Test your mobile app like a real user with AI agents
Deltix is an AI-powered mobile app testing tool that runs on your Mac and lets you write tasks in plain English. An AI agent executes those tasks on an iOS Simulator and tells you whether a real user could complete them, capturing screenshots and step-by-step progress. It’s designed for developers and product teams who want to test real user flows without writing fragile UI test code — you can explore new features, save successful runs as deterministic playbooks, and replay them against future builds to catch regressions. The tool prioritizes privacy by keeping your source, build, and signing identities on your Mac, and it’s currently in open beta with no credit card required.
Describe a user task in natural language (e.g., "sign up and send your first message") and the AI agent tries to complete it on your simulator.
The agent runs against an iOS Simulator already running on your Mac, keeping your source, build, and signing identities local — they are never accessed or transmitted.
Task (try once to see if a flow works), Playbook (save a successful run and replay it deterministically), and Experiment (run the same task against two builds side-by-side to compare outcomes).
One click turns a completed user flow into a deterministic playbook that replays the same interactions and targets on every new build.
Playbooks can be replayed from the dashboard against any new build, giving pass/fail results in seconds without maintaining flaky XCUITest assertions.
Each run shows the agent's actions, what it saw on screen, and what changed at every step, making it easy to understand where a flow breaks.
Screenshots and run records are stored in your account (deletable anytime), and you can bring your own model key to route inference traffic off Deltix's infrastructure.
No. Your source, your build, and your signing identities stay on your Mac. The agent runs locally against your simulator, and Deltix never accesses these files.
Sign up for free (no credit card, no invite), install the Mac Agent, connect an iOS Simulator that's already running on your Mac, and write your first task in plain English.
Yes, you can bring your own model key to route inference traffic off Deltix's infrastructure, which may be useful for privacy or cost management.
Currently, Deltix supports iOS Simulator on Mac in open beta. Physical devices (real iPhone) and Android emulators are listed as in progress or next.
Screenshots and the run record sit in your account so you can review and replay them. You can delete them anytime.
