Key point

Deltix, an AI agent-based tool that performs mobile app testing using natural language, has been released.

Details

Deltix is an AI agent-based testing tool that executes tasks described by users in natural language on mobile simulators, mimicking real user behavior.

It adopts an approach where a local agent running on Mac recognizes the screen and acts, without accessing the user's source code or build data.

Core features are divided into three modes:

  • Task: One-off tests to verify that new app flows work correctly.
  • Playbook: Regression tests that save successful runs and reproduce them on every build.
  • Experiment: Experiments that compare two builds to verify differences in design or functionality.

An open beta is currently underway targeting iOS simulators, and users can connect and use their own model keys. Android support and CI (such as GitHub Actions) integration are planned for the future.
