mpump

mpump is a browser-based music production tool for creating electronic loops and beats without installation or account setup. Users compose grooves using drums, bass, synth, and Euclidean rhythm tools, then share their work as URLs that encode the full pattern, tempo, and sound selection. Recipients can open a link, hear the groove, modify it, and send it back transformed.

Designed for producers working with techno, house, acid, and other loop-based electronic genres, mpump emphasizes instant creation and collaborative remixing. The maker built it with Claude Code and released it as free, open-source software under the AGPL-3.0 license.
