What It Is
Buoy is like having Chrome DevTools built directly into your mobile app. Instead of connecting to a remote debugger, you get a floating menu inside your React Native or Expo app that lets you see and change things on the fly, like network calls, local storage, or even React Query caches.
This kills the slow feedback loop of traditional mobile debugging. Developers can quickly diagnose issues, test different states, or even impersonate users without rebuilding or redeploying. It also offers an 'MCP server' for AI agents to interact with the app, opening doors for automated testing and interaction.
License Verdict
Proprietary Software — No Commercial Use Without License — Commercial Use Restricted • Requires Paid License for Advanced Features
Buoy is proprietary software. This means you cannot use, modify, or distribute it commercially without obtaining a specific license from Buoy LLC. While basic usage might be possible, advanced features and production use will require a paid account, as indicated by their pricing page and terms of service. You cannot fork this project and build your own competing product.
How to Use It
Buoy provides an in-app developer toolkit for React Native and Expo applications. To get started, you install the core package and specific tools like 'network' via npm. You then need to log in to your Buoy account and integrate the floating menu into your app's code, typically in a development build.
Prerequisites:
- React Native
- Expo
- npm or yarn
- Buoy Account (Free or Pro)
Estimated setup time: 15 minutes.

Custom DevTool Kits for Agencies (micro-saas)
Offer specialized Buoy configurations and custom tool development as a service for mobile development agencies. Many agencies struggle with consistent debugging environments across diverse client projects, and this service would provide tailored Buoy setups. You'd package specific tools and create custom integrations for their workflow, leveraging Buoy's paid tiers.
Effort: 1 Week Build Time · Target: Mobile Dev Agencies · Pricing: $199/mo per client project
AI-Powered Mobile App QA & Testing Platform (saas)
Build a platform that leverages Buoy's MCP server and Sim Farm to allow AI agents to interact with and test mobile apps automatically. Users define test scenarios, and the AI agents execute them across various simulated devices, reporting bugs and performance issues. This would significantly reduce manual QA effort and speed up release cycles.
Effort: 3 Months Build Time · Target: Mobile Dev Teams / QA Departments · Pricing: $499 - $1,999/mo based on usage
Internal Mobile App Debugging & Support Portal (enterprise)
For large enterprises with internal-facing mobile apps (e.g., field service, retail staff), create a custom portal that integrates Buoy's capabilities. Support staff could remotely connect to a user's app (with permission) via Buoy Desktop/MCP to diagnose issues, change settings, or collect logs without requiring the user to send screenshots or rebuild. This streamlines internal support for proprietary apps.
Effort: 6 Months Build Time · Target: Large Enterprises (IT/Support) · Pricing: $10k - $50k/year per organization
Sai Pavan Gopularam's Take
Buoy solves a real pain point in mobile development: slow debugging. The 'in-app' approach is smart, and the AI agent integration (MCP) is where the real leverage is. I'd estimate a well-executed SaaS for AI-driven mobile QA using this could hit $100k ARR within 18 months, assuming strong marketing to dev teams.
Watch Out For
- Proprietary License: Buoy is proprietary software, meaning you cannot fork it or build a competing product. Commercial use of its features, especially advanced ones like MCP and Sim Farm, requires a paid license from Buoy LLC.
- Requires Account: To use Buoy, you need a free or Pro Buoy account. Some advanced features are gated behind the Pro tier, which implies ongoing subscription costs for advanced functionality.
- Development Builds Only (by default): Buoy is designed for development builds. Enabling it in a shipped production app requires a Pro account and careful implementation of your own access checks to prevent unauthorized access to debugging tools.
