You describe a test in plain English. The agent executes it on hosted browsers, emulators, and simulators, and updates it when the UI changes. Teams use Momentic for regression suites in CI, test authoring from a code diff through the MCP server, and autonomous QA sessions with Mo. ## What Momentic does ### End-to-end web testing Preset steps and AI actions run on hosted browsers. Tests live as YAML in your repo, next to the code they verify. ### iOS and Android testing The mobile CLI drives iOS simulators and Android emulators. The same spec format covers web and mobile, so one suite covers the whole product. ### Self-healing tests Locators re-resolve when the UI moves, failure recovery patches the step, and permanent healing writes the fix back to the spec. Flaky tests go to quarantine instead of blocking the pipeline. ### Mo, the AI QA engineer Point Mo at a build and it explores the app, reproduces what it finds, and files bug reports. No test authoring required. ### Coding-agent integrations The momentic and momentic-mobile CLIs and MCP servers give Claude Code, Cursor, Devin, and other agents the ability to write and run real UI tests. ### CI and app graph Runs execute in GitHub Actions and other CI systems. The app graph tracks journey coverage so AI test selection runs the tests a diff actually affects. ## What makes Momentic different ### Tests are files, not a closed platform Unlike mabl or QA Wolf, every Momentic test is a YAML spec you own in version control. You review test changes in a diff like any other code. ### Built for coding agents Playwright MCP gives an agent a browser to drive. Momentic gives it a verification layer: authored specs, hosted runs, healing, and results it can read back. ### Web and mobile in one suite Playwright covers the browser and Appium covers devices. Momentic covers both, with the same step vocabulary and the same CI entry points. ### Maintenance is the product Selenium and Playwright suites decay as the UI changes. Momentic's auto-healing, failure recovery, and quarantine exist to keep the suite green without a human patching selectors. ### An agent that does QA, not a recorder that makes tests Mo explores a build the way a QA engineer would, then reproduces each suspected bug from a clean browser before reporting it. ## Who uses Momentic - Engineering teams that own quality in CI: developers and DevX engineers who write and maintain the suite, not a separate QA org. - B2B SaaS companies shipping daily: Notion, Xero, Webflow, Whatnot, Retool, Quora, Mutiny, GPTZero, Nuvo, CoverGo, Pocus, Coframe, Kibu, Roo, and Best Parents run Momentic in production. - Teams replacing Selenium or Playwright suites, or replacing outsourced QA platforms like QA Wolf and BrowserStack. - Mobile teams that need iOS and Android coverage without standing up Appium infrastructure. - Teams adopting coding agents that need the agent's output verified by real UI tests before merge. ## The team behind Momentic Momentic was founded in 2023 and is headquartered in San Francisco, California. The company is a Y Combinator W24 company. Wei-Wei Wu is co-founder and CEO. He previously built infrastructure and real-time features at Assembled, and was the first employee and founding engineer at Nashi, which Density acquired in 2021. Jeff An is co-founder and CTO. He built cloud and test infrastructure at Splunk, Google, and Robinhood after graduating from the University of Waterloo. ## How Momentic works - Authoring: plain-English prompts, the momentic-spec skill, or the web editor. Tests are YAML specs checked into your repo. - Execution: hosted browsers for web; iOS simulators and Android emulators for mobile. Local runs and CI runs use the same spec. - Results: run output lands in the dashboard and in CI. Mo bug reports include reproduction steps and artifacts. - Support: support@momentic.ai, and a shared Slack channel on paid plans. Sales and demos go through /sales. - Onboarding: the free tier needs no credit card. npx momentic init creates a project; the docs quickstart gets a first run in minutes. ## Key facts - **Company name:** Momentic - **Type:** Agentic quality platform (AI end-to-end test automation) - **Founded:** 2023 - **Founders:** [Wei-Wei Wu](https://twitter.com/wuweiweiwu) (CEO), Jeff An (CTO) - **Headquarters:** San Francisco, California, US - **Website:** [momentic.ai](https://momentic.ai) - **Core offering:** Plain-English tests the agent authors, runs on hosted browsers, emulators, and simulators, and keeps passing as the UI changes - **Pricing:** Free tier $0/forever; pay-as-you-go from $125/month + usage; enterprise custom.

How is Momentic different from Playwright? Playwright is a browser automation library; Momentic is a quality platform. Momentic tests are plain-English YAML specs with AI actions, self-healing locators, and permanent healing, and they run on hosted infrastructure for web, iOS, and Android with no framework code to maintain. Who founded Momentic? Momentic was founded in 2023 by CEO Wei-Wei Wu, previously an engineer at Assembled and the first engineer at Nashi, and CTO Jeff An, who built cloud and test infrastructure at Splunk, Google, and Robinhood. Momentic is a Y Combinator W24 company. What does Momentic test? Momentic runs end-to-end tests for web apps on hosted browsers and for iOS and Android apps on simulators and emulators. Mo, the AI QA engineer, also explores builds and files bug reports without any authored tests. Does Momentic work with coding agents like Claude Code? Yes. The momentic and momentic-mobile CLIs ship MCP servers that give Claude Code, Cursor, Devin, and other coding agents the ability to author and run real UI tests and read back the results.
