01
Install Momentic
One command. Installs the CLI, initializes the project, points it at your app, and runs a sample browser test.
Describe the behavior you want to check in plain English. Momentic turns it into an end-to-end test, runs it in a real browser, and updates it when your UI changes. No selectors to maintain.

From an empty repo to a passing browser test, without standing up another test framework.
01
One command. Installs the CLI, initializes the project, points it at your app, and runs a sample browser test.
02
Describe what the user does and what should happen next. Momentic turns that into browser actions and saves the test as YAML next to your code. It adds no XPath, no CSS paths, and no test IDs to your app.
03
Same command on your laptop and in CI. Wire it to pull requests, nightly regression runs, and release gates.
Plain-English authoring, real browsers, self-healing locators, and a CLI that runs the same way on your laptop and in CI.
Write tests in plain English. Log in, complete checkout, verify the dashboard total. Momentic turns each line into an executable step anyone on the team can read.
Engineers and coding agents write the tests.
Assert on what the user sees: color, layout, image content, and position on screen, next to the usual element and text checks.
Assertions on the rendered screen.
Momentic re-resolves targets when elements move, waits for the page to settle instead of sleeping, and caches the path that worked. Over 99% of steps replay from that cache, 52ms slower than the equivalent Playwright call in our benchmark, so the AI cost is paid once, not on every run.
UI refactors don't break your test suite.
Tests drive Chromium, Google Chrome, or Chrome for Testing, on your machine or on hosted browsers. Real rendering, real network, real cookies.
The browser your users have, not a jsdom shim.
Run the suite from the CLI, shard it across CI jobs, and gate pull requests and deployments on the result.
Get feedback while the change is still fresh.
Intercept requests, return fixed data, override feature flags, or force a 500 so you can test the states a live backend won't give you on demand.
Test the edge cases before your users find them.
Cursor, Claude, and Codex can author, run, and debug tests against a live browser through MCP, from inside your editor.
Your agent writes the test. You review the diff.
Trusted by teams that ship every day.
Engineering teams use Momentic to retire manual regression passes, cut flaky-test maintenance, and catch regressions on the pull request.

Same authoring model. Same APIs. Same test files.
Checking that a browser app still works for the people using it: sign-in, forms, navigation, checkout, and the API calls behind them, end to end in a real browser.
The same browser steps run by software instead of by a person. It pays off on regression suites, on pull-request checks, and on the release checklist somebody currently clicks through by hand.
You describe the behavior in plain English. Momentic reads the page, performs the interactions, checks the result, and caches the path that worked so the next run is fast and repeatable.
No. Describe the element or the interaction in plain English, and Momentic resolves it from the page as rendered.
Momentic combines intent-based targeting with auto-healing and smart waiting. It re-resolves changed targets, waits for page, DOM, network, and navigation activity to settle, and recovers from a transient interruption, so a marketing popup does not fail an otherwise valid test.
Momentic currently supports Chromium, Google Chrome, and Chrome for Testing. By default tests run on browsers on your own machine or CI runner; hosted Chrome browsers move execution to Momentic-managed infrastructure with unlimited concurrency. See the documentation for the current list of supported browsers.
Yes. The same CLI command runs locally and in CI, so you can gate pull requests, run nightly regression, and check a deployment.
Yes. Tests execute in parallel to shorten feedback time as the suite grows. Hosted browsers remove the local machine limit, so concurrency is not bound by your runner's CPU.
Yes. Momentic intercepts requests and returns responses you define, so you can use fixed data, override a feature flag, or force a 500 that a live backend will not give you on demand.
Yes. Cursor, Claude Code, and Codex create, edit, run, and debug tests through the Momentic MCP server, from inside your editor.
Traditional frameworks define tests through code and selectors, so maintenance grows with every UI change. Momentic authors tests in natural language, resolves targets from the rendered page, and self-heals when elements move. See the Playwright and Selenium comparisons for a detailed breakdown.
No. Momentic is built for engineers and for coding agents. Steps are plain English, every test is a YAML file in your own repository, the CLI runs it and CI gates it. There is a visual editor, and it writes that same YAML, so it is one way in rather than the product itself.
