A one-person workshop

Tools for musicians, built by one of them.

I'm Julien — developer and guitarist. 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, one practice.

Each one covers a different part of a musician's day: writing, drilling, reading. Small, honest software — no ads, no engagement traps.

Homechord
Compose

A composition assistant for chord progressions. Sketch a progression, hear it instantly, swap chords with smart suggestions, then train your ears on what you built.

The workshop

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.

Waitlist
