Deltix

Test your mobile app like a real user. Describe a task in plain English. Deltix runs it on a simulator and tells you if a real user could complete it.

Your source and your build stay on your Mac. The agent runs locally against your simulator. We never access your source, your build, or your signing identities.

Four steps to your first run.

1. Sign up: Free. No credit card. No invite needed. Verify your email and you’re in.
2. Install the Mac Agent: A small native app. Sign in with the account you just created. That’s the only one-time setup.
3. Connect a simulator: Pick any iOS Simulator already running on your Mac. The Agent attaches to it and stays out of your way.
4. Run your first task: Write a task in plain English, like "sign up and send your first message." The agent tries it. You watch it work.

One primitive, three modes.

Everything in Deltix is built on a single thing: an AI agent attempting a user task. The three modes are the three ways you run it.

Task. Try once.

“Can my user actually do this?” Ad-hoc. You’re building a new flow and you want to know if it works for a real user, without scheduling a research session. Write the task, watch the agent try, read the screenshot of where it got stuck.

Playbook. Save and replay.

“Did we break it?” Take any successful run and save it as a Playbook. Replay it deterministically on every build, from the dashboard. Pass or fail in seconds.

Experiment. Compare two builds.

“Which design wins?” Run the same task against two builds of your app, side by side. See which one your users can complete and which one breaks, before the design debate goes to A/B testing in production.

From discovery to regression.

Most testing tools force a choice. Deltix does both.

1. Explore: Describe a task in plain English. Deltix navigates your app like a first-time user, discovering, hesitating, succeeding, or getting stuck. Every step is captured.
2. Save: When a run completes the flow you wanted, save it. One click turns the successful path into a deterministic playbook. Same interactions, same targets, every time.
3. Replay: Replay the playbook from the dashboard against any new build. Same interactions, same checks. Pass or fail in seconds, with no flaky XCUITest assertions to maintain.
