Audiotool's complete rebuild supports simultaneous multi-user sessions across any device, and opens the platform to developer- and creator-built instruments and tools via a new open-source SDK.
Audiotool has launched version 3.0 of its browser-based DAW, rebuilt from scratch to support real-time multiplayer music creation across web browsers and tablets, with native mobile apps on the way.

Multiple creators can now work on the same project simultaneously from any device, with Audiotool stating it offers the lowest latency of any online music tool. The platform has built a large following among gaming communities (holding partnerships with the Esports World Cup and Esports Nations Cup), and those users are already used to the format: drop in, collaborate with whoever’s there and make something.
“Music’s past was highly social. So is music’s future,” said Andreas Jacobi, co-founder and CEO of Audiotool. “We reimagined Audiotool from the ground up to serve that future and help music break away from today’s fragmented, gated production ecosystem.”
NEXUS is an open-source SDK included with 3.0, allowing musicians and developers to build instruments, effects, visualisers, music games, educational content and hardware-connected apps directly into the platform. Low and no-code development tools are included, so it’s not limited to people with a programming background. NEXUS also supports AI integration via MCP and Context I/O, connecting a creator’s preferred LLM to Audiotool. Launch partners include Splice, Ujam, BandM8 and Fraunhofer, Europe’s largest applied research organisation.
“Think Google Docs meets a creative sandbox like Fortnite or Minecraft. The DAW becomes a platform where creators can build, experiment, and make music together.”
Audiotool has been working on cross-device music collaboration since 2010, when it launched one of the first browser-based DAWs running on Flash. A full HTML5 rebuild followed in 2017, and version 3.0 is the first complete rewrite.
“I’ve spent most of my life in studios, and the thing that got in the way of creativity was almost never the people in the room. It was the software,” said co-founder and producer Daniel Rowland. “Audiotool 3.0 takes that wall down.”
Musicians and developers can build with NEXUS now through Audiotool’s Let’s Build! Hackathon series, running through August 2026, with partners including BBC’s Research & Development department and Music Hackspace. An in-person event has already taken place as part of Berklee’s AIMS Summit.
