Fretboard Lab license

Fretboard Lab License

Fretboard Lab uses a simple desktop license model designed for individual users, small teams, and specialist workflows that do not need a heavy account system.

A typical license is activated online inside the desktop application with the purchase email and license key. The application may store an activation record on the local machine so the tool can continue working without asking the user to sign in every time.

If the software supports offline use, the local activation state should remain usable for a reasonable period. If the machine is replaced, reinstalled, or blocked by a corporate network, contact support with the purchase email and a short description of the issue.

Do not share a license key publicly. If a key is exposed, disabled, or used on the wrong machine, support may need the purchase email, product name, operating system, and activation error message.

Before activating Fretboard Lab

Type Cmaj7, Am7, or I-V-vi-IV and explore playable fingerings sorted by position, span, open strings, and difficulty across standard and alternate tunings.

The Community path is listed as Free, which makes it suitable for checking the installer, the local workflow, and the files you expect to use before committing to a paid seat.

  • Chord parsing and voicing generation: Enter standard chord symbols (Cmaj7, Am7, Dm7b5) or roman numerals (I-V-vi-IV) and generate multiple playable voicings from the guitar-core engine.
  • Fretboard visualization and sorting: View voicings on an SVG fretboard with finger numbers, muted/open markers, and position labels. Sort by position, difficulty, span, or open string count.
