Why RunWhale

A focused development loop,
right on your phone.

Not a remote desktop. Not a cloud IDE. RunWhale puts a focused, controlled development environment on the device itself.

An AI coding agent that works in your project

Ask it to inspect, edit, test, and repair your code. RunWhale works inside the project, not beside it.

Inspect · Edit · Test

Web and Native Preview

Run compatible projects in Web Preview, or preview Expo projects natively on iOS and Android—without triggering cloud builds or native builds for the user project.

Web · iOS · Android

On-device workspace

Core development runs on your phone. Model inference, explicit network Git operations, and uncached dependency downloads use the network.

Local tools · Connected models
From repository to result

Open a project. Ask the agent. Preview the result.

Less context switching, more forward motion. Every step stays connected inside one durable project session.

01

Start a project

Create a Web or Expo project, or import a compatible Git repository.

02

Hand it to the agent

Let it inspect, modify, and verify the code. Review write actions when you want control.

03

Preview on device

Start Web or Native Preview through embedded Metro and see the result immediately.

Local-first architecture

The development workspace stays on your device.

Projects, developer tools, and Preview run locally. Model inference sends your prompt and the project or session context needed to answer it to the provider you configure. Explicit Git operations and uncached dependency downloads also use the network.

API keys stay in system secure storage and never enter projects, environment variables, sessions, logs, or Preview bundles. How RunWhale handles project context.
