Most musician tools either cost money, require you to create an account, or bury the feature you actually need under six menus. These don’t. The tools below run entirely in your browser — no download, no login, no subscription. Open the page, use the tool, close it. That’s it.
These are the tools we built for working musicians: the ones we found ourselves needing during rehearsal, before a gig, or in the middle of a session. Every one of them is free.
Paste any chord chart, set the original key and your target key, and every chord updates instantly. It handles major, minor, 7th, maj7, sus2, sus4, dim, aug, add9, slash chords — anything you’d encounter in a real chart. Lyrics and timing marks get left exactly as they were.
A browser-based metronome and click track generator that goes beyond a simple tick. Set your BPM, choose your time signature, add accents on the downbeat, and get a steady click you can play along with or record into a session. No plugin required — it uses the Web Audio API so the timing is tight.
Build and organize your setlist in the browser. Drag to reorder songs, add keys and BPM notes to each track, and print or export when you’re done. Useful for solo performers and bands alike — especially when you’re changing the order five minutes before stage time and don’t want to rewrite the whole thing by hand.
Upload a mixed audio file and separate it into individual stems: vocals, drums, bass, and other instruments. Useful for learning a song by ear, isolating a part to transcribe, or pulling a vocal out of a track. Processing happens client-side in your browser — your audio doesn’t get uploaded to any server.
All tools run in your browser. No account, no download, no data sent to a server. Open a tool, use it, close it. That’s the whole model.
The tools handle the software side. Here’s the gear that makes the most of them in a real playing situation.
A phone or tablet mount for your music stand keeps charts and setlists visible while you play. These are the ones that actually hold position without creep:
A click track is only useful if you can hear it cleanly while you play. In-ear monitors let you run the click in one ear and your instrument in the other:
Good headphones make a real difference when you’re trying to pick out a bass line or isolate a vocal. Closed-back headphones block outside noise so you can focus on the stem:
The music software market is full of great tools that cost money, require installation, tie you to a single machine, or need an internet connection to phone home to a licensing server. Browser-based tools sidestep all of that. They work on any device — your studio computer, your laptop at rehearsal, your phone backstage. They update automatically. They don’t eat disk space or nag you about subscription renewals.
There’s a practical ceiling, of course. A browser-based stem splitter isn’t going to replace a full DAW with Melodyne and iZotope running natively. But for the quick, repetitive tasks that come up constantly — transposing a chart, generating a click, building a setlist, isolating a part to learn — a tool you can open in ten seconds and close when you’re done is almost always the right choice.
