing, instrument practice, and arrangement study. The useful comparison is workflow fit, not a claim that one service wins every song.
Use one source section for an honest listening test
Upload the same lawful source and compare a dense chorus, a sparse verse, and a sustained ending. Match playback loudness before judging bleed or fullness. Different models can favor different instruments, so a single marketing sample is weaker evidence than the exact passage you intend to use.
Treat unstated limits as unknown
Competitor upload size, retention, encoding, and commercial terms can change. When the official page does not state a number, this comparison labels it as not publicly stated instead of inferring a limit from an old test. The source link and verification date make future updates auditable.
Recheck public comparisons before every material update
Competitor limits, pricing, retention, and exports can change without notice. This page therefore links to the current provider and treats details that are not publicly stated as unknown. Before changing a comparison row, record the source URL and verification date instead of copying an old search result or review.
Credits that do not expire
1 credit unlocks one full 4-stem download. Previewing, listening, and failed processing jobs do not consume credits.
