BuilderStudio

BuilderStudio is a free, native multi-OS agentic coding IDE that brings local AI-powered development, multimodal asset generation, and a terminal-first CLI into a single creative suite for macOS, iOS, and command-line workflows.

What is BuilderStudio?

BuilderStudio is a native desktop IDE for macOS (with an iOS companion app and a bs CLI for macOS/Linux) that lets you build app projects locally using AI agents. It takes natural language prompts or code inputs and produces working applications through coordinated agent swarms, containerized execution, and control-plane deployment handoff. Built by WunderCorp, it integrates OpenRouter for 300+ AI models, MCP for tool connectivity, and reusable Skills for workflow automation.

Key Features

• Agentic Swarms and Skills — Use the desktop IDE or bs CLI to run parallel specialized AI agents with project permissions, command execution, and reusable Skills that add capabilities like accessibility checks or release workflows.
• Containerized Hermes Execution — Hermes Agent creates a dedicated project folder mounted as /workspace inside a secure local container, auto-starting the app preview when the agent finishes.
• 300+ AI Models via OpenRouter — Choose from a wide range of models for speed, quality, or cost; configure via bs init with your OpenRouter key.
• Built-in MCP Support — Connect your AI coding agent to tools, services, and project context through Model Context Protocol servers.
• Cross-Platform Clients — Download BuilderStudio for macOS (97 MB), iOS via App Store, or install the bs CLI globally via npm (@wundercorp/bs) for terminal-first development.
• Deploy to Any Hyperscaler — Build locally with agent swarms, then hand the generated source package to the control plane for deployment, auth, integrations, and app management.
• Source Editing and App Previews — Code in a native editor, preview generated apps inside isolated machines, and package source for handoff.

Who is it for?

• Solo developers and startups — Build app projects from idea to working product using AI agents without setting up cloud infrastructure.
• Terminal-first engineers — Run the bs CLI from any terminal or external IDE (Cursor, Windsurf, VS Code) for headless agent workflows.
• Mobile creators — Use BuilderStudio Mobile on iPhone/iPad to initiate or monitor development sessions on the go.

What can you do with BuilderStudio?

• Build a feature from a prompt: Run bs gain "build the feature" to generate a working app in your current project folder, with auto-preview and repair loops.
• Prototype with reusable components: Use the Hermes agent to pull from a 6000+ UI component library (awesome-components) and assemble apps quickly.
• Combine local and cloud models: Use openmodel (wundercorp/openmodel) to switch between on-device and cloud models while tracking token usage.

How does BuilderStudio work?

1. Install the bs CLI via npm install -g @wundercorp/bs or download the macOS app.
2. Run bs init to configure your OpenRouter key and default model route.
3. Use bs gain "build the feature" (or the desktop IDE) to launch an agentic swarm inside a Hermes container.
4. The agent writes files to a fresh project folder, BuilderStudio detects the app shape, and auto-starts a preview.
5. When ready, hand the source package to the control plane for deployment.
