What Maestro does

Maestro, operated by California-incorporated mobile.dev, is an open-source end-to-end UI testing framework for mobile and web applications. The platform is built around human-readable YAML test scripts that support iOS, Android, React Native, Flutter, and web targets, and is distributed through a product-led growth motion with a free local CLI, a desktop IDE (Maestro Studio), and a hosted parallel execution cloud. The repository (mobile-dev-inc/maestro) carries 15k+ GitHub stars and the framework is publicly used by Microsoft, Meta, Amazon, Uber, DoorDash, xAI, Block, Atlassian, Stripe, Brex, Flipkart, Eneco, Wahed, Doccla, Komoot, and many other enterprise and consumer brands, with documented case-study outcomes such as Eneco reducing regression cycles from 16+ hours to under 1 hour and Wahed cutting test creation time by 95% versus Appium.

The commercial model is freemium-to-SaaS: the local tier is free and open source; the Maestro Cloud tier is priced at $250 per concurrent device per month with self-serve signup and a 7-day trial; and Enterprise contracts add SSO, dedicated support, fully-managed test cases, and custom security review. The product surface has expanded materially in 2025-2026 to include Maestro MCP (a Model Context Protocol server exposing device control to AI coding agents such as Claude Code, Cursor, Codex, GitHub Copilot, Gemini, Windsurf, JetBrains AI Assistant, and Grok Build), Maestro Viewer (live device embedding inside agent workflows), MaestroGPT (an in-CLI AI assistant), visual testing, self-healing tests, and new device coverage including iOS 26 and Android 15/16. The company has only disclosed a single $3M seed round from Cowboy Ventures in July 2021 and achieved SOC 2 Type 2 certification in December 2022, suggesting capital-efficient scaling to date.
