AI-Native E2E Testing​for Mobile Apps

The platform is tuned for high determinism in an E2E-testing context that still allows for self-healing. Temperature = 0.0: All LLM calls are executed with zero temperature so identical prompts produce identical completions. Model-snapshot pinning: Each test suite is locked to a specific LLM snapshot, so model upgrades never occur silently. Prompt versioning: Prompts are treated as versioned artifacts - updates trigger a new version tag, ensuring test reproducibility. Caching: Previously successful steps on the same screen and prompt input are reused to eliminate redundant calls.

We optimize performance and test runtime across both our Web Studio and SDK-based flows: Web Studio: Uses a command-first approach that works with the UI Hierarchy first and leverages AI only as fallback. This usually results in up to 70% faster execution. Screen/prompt caching further reduces test time by skipping re-execution of known good states. SDK Flow: Allows teams to wrap existing Appium/Selenium test logic with GPT Driver, enabling AI fallback only when elements fail or behavior diverges. Adds stability without requiring full migration or reauthoring.

We charge based on the number of AI steps needed for your tests. Pricing starts at $799 per month, making AI-powered test automation accessible even for small teams.

Yes, we offer a limited number of free trials. During this trial, we work with you to set up the first batch of tests so you can evaluate GPT Driver for your needs.

To get started, request a demo. Our founders will set up an onboarding call to understand your needs and show what our product can do. After the call, we can typically set up your first automated tests within a few days.

We support iOS, Android, and web platforms. Our approach is tech stack agnostic, meaning we support native languages like Swift and Kotlin, as well as frameworks like React Native, Ionic, and Flutter.

We've run over 1 million tests for our clients and built strong guardrails to ensure reliable execution. Our platform also offers tools that make it easy to write robust test prompts.

Our AI-based approach is generally slower than pure code-based scripts, but it offers benefits like reduced flakiness and lower maintenance—great for nightly tests. If speed is key (e.g., for PR tests), we support direct commands that execute instantly, using AI only when needed. We also offer parallel execution, caching, and optimized workflows for faster turnarounds.

We provide dedicated Slack channels and personalized support to all our customers. Many choose us because of our high level of assistance.

Our AI-native test execution significantly reduces flakiness in automated testing, enabling a genuine shift-left approach in mobile app development. Over the past two years, we've been developing GPT Driver, pioneering this AI-native method. Collaborating with great teams like Duolingo has helped us continuously refine the product, addressing common challenges and adapting to a wide range of setups. To our knowledge, there's nothing else quite like it available today. If you're looking to achieve more test coverage with less effort, we'd love to hear from you.
