Loopmaster has unveiled a browser‑based IDE aimed at livecoding music performances. The platform blends code editing, real‑time audio synthesis, and visual feedback, letting musicians compose and manipulate sound on the fly without leaving the browser. By targeting the niche of algorithmic and generative music, Loopmaster hopes to streamline the workflow that typically requires multiple desktop tools. Its open API supports MIDI input for expressive control.

Unlike traditional DAWs that rely on GUI knobs, Loopmaster’s text‑centric approach lets users script patterns, modulate parameters, and trigger samples with concise code snippets. The IDE supports popular JavaScript‑based audio libraries and includes a built‑in console for immediate debugging. Community members can share patches directly through the site, fostering a collaborative ecosystem for live‑coded sets. Export functions as standalone scripts.

The service runs entirely on client‑side WebAssembly, meaning no installation or licensing fees, which could lower the barrier for experimental musicians and educators. Early adopters on Hacker News have praised its responsiveness and low latency, suggesting it may become a go‑to sandbox for rapid prototyping of audio algorithms. Loopmaster now offers a public beta at its home page.
