Enterprise-grade security for developers who take privacy seriously
All data transmitted between your device and our servers is encrypted using TLS 1.3. Your code never travels unprotected.
We use GitHub's secure OAuth flow. We never see or store your GitHub password—only authorized access tokens that you can revoke anytime.
Your code is processed for AI generation but not permanently stored on our servers. Your projects live in your GitHub repositories—where they belong.
Everything you create is 100% yours. We claim no intellectual property rights over the applications you build with Kestrel.
Everything you need to know about Kestrel
Kestrel is a mobile IDE (Integrated Development Environment) for iOS that lets you build, preview, and deploy web applications directly from your iPhone. It combines an AI-powered code generation agent with a full development workflow including GitHub integration, live preview, and cloud builds.
While some familiarity with web development concepts helps, our AI agent can generate complete applications from natural language descriptions. Beginners can start with simple prompts and learn as they go, while experienced developers can use Kestrel to accelerate their workflow.
Kestrel generates Vite + TypeScript + React applications. The output is Capacitor-ready, meaning you can compile your web app into native iOS and Android applications. This gives you the best of both worlds: rapid web development with native app distribution.
You sign in with GitHub OAuth, which gives Kestrel secure access to your repositories. You can browse repos, select branches, push changes, and trigger GitHub Actions workflows—all from within the app. Your code stays in your own GitHub account.
Cloud builds use GitHub Actions to compile your project on GitHub's servers. When you push code, Kestrel can trigger a build workflow, wait for it to complete, and download the compiled artifacts directly to your device for preview. This offloads heavy compilation work to the cloud.
Yes! You can cancel your Kestrel Pro subscription at any time. You'll retain access to all paid features until the end of your current billing period. No commitments, no hassle.
Absolutely. All communication is encrypted with TLS 1.3. Your code is processed for AI generation but not permanently stored on our servers. You retain full ownership and intellectual property rights to everything you create. See our Privacy Policy for details.
Kestrel requires an internet connection for core features like AI code generation, GitHub sync, and cloud builds. However, you can view and edit previously downloaded code locally, then sync when you're back online.
The in-app preview shows your web app running in a WebView inside Kestrel—great for development and testing. For production deployment, you can use Capacitor to wrap your app as a native iOS or Android application, then submit it to the App Store or Google Play.
Kestrel Pro subscribers get priority support. You can reach us at contact@kestrel.bot for any questions, issues, or feedback. We typically respond within 24 hours.
