Pastily Security Review: Resolving Cross-Platform Desktop Sandbox Issues
A review of clipboard isolation, application sandbox scopes, and how we ensure secure IPC boundaries between the Rust backend and React frontend.
Security is the foundation of Pastily. Operating local-first requires isolating clipboard history from other applications, maintaining secure boundaries on your system.
Direct Answer: Pastily secures its IPC channels by validating all React frontend queries against a sandboxed Rust backend using Tauri's strict permissions, blocking unauthorized database access.
By using Tauri, we avoid the security risks of standard web wrappers. The frontend only communicates with the backend through specific, safe API commands. This ensures that your clipboard database remains secure and isolated.
Sandboxed SQLite Security
Your clipboard history is saved in a local, sandboxed directory, preventing unauthorized apps from reading your data. This local isolation gives you full security and peace of mind.
