Beats: Web-based drum machine inspired by Pocket Operators

What it does

Beats is a web-based drum machine that lets users create and arrange drum patterns on a 16-step sequencer. Users can add multiple instruments, toggle individual steps on and off, adjust tempo between 60 and 200 BPM, mute instruments, and play back their patterns. Beats can be saved locally, loaded from previous sessions, deleted, and shared via URL with others.

Who it is for

The tool targets musicians and producers who want a simple, browser-based way to experiment with drum patterns. It appeals to fans of Teenage Engineering's Pocket Operators who are familiar with grid-based beat sequencing. The low barrier to entry—no download or login required—makes it accessible to casual users experimenting with rhythm and beat composition.

How it stands out

Beats draws inspiration from physical Pocket Operator hardware but removes the hardware constraint by moving the experience to the web. The interface emphasizes simplicity over feature complexity; the creator explicitly positioned it as a beat experimentation tool rather than a full sequencer. The 16-step grid is approachable for beginners while remaining familiar to Pocket Operator users. Built with Tone.js for sound synthesis and Stimulus.js for interactivity, the application includes a shareable URL system for beat distribution, lowering friction for collaboration and discovery.

What a founder should check

A founder building a competitor should verify three things. First, examine the existing landscape of web-based drum machines and DAWs—tools like Splice, BeatBox, and various open-source sequencers already occupy this space. Determine what share of the market is addressable by a free, simple alternative and whether users actually switch between tools or stick with their first choice. Second, assess switching costs: many musicians invest time learning a tool's workflow and may resist moving to alternatives. Check whether Beats has meaningful retention or if users bounce quickly. Third, investigate Teenage Engineering's position and whether the Pocket Operator aesthetic remains a lasting draw or a passing trend. Understanding whether users perceive this as a faithful companion tool or a diluted alternative will inform positioning decisions.
