ZipBeat is a grid-based beat sequencer powered by the Web Audio API. No installs, no accounts. Just open and start building.
What ZipBeat can do
Sine, square, sawtooth, and triangle waves. Dial in frequency and detune for each block on the grid independently.
A 10 row by 1000 column grid. Click to place sound blocks. Sounds in the same column play simultaneously, perfect for chords and layers.
A draggable playhead sweeps left to right. Pause mid-sequence, jump to start, and the playhead resets automatically when silence is reached.
Export your grid as a JSON file and reload it any time. Your full composition with every block and every parameter is stored locally.
Render your sequence to OGG or WebM audio with configurable bitrate. No server, no upload. All processing happens in your browser.
Pure vanilla JS and Web Audio API. No frameworks, no plugins, no account required. Works offline once loaded.
Open the editor and start laying down beats in seconds. It's free forever.
