KeyEcho

KeyEcho

KeyEcho is a tiny open-source desktop app that plays pleasant keyboard sounds while you type. It is built with Tauri, Rust, and Solid, and is designed to stay local, fast, and easy to audit.

Why

• Local keyboard event handling for low-latency sound playback.
• Cross-platform builds for Windows, macOS, and Linux.
• Small native desktop footprint instead of a bundled browser runtime.
• No account, cloud sync, or typing-content analytics.
• Custom sound packs for people who want to tune the typing feel.

Sound Packs

KeyEcho itself stays free and open source. Paid premium sound packs are planned as optional content that funds recording, tuning, and maintenance.

The current founding bundle is a one-time $9.99 early-supporter offer:

• Includes the first batch of studio-recorded premium packs.
• Includes any extra premium packs released during the founding period.
• Gives founder vote priority for the next pack queue.
• Is not a subscription.
• Is not required to keep using KeyEcho.
• Is not a lifetime pass for every future sound pack.

You can vote for the next packs or back the founding bundle on keyecho.app.

Install

Download the latest build from the GitHub Releases page.

Supported targets:

• Windows x64 / ARM64
• macOS Intel / Apple Silicon
• Linux x64 / ARM64

KeyEcho needs the operating system permissions required for global keyboard event listening. It maps key events to local sound playback; it does not upload typed content.
