SoundCraft is an open-source digital audio workstation, written in Rust, that follows the Pro Tools way of working. Open it here and you get the Edit and Mix windows, plugins, automation and MIDI, playing a nine-track demo song made entirely by SoundCraft.
The Edit window has the Shuffle, Slip, Spot and Grid modes and the Smart, Selector, Grabber, Trim, Pencil, Zoom and Scrubber tools; ⌘= (Ctrl+= on Windows) flips to the Mix window. Playlists with comping lanes, clip gain, fades and undo for everything are there too.
Ten inserts and ten sends per track, busses, aux inputs, master faders, VCAs and routing folders, solo-in-place with implicit solo, and meters with peak hold. 24 built-in plugins cover EQ, dynamics, reverb, delay, modulation, saturation and pitch.

Instrument tracks play 2 built-in instruments, a subtractive synth and a drum synth. Write parts in the piano roll with a velocity lane or by step input, then quantize and transpose them.

Breakpoint automation for volume, pan, mute, sends and every plugin parameter, drawn with the Pencil or written live in Write, Touch and Latch. Memory locations and a big counter keep you oriented.

The Score Editor shows MIDI tracks in standard notation. In the desktop app you can also export MusicXML for Sibelius and other notation programs, or print the score.

Open the AI panel next to the app, paste an OpenAI, Google Gemini or OpenRouter key, and ask how to do something or how to fix a mix. Answers use SoundCraft’s real menus, shortcuts and plugin controls, taken from its source code.
Requests go from your browser to the provider. We never see your key or your questions, and we add no markup.
How the assistant worksThe app is the unmodified web build from SoundCraft’s GitHub release. Around it we add a few things the bare build doesn’t have.
Each new SoundCraft release is checked against its published SHA-256 checksum and deployed here. You are on v0.5.0.
One switch in the top bar starts a blank session instead of the demo, without remembering URL flags.
Mixing and how-to answers from OpenAI, Gemini or OpenRouter models, straight from your browser.
No account and no upload. Close the tab and nothing of yours is left on a server.
SoundCraft is pre-alpha software. The browser version keeps nothing: when you close or reload the tab, your changes are gone.
Yes. SoundCraft is free and open source, there is no account and no time limit. The optional AI assistant uses your own AI provider key, so any AI usage is billed by your provider, not by us.
No. A web page gets no file or audio-input access from this build: the browser version plays the built-in demo song or starts an empty session, and can’t import, record, save or bounce. The free desktop app for Windows, macOS, Linux and FreeBSD does all of that.
Not in the browser. Everything you change is lost when you close or reload the tab, so treat the browser version as a place to learn and try things. The desktop app saves sessions and autosaves with recovery.
No. SoundCraft is an independent, clean-room open-source project that follows the Pro Tools workflow. It is not made by Avid, and it cannot open Pro Tools .ptx sessions.
Browsers only start audio after you click or press a key on the page. Click once inside the app, then press Space. Check your volume first: start low.
A current Chrome, Edge, Firefox or Safari on a computer. SoundCraft draws its interface with WebGPU and falls back to WebGL2 on its own. It is built for a mouse, a keyboard and a large screen.
Not in the browser, which has only the built-in plugins. The desktop app hosts CLAP, VST3 and, on macOS, Audio Units plugins.
Free, nothing to install, and already loaded on your next visit.
