Best Stem Splitter - Six Tools Compared for Custom Backing Tracks
We build one of the six tools below, so let us be straight: the best stem splitter depends on the job. Here is what each tool costs as of July 2026, where it runs, and where it wins.
How We Compared These Tools
The disclosure first: StemSplitterAI is our stem splitter, and this page lives on our site. So we wrote the kind of comparison we would trust: one that names the places where other tools win.
We compared six popular tools on pricing, free access, setup effort, and what you can do with the stems after separation. Each one is the best stem splitter for someone. Prices are a snapshot as of July 2026, so confirm current rates before you buy.

Six Tools, Six Honest Verdicts
Where each tool earns its place, including the ones that beat us.
StemSplitterAI Ours
Best for custom backing tracks in the browser
Our stem splitter runs in the browser and splits any song into vocals, drums, bass, and instruments, with a stem player to solo, mute, and rebalance each part before you export a custom backing track. The free trial processes up to 5 minutes and plays the complete result before signup. Minute Packs start at $1.99 one time, paid minutes never expire, and the Unlimited Plan is $9.99 per month. Honest limits: we are the newest tool here, and there is no mobile app.
StemSplit.io
Best for DJ prep and API workflows
StemSplit.io is the tool most similar to ours: browser-based, with per-minute credits at $0.10 to $0.20 per minute as of July 2026. Its real edge is DJ prep. BPM and key detection, Camelot notation, and Rekordbox export speed up set building, and it ships a REST API. Two caveats from our research: we saw different stats quoted across its pages, and its six-stem mode sets higher expectations for piano and guitar splits than current models usually meet.
Moises
Best for app-based daily practice
Moises is the strongest brand here, built as a practice app rather than a one-off web tool. If you rehearse on your phone every day, the app ecosystem is the real draw, and the subscription, around $40 per year as of July 2026, is reasonable for daily use. The catch: a year of subscription for one karaoke track is a bad trade, and musician forums push back for exactly that reason.
LALAL.AI
Best for an established, polished web experience
LALAL.AI is one of the most established web stem splitters, with a refined interface and a deep library of guides. It runs on paid plans as of July 2026; check their site for current tiers. It is a safe, mature choice. For a single song this weekend, a free tool or a small one-time pack will usually cost less.
UVR5 (Ultimate Vocal Remover)
Best for the free quality ceiling
UVR5 is the honest answer when someone asks for the best free stem splitter and quality is the only measure. It is open source, runs separation models locally, and hobbyists treat it as the benchmark. The trade is effort: you install it, results depend on model and settings choices, and you want a capable GPU. If that sounds like fun rather than friction, many hobbyists find UVR5 matches or beats paid web tools at zero cost.
vocalremover.org
Best for a quick free vocal cut
vocalremover.org does one job, free, in the browser: split a song into a vocal and an instrumental. No account, no install, no cost, and for a fast karaoke cut it is hard to argue with. It focuses on that quick split rather than a multi-stem workflow, so when you need drumless versions or a custom mix, you have outgrown it.
