SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Capabilities provide granular control over which APIs and commands each window or webview can access, enabling tighter security boundaries in Tauri apps.

Core Features & Use Cases

  • Define per-window permissions with window labels to minimize blast radius
  • Place capability definitions in src-tauri/capabilities/ and reference them from tauri.conf.json
  • Support platform-specific targeting and optional remote access for centralized policy management

Quick Start

Create a capability file under src-tauri/capabilities for the main window and add its identifier to tauri.conf.json to enforce least-privilege access.

How do I restrict Tauri API permissions to specific windows?▼

You restrict Tauri API permissions per window by creating capability files under src-tauri/capabilities, labeling windows, and referencing them in tauri.conf.json to enforce least-privilege access.

What are Tauri capabilities and when do I need them?▼

Tauri capabilities are configurations that provide granular control over which APIs and commands each window or webview can access, enabling tighter security boundaries in multi-window desktop applications to minimize blast radius.

How do I set up per-window capabilities in a multi-window Tauri app?▼

You set up per-window capabilities by creating a capability file in src-tauri/capabilities, defining window labels and permissions, applying platform-specific targeting, and adding the identifier to tauri.conf.json.

Can I target specific platforms when defining Tauri window permissions?▼

Yes, Tauri capabilities support platform-specific targeting within the capability definition structure, allowing you to restrict window permissions to certain operating systems and optionally manage remote access for centralized policy.

Why are my Tauri frontend windows over-privileged?▼

Tauri frontend windows become over-privileged when capabilities are not configured per window, which is solved by placing structured capability definitions in src-tauri/capabilities and wiring them into tauri.conf.json.

Does Tauri support remote access configuration for window capabilities?▼

Yes, Tauri capabilities support optional remote access configuration for centralized policy management, allowing granular control over which APIs and commands each window or webview can access.
