100% web — even on your phone
No installs, no plugins, no native app. StaffWeaver runs in any modern browser, including the one already on your phone — most notation software still needs a desktop install to get real work done.
Sheet music, anywhere
StaffWeaver is a music notation editor that runs entirely in your browser — laptop, tablet, or phone. No installs, no plugins. Drag notes onto the staff and start composing in seconds.
Why StaffWeaver
Touch-first editing
The editor was built for touch from the start: magnetic drag-and-drop note entry that works as well with a finger as it does with a mouse.
One platform, one roadmap
Compose today, with scanning and playback arriving on the same account as we build them — one place for your music instead of juggling separate tools.
A real notation editor, live today
Touch-first, magnetic drag-and-drop note entry that keeps every measure musically valid as you work — dotted rhythms, automatic beaming, ties, and accidentals handled the way a copyist would handle them. Create a free account and be first in line as cloud-saved scores, scanning, and playback arrive.
