Open source client

The same client our CI runs

The testerarmy package talks to the TesterArmy API from a terminal, a CI job or a coding agent. About ten thousand downloads a month.

Built for agents

Agent skills and safe defaults

One command installs the skill, and output is JSON on request. Scout blocks writes by default; unbox-ai never opens a server by accident.

Maintained by core contributors

Built by React Native contributors

Co-founder Oskar Kwasniewski has 113 commits in React Native core and maintains MiniSim, the simulator launcher for macOS.

[02] Get started

One command each

Every tool runs from npx and ships an agent skill. e2e, Scout and unbox-ai work without a TesterArmy account; the CLI needs a TesterArmy API key.

e2e

Describe a goal in plain language and an agent drives your web or mobile app to reach it, then check the result with locators and assertions. Passing agent steps replay with no model calls.

npx e2e@latest init

GitHub Docs

TesterArmy CLI

Runs your saved TesterArmy tests from a terminal, a CI job or a coding agent, executes them in TesterArmy cloud, and prints a pass or fail your agent can parse with --json.

npx testerarmy agent init

GitHub Docs

Scout

Parses your OpenAPI spec, runs instrumented requests inside a host allowlist, and records findings and coverage.
