SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Managing security in Tauri apps requires precise, per-window permission configurations to prevent overprivilege and reduce attack surfaces. This skill guides developers through structuring capability files, mapping windows to granular permissions, and applying platform-specific rules to harden desktop apps.

Core Features & Use Cases

Granular security mapping: define which APIs each window can access using capability files under src-tauri/capabilities.
Per-window boundaries: assign permissions to individual windows and support wildcard labels for scalable apps.
Platform-aware configuration: tailor capabilities to Linux, macOS, and Windows with optional remote or inline schemas.
Use Case: secure a multi-window application by isolating file-system access to the settings window while the main window has broader but controlled rights.

Quick Start

Configure a capability for your main window by creating src-tauri/capabilities/main.json and referencing it from tauri.conf.json, ensuring least-privilege defaults.

FAQPage Schema

How do I configure per-window permissions in a Tauri application?▼

To set up Tauri capabilities, create a JSON or TOML file under src-tauri/capabilities, define the target windows and their specific API permissions, then reference this file from tauri.conf.json to apply the security configuration.

Can I assign different Tauri capabilities to specific operating systems?▼

Yes, Tauri capability configurations are platform-aware, allowing you to tailor permissions specifically for Linux, macOS, and Windows. This ensures window permissions are precisely mapped and restricted per target operating system.

What is the best way to secure a multi-window Tauri desktop app?▼

The best way to secure a multi-window Tauri app is by isolating permissions through capability files. This prevents overprivilege by ensuring only designated windows can access specific APIs like the file system.

How do wildcard labels work for Tauri window capabilities?▼

Wildcard labels in Tauri window capabilities allow scalable permission assignment across multiple matching windows. This maps broad permission sets to grouped windows, simplifying configuration while maintaining strict API access boundaries.

Why does my Tauri window have access to APIs it should not?▼

Tauri windows gain unintended API access when capability files grant overprivileged permissions. Refine capabilities under src-tauri/capabilities to tightly control window permissions and reduce the application's attack surface.
