Your messages stay yours.
Built for privacy from the ground up. No cloud, no relay server, no Firebase. Everything runs on your Mac.
Read-only by design
Gabby opens your message database in read-only mode. It cannot modify, delete, or alter any messages.

The WebSocket server binds exclusively to 127.0.0.1. No remote network access, no open ports.
Your API key, your AI
Bring your own OpenAI key. AI requests go directly from your Mac to OpenAI. Never through Gabby servers.
No telemetry
Zero tracking, zero analytics on message content. Your conversations are never logged or transmitted.
Parameterized queries
All database access uses parameterized SQL. Injection attacks are impossible by design.
