ALPHA / VST3 FIRST RUST / VST3 / WEBVIEW APACHE-2.0 ↗

Vesty · The Rust plugin framework

Native sound.
Your interface.

Author VST3 effects and instruments in Rust, keep DSP inside an explicit realtime boundary, and build the editor with a directly embedded system WebView.

01 / Concepts

Native DSP and Web UI on opposite sides of the realtime boundary.

The VST3 adapter borrows host audio and events into Rust process contexts. The editor talks to the controller through typed JSBridge, never to the audio kernel.

AUDIO THREAD / BORROWED BUFFERS

  1. 01HostAutomation, events, transport
  2. 02VST3 adapterABI, buses, state, ordering
  3. 03Audio kernelBorrowed buffers, bounded DSP

CONTROL & EDITOR / OUTSIDE PROCESS()

Web editor↔ JSBridge ↔Controller

Host-mediated parameter edits; bounded queues carry meters and diagnostics out of the audio thread.

02 / Guides

Complete the VST3 workflow

Follow Vesty’s workflow from stable parameters and sample-accurate processing to a packaged plugin, validator reports, and DAW evidence.
01
Complete plugin tutorialScaffold an effect, implement automation-safe DSP, test it, and package the VST3 bundle.
02
Make it respond to MIDIHandle notes, automation, dense event batches, and zero-frame contexts at the right sample.
03
Host-authoritative Web UIInitialize from ready.paramValues and send edit gestures through vesty-plugin-ui.
04
Package and validateCheck bundle metadata, exports, and manifests, then collect validator reports and evidence from real DAWs.

03 / THE CONTRACT

No allocation. No locks. No WebView in process().

Vesty resolves parameter handles before processing, borrows host buffers for one block, and moves UI communication outside the audio callback.
