Introduction

MobileBoost, whose product was known as GPT Driver, is an AI test automation service for mobile app QA, backed by Y Combinator according to its site. The MobileBoost Test Agent consumes pull-request content, generates or extracts test cases, runs them on simulators or real devices in parallel, and posts results back to CI status checks.

The site also describes agent skills so coding agents can author tests that match your standards, a REST API for programmatic test management, a visual editor, and natural-language test creation.

Features

  1. PR-triggered agent: Detects PR changes, generates tests, runs them and posts pass/fail with artifacts to CI.
  2. Agent skills: Skills and guidelines help coding agents write tests to your standards; an example outputs XCUITest.
  3. API-first test management: A REST API built for programmatic creation and maintenance.
  4. Automated maintenance: The agent updates tests when the app changes.
  5. Visual editor and plain English: Non-engineers can review and adjust tests.
  6. Device features: Offline mode and App Clips on iOS simulators, audio I/O, camera injection, network capture and mocking.
  7. Scale and extras: 100+ parallel executions, performance regression checks and accessibility (WCAG) flags.

Pros

  1. Mobile depth: Camera injection, audio and App Clips address hard mobile cases.
  2. CI-native: Results arrive as status checks on PRs.
  3. Real and virtual devices: One API for both.
  4. Built for coding agents: Skills and an API suit agentic workflows.
  5. Named users: Testimonials from engineers at Lyft, Noom, Compass and Duolingo; vendor-supplied.

Cons

  1. No public pricing: The site does not list prices; see site.
  2. Hosted infrastructure: Execution runs on MobileBoost’s device setup.
  3. AI maintenance needs review: Automatic test updates can hide intended or unintended changes.
  4. Mobile only: Not a web or API testing tool.
  5. Rebranding: Naming moved from GPT Driver to MobileBoost Test Agent, so older material may differ.

The documented loop: a pull request opens, the Test Agent detects changes, generates or extracts test cases, runs them on simulators or devices, and posts results to CI. Teams can also author tests in plain English or the visual editor, or create them through the REST API. Contact MobileBoost to set up a workspace.

Pricing

MobileBoost does not publish prices on its homepage. See site or contact the company.

  1. Mobile teams shipping nightly builds that want PR-level end-to-end checks.
  2. Apps with camera, audio or offline flows that are hard to automate.
  3. Teams with coding agents writing mobile features.
  4. Not a fit for web-only products.

Conclusion

MobileBoost is a mobile-focused AI test agent with unusual device capabilities and CI-native reporting.

Pricing is by request and maintenance is automated, so plan a pilot that includes review of the agent’s test updates.
