Native Rust vs Chromium Wrappers

Why Engineers Choose Rust Over Electron

Clipboard utilities should sit silently in the background, consuming practically zero resources until summoned.

RAM Consumption
Nesto (Rust Core)~28 MB
Typical Electron App320+ MB

91% memory savings. Zero bloated Chromium renderer processes.

Cold Launch Time
Nesto (Rust Core)< 85 ms
Typical Electron App1,450 ms

17x faster cold launch on boot. Instant background thread startup.

App Installer Size
Nesto (Rust Core)~14 MB
Typical Electron App165 MB

12x smaller. Uses system-provided webviews instead of bundling V8.

Ergonomic Keyboard Engine

Built for 100% Keyboard Flow

Every action can be triggered in a single keystroke. No reaching for the mouse, no awkward window management.

Under The Hood

Engineered with Rust, Tauri v2 & SQLite

Modular architecture split between high-performance system hooks and an ultra-lean interface.

Rust Core Architecture

  • arboard: Cross-platform clipboard listener running on a dedicated worker thread with zero CPU wakeups.
  • rusqlite WAL: Embedded relational storage with WAL (Write-Ahead Logging) mode for ultra-fast full-text substring searching.
  • enigo & macOS Accessibility: Low-level keyboard event injection that automatically simulates Ctrl+V / Cmd+V into previous active window.
  • tauri-plugin-autostart: Safe login item registration that runs directly on boot without antivirus false positives.

Local SQLite Data Paths

You own 100% of your data. The SQLite database is stored locally inside your OS profile directory with zero cloud synchronization.

Frequently Asked Questions

Nesto listens directly to OS clipboard headers (org.nspasteboard.ConcealedType on macOS and Clipboard Viewer Ignore on Windows). When password managers like 1Password, Bitwarden, or KeePass copy a credential, Nesto ignores it automatically. You also have a single-click Pause Recording button in the titlebar.
