Music production has always been more collaborative in theory than in practice. Two people want to work on the same track; one owns Ableton, the other doesn’t, the sample pack lives in the wrong cloud folder, and the session dies. Audiotool has spent sixteen years arguing that the browser fixes this. With Audiotool 3.0, out July 8, it has rebuilt the whole thing to prove it.
The new version is a ground-up rewrite of the company’s free, cloud-based DAW, bringing real-time multiplayer production to browsers and tablets, with native mobile versions promised. The more interesting half of the announcement is NEXUS: an open-source SDK that lets musicians and developers build instruments, effects, visualisers, music games, educational tools and hardware-connected apps directly into the platform.
From product to platform
Most DAWs ship with a fixed toolset and a plugin format controlled by the vendor. NEXUS inverts that. It is AI-enabled by design, using MCP and Context I/O to connect a creator’s preferred large language model to the session — which, depending on your temperament, is either the obvious next step for music software or the beginning of the end of it.
“Think Google Docs meets a creative sandbox like Fortnite or Minecraft,” said Andreas Jacobi, co-founder and CEO. “The DAW becomes a platform where creators can build, experiment, and make music together.”
Launch partners include Splice, Ujam, BandM8 and Fraunhofer, Europe’s largest applied research organisation and the institution that gave the world the MP3. That last name matters more than the others: it signals that Audiotool wants NEXUS treated as an audio standard, not a hobbyist plugin store.
The gaming crossover
Audiotool’s framing leans hard on the overlap between gaming and music communities — drop into a session with your squad, or collaborate with strangers. It is not idle marketing: the company has a multiyear partnership with the Esports World Cup and a new one with the Esports Nations Cup. Its user base skews toward people who arrived from games and stayed for the beats.
The company has history here. It shipped one of the first online DAWs in 2010, running in Flash, then rebuilt it in HTML5 in 2017. Version 3.0 is the third act of the same argument, made with better latency.
The claims worth checking
Audiotool describes itself as the only free, cloud-based, ultra-low-latency DAW supporting third-party plugins at scale, and claims the lowest latency of any online music tool. Both are the sort of superlative that a browser-based product should expect to be held to, and neither comes with published numbers. Real-time multiplayer audio over the open internet is a hard problem; “lowest latency online” is a narrower crown than it sounds.
Nor is an open SDK the same as an ecosystem. NEXUS only matters if developers actually build with it, and the graveyard of open plugin platforms is well populated. Audiotool is trying to seed that with its Let’s Build! hackathon series, running through August 2026 with partners including BBC Research & Development and Music Hackspace.
Still, the strategic logic is sound. Lowering the barrier to entry doesn’t lower the ceiling, as co-founder Daniel Rowland puts it. If a generation of producers learns to make music in a tab, the company that owns the tab is in an interesting position.
