Best Guitar Chord Software 2026: Desktop Voicing Tools vs Web Chord Finders
Compare the best guitar chord software: Fretboard Lab, Oolimo, JamPlay, and fretmap.app. Covers playable voicing filters, alternate tunings, progression mode, diagram export, and desktop vs web workflow.
Web chord finders answer "where can I put my fingers for Cmaj7?" Desktop chord software answers "which Cmaj7 voicing should I actually play in this song, at this position, in this tuning?"
If you're arranging songs, teaching, or writing, the desktop approach saves hours.
What a chord tool should do
- Find playable voicings — Not every shape. Only the ones your hands can grab.
- Work in alternate tunings — Recalculate voicings for DADGAD, Open G, Drop D.
- Build progressions — See how chords connect, not just individual shapes.
- Export diagrams — PNG, PDF for lessons and charts.
The tools
Fretboard Lab ($19 lifetime, desktop)
Type a chord, filter by position and difficulty, sort by playability, switch tuning, export the diagram. Built for the arrangement workflow, not the quick-lookup workflow.
Oolimo (free, web)
The best free web chord reference. Quick lookup, clean interface. No progression mode, no alternate tuning recalculation, no export workflow.
JamPlay Chord Finder (free with account, web)
Chord lookup with lessons attached. Good for learning, not for arranging.
fretmap.app (free, web)
Interactive fretboard map. Good for exploring the neck, not for chord selection and export.
