Describe a task in plain English; Deltix runs it on a simulator and tells you if a real user could complete it. Start free, watch a real run, Open beta for iOS today – no credit card needed.

Privacy by default: your source and build stay on your Mac. The Mac Agent runs locally against your simulator and never accesses your source, build, or signing identities. While a run is in progress the agent acts on what it sees on screen, like any user would. Screenshots and the run record sit in your account so you can review and replay; delete anytime, or bring your own model key to route inference traffic off our bill.

Ad‑hoc: try once to see if a user can complete a flow. Playbook: save a successful run and replay it deterministically on every build from the dashboard. Experiment: run the same task against two builds side‑by‑side to see which design wins before A/B testing. The agent reports each step, what it saw, and what changed. Future work includes physical devices, Android emulator, CLI for CI, and hybrid‑app support.

To get started, install the small native Mac Agent, sign in with your account, connect any iOS Simulator already running on your Mac, write a task like “sign up and send your first message,” and watch the agent work. Sign up free, verify your email, and you’re in – no credit card, no invite.
