Been heads down on this for a bit and I'm genuinely hyped to share it 🎸

Jamly - everyone deserves an instrument 🎸🎹🥁

I always wanted to learn guitar. I just never wanted to buy one. So instead of buying one, I built it

Turns out tools that let you play piano off your keyboard already exist, but why does literally none of them feel like an actual instrument, something worth touching? 🤔

That question turned into Jamly, built for the Flowstep Challenge - guitar, keys, and drums, played entirely off the keyboard you already have. Free. No login. Nothing to download.

🎯 What it does

🎸 Guitar - six strings, live. Fret with your fingers, strum with space, and the string actually rings out and fades, the way a real one does

🎹 Keys - two full octaves, playable with both hands, notes fading in over 300ms

🥁 Drums - five pieces, snappy 150ms hits that feel percussive, not laggy

Guided Play - real songs, chord by chord, at your pace, ending in a jam-ticket recap screen instead of a plain checkmark

Upload your own chords and play your own song, your way

✨ How Flowstep made it possible Every screen was designed in Flowstep - including the three instruments themselves, down to the guided-play animations. Getting the instruments right took a few honest misses first: an early pass leaned on a reused reference photo, then a stock image standing in for it, then flat shapes with no real depth. The actual fix was staying in Flowstep and iterating hard, screen by screen, until the material and depth genuinely looked right

Claude Code was connected straight into Flowstep through its MCP server, and that connection did double duty: first, prompting and refining Flowstep's own design tools until the instruments hit real fidelity; then same connection, building and shipping the actual live site

This was never really about a cheaper guitar. It's a bet that the only real gate between curiosity and actually playing was ever the price of admission, and once that's gone, it's just you, deciding if you want to keep going. 🎶 🎨 Flowstep file: Jamly Design
