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:

1. Offline App — e.g. wrapping openDAW with Tauri for a native desktop experience
2. PWA — turning openDAW into a fully installable Progressive Web App with offline support
3. 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

• Fade-in and out on audio-regions
• Signature automation track
• Tempo automation track
• Fine-tune recording including loops (takes)

2026/Q2

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:

• jszip (for openDAW project bundle file)
• markdown-it + markdown-it-table ( for help pages)
• d3-force (for graph debugging)
• soundfont2 (for soundfont loading)
• zod (schema validation)
• ffmpeg (decoding/encoding)

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)
