Use Momentic to test web, iOS, and Android apps. Mo explores a running app from a brief and reports findings with evidence. For repeatable regression checks, keep YAML tests in your repository and run them locally or in CI.

​
Test a running app with Mo

Give Mo a URL or an uploaded mobile build, the behavior to check, and any required test accounts. You can test a preview deployment, a release candidate, or a local web app through a tunnel without writing test files. The session report records test cases, verdicts, coverage gaps, and findings with reproduction steps. A separate agent attempts to reproduce functional bugs; static findings, such as a typo, use a screenshot.

Run your first Mo session

Select a target, write a brief, and review the report.

Use Mo from a coding agent

Start sessions with the qa CLI, answer questions, and export findings.
See when to use Mo for how sessions fit alongside coding agents and repository tests.

​
Run your first test

Momentic tests mix preset steps, AI actions, and modules in YAML files you can review in Git. Use them to check the same behavior on each pull request or release. Run the wizard and choose web, iOS, or Android. It signs you in through the browser, installs the matching CLI, writes momentic.config.yaml and a sample test, and runs the sample. It also offers to set up your coding agent:
After the sample passes, use the web, iOS, or Android quickstart to run one test against your own app and check its result. To use a coding agent instead, paste the web setup prompt into Claude Code, Cursor, Codex, Copilot, or any other agent. The agent runs the wizard with an API key and writes your first test. The mobile quickstarts include setup prompts for iOS and Android.

For AI agents

  • llms.txt: an index of every page. llms-full.txt: every page in one file. Append .md to any page URL for clean Markdown.
  • skill.md: the capability summary for agents.
  • npx momentic skills --yes: install the Momentic skills into your repository (npx momentic-mobile skills --yes for mobile).
  • qa skills --yes: install the Mo skill after installing the qa CLI. Coding agents use it to start, follow, and recheck Mo sessions.
  • MCP server: a local stdio server that gives a coding agent a live browser or device plus tools to author, run, and triage tests.

​
Pick your platform

Web

Chromium-based browsers, locally or in CI

iOS

Local and remote simulators without real devices

Android

Local and remote emulators for APK-based apps
React Native, Expo, and Flutter apps use the iOS and Android quickstarts. Momentic tests the native build, and each quickstart shows the build command for your framework.
