PLUGIN ECOSYSTEM

Plugins load as JSON.
No page refresh.

Cloud subscribers get a one-click plugin manager. The app fetches your installed plugin list from Postgres on session start and lazy-loads only the scripts you need — nothing else runs.

How plugin install works
Cloud subscribers get one-click install. Free users can still install by pasting a script URL. No coding either way.

Sign in and open Plugin Manager

Browse the registry and click Install

WavrPro is Ready to Go!
☁ Cloud only. Free users can install plugins by uploading a .js file or pasting a CDN URL directly in the DAW — the technical capability is the same, the UX is just more streamlined for Cloud subscribers.
HOW IT WORKS

Your audio never
leaves your browser.

The cloud stores session metadata and .wavrproj blobs. All audio processing — recording, mixing, export — runs client-side via the Web Audio API. We can't hear your music even if we wanted to.

🌐
Web Audio API
All synthesis, mixing, EQ, and export happens in your browser. OfflineAudioContext for bouncing. MediaRecorder for mic input. No audio server.
💾
We store .wavrproj files
Sessions are JSON blobs containing pattern data and metadata. Audio data is embedded as compressed PCM. Stored in Supabase Storage — encrypted at rest.
🔓
Open source, always
The entire stack is on GitHub under AGPL 3.0. The DAW, plugins, SDK, and cloud backend. If we ever shut down, you have everything. No lock-in.
Start making music.
Right now.

Open the DAW in one click. No account. No install. No credit card. Cloud sync when you're ready.
