Rule-based routing
Route by domain, rule set, or region, with policy groups for automatic failover and manual picks.
Coming soon to the App Store
The proxy toolkit for iPhone.
Grbit is a rule-based proxy client and network utility. Bring your own servers. Everything runs on your device.
A tool, not a service.
Grbit does not provide, sell, or bundle any servers. You connect to infrastructure you already own or subscribe to, and Grbit gives you precise control over how your traffic gets there.
Your servers
Works with infrastructure you provide, whether self-hosted or from providers you already trust.
Your rules
Domain, region, and protocol rules decide which connections go where. You write them, you own them.
Your device
All processing happens locally through Apple's Network Extension framework. Nothing passes through us.
What's inside.
A complete client for people who want to see and shape their network traffic.
Native to iOS
Built with SwiftUI. Full light and dark appearance, Dynamic Type, no web views.
Modern protocols
Shadowsocks, VLESS, Trojan, and more, powered by Comet, our proxy engine written in Rust.
Subscription import
Import the subscriptions you already have. Common list and Clash formats are parsed natively.
Live monitoring
Watch throughput and active connections in real time, straight from the tunnel.
Latency tests
Test every member of a policy group and pick the fastest path with one tap.
A full diagnostics bench
DNS tools, traffic records, packet capture, HTTP rewrite, and scripting, all processed on your device.
Private by design.
Grbit has no backend. There is nothing for us to collect, so we collect nothing.
- No accounts, no analytics. The app has no sign-in, no tracking SDKs, and no advertising.
- Configuration stays local. Servers, rules, and credentials live on your device, with secrets in the iOS Keychain.
- Traffic goes where you point it. Connections run from your device to your servers. We never sit in the middle.
