Launch HN: TesterArmy (YC P26) – Agents that test web and mobile apps

TesterArmy, a Y Combinator-backed startup (P26), launched an AI-powered testing platform that monitors critical user flows on web and mobile apps, alerting teams to bugs. The tool allows users to write tests in plain English, runs automatically via GitHub PR checks or scheduled monitoring, and provides screenshots and recordings for each test run.

whatever the stack

How TesterArmy catches bugs before your users do #

Explore the key features that drive our partners growth, day after day.

Create a project

Paste your staging or production URL to set up a project and test your mobile apps, web apps, and websites. No SDK, no test scripts, no infrastructure to maintain.

Write tests in plain English

Describe what to test in natural language. The AI agent navigates pages, fills forms, handles login flows with OAuth and OTP, and interacts with your UI the way a human would.

Choose how to run

Connect your GitHub App for automatic PR checks, schedule recurring runs for production monitoring, or trigger tests via webhook from any CI pipeline.

Query returns the correct filtered items and pagination controls work as expected

Get a clear report

Get screenshots, recordings, and actionable bug reports on every run, from the dashboard, via the CLI, or straight in your Pull Request.
