openDAW is a next-generation web-based Digital Audio Workstation (DAW) designed to democratize music production
and to resurface the process of making music by making high-quality creation tools accessible to everyone, with
a strong focus on education and data-privacy.

Looking for Contributors
We welcome contributions that follow the existing style and conventions of the project. AI-assisted code is fine, but
every contributor must understand every line of code they submit. If you use AI tools, please document your process
in /plans. Keep pull requests small and focused. Large
PRs will not be reviewed. Split big contributions into smaller commits that add requirements gradually and maintain
operations of the app.
If you are interested in helping, here are areas where we need support:
- Offline App — e.g. wrapping openDAW with Tauri for a native desktop experience
- PWA — turning openDAW into a fully installable Progressive Web App with offline support
- Timeline Track Management — design and UX help for track layout, ordering, grouping, and interaction
We always appreciate help on open issues: https://github.com/andremichelle/openDAW/issues

Ported Plugins (Excluded in commercial license)
WebCLAP
openDAW hosts WebCLAP plugins, CLAP plugins compiled to WebAssembly, as
instruments and audio effects. Their original interfaces open in floating windows, all parameters can be automated, and
the plugins travel with the project into bundles, cloud backups and Live Rooms. Pick a plugin from the openDAW cloud or
import your own .wclap bundle.
Available in the openDAW cloud
- [Basics] Analyser, Chorus, Crunch, Frequency Shifter, Limiter, Reverb (Signalsmith Audio)
- MNO (Charlie Culbert)
- OB-Xf (Surge Synth Team)
- Pro54 (Cmajor)
- RipplerX (Tilr)
- Six Sines (BaconPaul)
- Slide (Charlie Culbert)
- Tapa (Charlie Culbert)
Repositories
Prepare, Clone, Installation, and Run
openDAW tries to avoid external libraries and frameworks. The following is a list of the external libraries we currently
use in the web studio:
Before starting, ensure you have the following installed on your system:
- Git is required for cloning the repository and managing submodules.
- mkcert is required to create a certificate for developing with
https protocol.
- Node.js version >= 23. This is necessary for running the development server and installing
dependencies.
- Sass While Sass is handled internally during the development process, you will need to
ensure you have the
binaries available in your environment if used outside the build system.
- TypeScript
- OpenSSL For generating local development certificates (), OpenSSL needs to be
installed on
your system. Most Linux/macOS systems have OpenSSL pre-installed.
- Rust (via
rustup, >= 1.82) is required to build the WASM
audio engine (@opendaw/studio-core-wasm). Without it, npm run build / npm run dev:studio fails to
resolve that package (a Vite pre-transform error), because packages/studio/core-wasm/dist never gets built.
You need:
- the
wasm32-unknown-unknown target — rustup target add wasm32-unknown-unknown
- a nightly toolchain with the
rust-src component (the device crates build with -Zbuild-std=core) —
rustup toolchain install nightly && rustup component add rust-src --toolchain nightly
- binaryen (optional) provides
wasm-opt, used to size-optimise
the WASM modules (brew install binaryen, or apt install binaryen). If it is missing, the build still
succeeds and ships unoptimised modules.
Clone
git clone https://github.com/andremichelle/opendaw.git && cd opendaw
Installation
npm run cert (only for the very first time)npm run clean (to revert to clean slate, removes all node_modules and dist folders)npm install (for the first time and after npm run clean)npm run build (for the first time and after npm run clean)npm run dev:studio | npm run dev:headless (start dev server)- Navigate to https://localhost:8080 (port is important > cors sample api)
