Now you don't have to touch one ever again. Wei-Wei Wu CEO, Momentic We spent more than two years making test automation easier to build with Momentic. Now you don't have to touch one ever again. Customers kept telling us the same thing: "I don't want another script to write and maintain." and "I'm paying double, both for QA and now a testing tool that we have to use." Playwright, Selenium, Cypress - even modern testing tools still leave you with an artifact your team has to own. A framework your engineers and agents have to learn and keep in sync as your product evolves. For fast-moving teams shipping thousands of PRs daily, that's overhead you can't afford. **So we built Mo.** ## How Mo works Give it a URL or a build of your mobile app, and tell it what to test. That's it. You can also attach a PRD, Linear ticket, or Confluence doc when the agent needs more context. Mo launches hundreds of agents, works through the relevant user flows, explores thousands of permutations and edge cases, and records every interaction. Then it gives you the part you actually wanted from the start: a bug report. What was tested, what failed, reproduction steps, and video evidence of each one. **No script to write. No test suite to maintain. Your team does not have to do anything.** ## Why this matters now AI code generation has made shipping code exponentially faster. But testing hasn't caught up. There is still a massive verification bottleneck: how do teams make sure software still works for end users? Code is shipping at unprecedented volumes and breakneck speed, also introducing more bugs and incidents, which has vastly eroded the confidence that software actually works. When coding agents can spin up new features in hours, the last thing your team needs is to spend days writing test scripts that won't even cover half the edge cases. Mo changes that equation. Your agents write code. Mo bug bashes literally everything. Your agents review results and fix issues. Done. ## Try Mo today For the past few weeks, engineering teams at Notion, Glide, Superpower and others have been putting Mo through its paces on their own apps. Across the beta: Mo ran 1,100+ bug bashes and caught 3,500 verified bugs. Mo is free to try. Point it at your app, tell it what matters, and watch it test every single nook and cranny.

We already point a coding agent at Playwright. Why Mo? With Mo there's no test suite to write or maintain. Point it at each release, read the report, or hand the report to your coding agent. How many agents does Mo run at once? Hundreds on a single bug bash. Each agent gets its own hosted browser for web, or a simulator or emulator for a mobile build. How does Mo decide what counts as a bug? Every finding comes with a recording, repro steps, and Mo's reasoning. A suspected bug goes to a separate reproducer agent first, and a bug it cannot reproduce stays out of the report. What does Mo need to reach my staging environment? A URL or build our hosted browsers, emulators, and simulators can reach, plus a test account. Mo asks for credentials when needed, and they never leave the session. Can Mo run on pull requests? Yes. With the Momentic GitHub App installed, Mo scopes a session to the change, posts the result as a comment, and reports a status check you can require before a merge. A comment on the pull request also starts a scoped run. Can we keep the flows Mo tested as a suite? Yes, as Momentic tests. A flow Mo covered becomes plain-English steps in a YAML file in your repo. Your coding agent writes that file over our MCP server, and the CLI runs it in CI. How is this priced? Mo is self-serve. Sign up and you get $250 in Mo credits on us; after that, Mo runs on the same usage-based credits as the rest of Momentic. See [pricing](/pricing) for the rates.
