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. Optional Crafted Packs are one-time purchases. They are not a subscription, and they are not required to use the app.

Crafted Packs are $3.99 each. All Sounds Forever is $9.99 once and includes every current and future official Crafted Pack. Browse and try them at keyecho.app/packs (opens in a new tab). Free packs download into the app; paid packs unlock with a license key.

Want to create your own? See the [custom sounds guide](docs/guides/custom-sounds.md) for recording, processing, and adding your own sound packs to KeyEcho.
