Three-step TesterArmy demo: Claude Code is prompted in a terminal to create a test for the API keys flow, the drafted plain-language steps run one by one in the dashboard, and a passed run lands in the run history.
Describe a flow the way you would explain it to a colleague. TesterArmy YC 26 agents follow it in a real browser or on a real device build.
The TesterArmy dialog asks "What do you want to test?" and a description is typed into it: verify checkout succeeds with a test card.
A web test in the editor: act and assert steps that open Instagram, submit an invalid login and check the error message.
Web in a browser
Web tests open your app in a real browser and click through it like a person would.
The results table: an iOS group at 22 of 25 passed and an Android group at 21 of 21, both against the production environment.
iOS from a build
Upload an iOS build from your pipeline and the agent runs the same flow on it, step by step.
Android from a build
Upload the APK your pipeline already produces and the agent runs the same flow on Android.
The Test Accounts auth-method picker: username and password, Google, GitHub, custom, magic link and SMS one-time codes.
Real test accounts
Test Accounts give the agent a real login for every run, so flows behind sign-in are covered.
Connect your repo, write the first flow
in plain language and read the result.
What stands out most is how quickly we can generate meaningful test coverage and uncover edge cases. It's given our team a better understanding of the benefits AI can bring to quality assurance, while also helping us improve efficiency and confidence in our releases.
In sixteen years of building mobile apps, TesterArmy is the first tool that actually does what I always expected AI-powered testing to do. You're onto something.
A master class in onboarding experience - my first e2e test ran in under 2 minutes and just worked. This is what I imagined agentic end-to-end testing to look like.
I have been QA for about 4 years, I used to automate with Selenium and Python. It was tiring. I am so impressed with this tool. It has sped up process of automation by 3X. I love it.
TesterArmy helped us move faster with confidence. In the last 3 months, it's caught 20 issues before they reached production, so we ship knowing problems get flagged before our users do. It fits naturally into how we ship at Copyfy.
We did not believe Testerarmy could work this well. We were wrong. Running it alongside manual QA has been a huge timesaver for our team, and setup took just a couple of minutes.
I used to manually check production after every deploy, just to be safe. With TesterArmy, I leave the office and wait for the Slack message.
Game-changer for our site rollout - caught several regressions in the first couple of weeks. Automatic auth with test accounts was the blocker that killed our earlier QA attempts, and now we monitor our logged-in dashboard continuously without thinking about it.
TesterArmy is a core part of my software factory. Exploration tests for every PR is a killer feature.
Finally something that allows me to confidently ship my heavily prompt engineered prototypes to live customers.

The same tests run on every pull request, from your CI job, on a schedule against Production, or by hand. Every run lands in one Results table.
Pull request, CI, scheduled and manual runs share one table with status, platform, environment and trigger.
Configure Trigger runs a test group against Production every hour, day or week, or from a webhook.
A check appears on the pull request and reports the result before anyone merges.
One command in your workflow runs the tests after deploy and writes the result to a file.
A Slack message names the failed test, the step and what the agent saw, with a link to the run.
Claude Code, Codex and Cursor connect over one MCP endpoint. Your agent creates the test, runs it and reads the report without leaving the session.
tester.army
A Claude session where the agent creates a TesterArmy test over MCP, queues the run on TesterArmy cloud against the Staging environment and reads back a report of three passed steps with no issues.
Web, iOS and Android builds, React Native and Expo, WordPress and storefronts. The same plain-language tests, run from CI or from your coding agent.
