Tools for musicians, built by one of them.
I'm Julien — developer and musician, guitar first. I build the practice software I need, use it every day, and share it when it's good enough to be useful: a composition assistant, an arpeggio trainer, and a sight-reading gym.
The tools
Three tools and a butler.
Each one covers a different part of a musician's day: writing, drilling, reading — and, soon, deciding what to play next. Small, honest software — no ads, no engagement traps.
Arpèges
Drill
A one-tap arpeggio trainer for guitar. Pick a preset, the fretboard lights the shape, go. Offline, no account, no ads — just the reps.

Sight Reading Gym
Read
A daily sight-reading gym for guitarists. Fresh études every day, your mic listens while you play, and you see exactly which frets and rhythms need work.

Edgars
Practice
A practice butler for musicians who gig solo — it answers what to play next in about three seconds, and it makes every answer honest.

Why a chameleon builds music tools
Webeleon started as a web workshop — the chameleon adapted to whatever clients needed. These days it adapts to something I care about more: music practice.
Every tool here exists because I wanted it for my own practice, couldn't find it done right, and built it. I use all three daily.
— Julien, Webeleon
Built from need
Each tool solves a problem straight out of my own practice log, not a market analysis. If I stop needing it, I say so.
Dogfooded daily
I practice with these tools every day. Rough edges get found by me before they ever reach you.
Small & honest
Offline-friendly, no ads, no dark patterns, accounts only where they earn their keep. No company behind it, no investors — just one musician who codes. Free while a tool is a prototype.
