In the second half of 2026 a wave of new open-source music studios appeared, each modelled on the workflow of a commercial one and most of them written from scratch in Rust. This page lists the nine we know of, what each is modelled on, who makes it, its licence and how far along it says it is. Two of them compile to WebAssembly and run on this site; the rest are desktop programs you download from their own pages.
In the style of Pro Tools
Edit and Mix windows, comping playlists, automation modes, surround panning, CLAP plugins. Part of ArtCraft's family of clean-room "Craft apps" in Rust.
Runs on this site (demo session)
In the style of FL Studio Mobile
Touch-first studio written from a specification of the original's behaviour. Opens and saves .flm songs and .flp projects; hosts VST3, VST2 and CLAP plugins on the desktop.
In the style of Logic Pro
Tracks area with MIDI and audio regions, library, inspector, piano roll, mixer and a built-in synth, in Rust with egui. Reads EXS24 and SFZ sampler instruments and has begun reading .logicx project bundles. Plug-in hosting and Live Loops are still on its roadmap.
In the style of Ableton Live
Session-style clip launching with quantisation plus a linear arrangement, in Rust. Opens, plays and renders Live Sets (.als) you made yourself, with real-time time-stretching; CLAP and VST3 plug-ins run sandboxed in a separate process.
In the style of Ableton Live and Bitwig Studio
A session matrix for scene-based clip launching and live looping beside linear composition, in Rust, with wavetable and spectral synths.
In the style of FL Studio (desktop)
Pattern-based arranger with a performance mode, a freely routed mixer with delay compensation, automation clips, time stretching, 29 built-in plugins (also usable as VST3 and CLAP elsewhere) and hosting for CLAP, VST3 and VST2. Honeydew borrows its plugin and FLP code.
In the style of FL Studio, with an Ableton-style clip grid
Channel Rack, Piano Roll, Playlist and Mixer in C++20 and JUCE. Imports .flp projects, opens and saves Ableton Live 11 and 12 sets, imports .flm; ships its own versions of many FL Studio native plugins and hosts VST3 and CLAP.
In the style of FL Studio
Pattern, audio and automation clips on free lanes, 14 built-in plugins, VST3 effects. Its own README lists what it lacks: no VST instruments, no macOS build, no clip launcher.
In the style of ReBirth RB-338
Two TB-303-style bass lines, an 808 and a 909 with the mixer and effects. The project reports that its engine reproduces ReBirth 2.01's output bit for bit, tested on 1,268 songs. Opens and saves .rbs songs and plays .rbm mods; no MIDI or plugin hosting.
Everything on a card comes from the project's own repository and README as they stood on 13 November 2026: the description, the licence, the platforms and the status. We have run SoundCraft's and Honeydew's web builds, because those are hosted here and checked before each release of this site. We have not installed or tested the desktop builds of any of the nine, so nothing here is a review, and "status" is the project's own word for itself. Most of these programs are weeks or months old and several call themselves alpha or pre-alpha; expect missing features and file formats that still change.
"In the style of" means the workflow and layout a project says it follows. None of them is made by, or affiliated with, Apple, Ableton, Image-Line, Avid, Bitwig or Reason Studios, and the product names are theirs.
If your hands know Pro Tools, with an Edit window and a Mix window and editing by modes, SoundCraft is the one built around that, and it is the furthest along in mixing features on paper. If you write by launching clips in a grid, the Ableton Live way, look at Suhina, which reads Live Sets, at Hikaru OpenLive, which is aimed at live looping on Linux, and at the clip grid inside LYNX SHARE. If you think in patterns, a channel rack and a playlist, the FL Studio way, there are three desktop programs, Lemon Studio, LYNX SHARE and WAVE, plus Honeydew, which follows the mobile app and is the only one of the nine built for touch. Pro Wave is the one for Logic Pro users: a single window with the tracks area, library, inspector and mixer where Logic puts them. And OpenRB-338 is not a general studio but a faithful rebuild of one beloved instrument, the 1997 ReBirth with its two acid bass lines and two drum machines.
Most of these projects describe themselves as clean-room: the people (and, openly, the coding agents) writing the program work from public documentation, their own observation of how the original behaves, and written specifications of file formats, never from the original's code. That is the long-established way to build compatible software without copying it, the way compatible PC BIOSes and office-file readers were made. It is why these programs can open another product's project files and feel familiar without containing anything of the original. Honeydew states that it holds no code, samples, presets or artwork from FL Studio Mobile; Suhina says the same of Ableton's products and reads only Live Sets you made yourself. OpenRB-338 is the exception in method: it was rebuilt from study of the original program to match its output exactly, and it carries the original's drum sounds, which its README says plainly.
Licences differ in what they ask of people who pass the program on. SoundCraft is under Apache 2.0, which permits almost any use. The others use the GPL or the AGPL, which require anyone who distributes a modified version, or in the AGPL's case runs one as a network service, to publish their changes.
Two of the nine publish a WebAssembly build, and both run here in a sandboxed frame. Honeydew is a working studio in the tab: add a synth or a drum kit and play. SoundCraft's web build opens a demo session to look around in; it cannot open or save your own files in the browser. The other seven are native programs with real-time audio threads and plugin hosts, which a browser cannot provide, so for those the download links on their own pages are the way in.
If what you need today is simply to edit, mix or convert audio you already have, without learning a studio, the tools on this site do that in the browser: a multitrack editor, a stem splitter, audio to MIDI and the rest are listed on the tools page. And for rebuilt classics rather than studios, see Webamp, the module player and the DX7-style synth.
SoundCraft and Honeydew are catalogued on Recomp, a directory of clean-room, decompiled and reimplemented software that records each project's method, licence and whether you need the original; the others were found on GitHub. If you make or know a project that belongs here, tell us through the contact page.
Three new projects follow its clip-launching workflow: Suhina (Rust, GPL, reads Live Sets, pre-alpha), Hikaru OpenLive (Rust, AGPL, Linux) and the clip grid in LYNX SHARE (C++, AGPL). All are young; check each project's own status.
Pro Wave is an alpha-stage DAW in Rust laid out like Logic Pro, for Windows, macOS and Linux, under the GPL.
Lemon Studio, LYNX SHARE and WAVE follow the desktop program's pattern workflow, and Honeydew follows FL Studio Mobile. Honeydew runs in the browser on this site.
SoundCraft, from ArtCraft, is a clean-room workstation in Rust with Edit and Mix windows, under the Apache 2.0 licence. Its web build runs a demo session on this site.
Two: Honeydew, which is a working studio in the tab, and SoundCraft, whose web build opens a demo session. Both are hosted on this site. The others are desktop programs.
Only the two web builds hosted here. The descriptions of the desktop programs come from their own repositories as of 13 November 2026.
