01
Install Momentic
Add Momentic to your project, configure your application, and launch your first browser test from the CLI or local editor. There is no separate automation framework to build from scratch.

Web app testing that doesn't break when your UI changes.
Describe the user behavior you want to validate in plain English. Momentic turns it into a reliable end-to-end web test, runs it in a real browser, and keeps it working as your application changes. Write less test code, maintain fewer brittle selectors, and catch more regressions before they reach production.

How web automation testing works.
Go from setup to reliable automated web testing without building and maintaining another testing framework.
02
Author tests in plain English
Describe what a user should do and what should happen next. Momentic translates the instructions into browser actions and stores each test as a readable file alongside your code — no XPath, no fragile CSS paths, and no test IDs added to your app.
03
Run locally or in CI
Run the same tests while developing locally or as part of your CI pipeline: on pull requests, scheduled regression suites, and release workflows.
Web test automation features.
Momentic combines AI-powered authoring, real browser execution, self-healing tests, and engineering-native workflows in one automated web testing tool.
Natural-language web test authoring
Describe actions such as logging in, completing checkout, editing an account, or verifying a dashboard state in plain English. Momentic turns those instructions into executable steps your whole engineering team can read.
Test user behavior, not selector implementation.
Visual and multimodal assertions
Verify what users actually see, not just what the DOM contains. Assert on color, layout, image content, and on-screen position alongside standard element checks.
Test what's on the screen, not just what's in the code.
Self-healing web tests
Your UI will change; your suite should not break because of it. Momentic re-resolves intended targets when elements move, waits for the page to stabilize, and caches successful targeting for future runs.
Keep valid tests green as your UI evolves.
Real browser test execution
Validate your application in an actual browser instead of relying only on mocked component behavior. Run end-to-end user journeys against Chromium, Google Chrome, or Chrome for Testing.
Test the experience your users actually interact with.
Parallel testing and CI/CD execution
Turn every important code change into an automated quality check. Run tests from the Momentic CLI, execute many tests in parallel, and add the suite to pull requests, deployments, or scheduled regression workflows.
Get feedback while the change is still fresh.
Network and API request mocking
Intercept requests, return controlled data, override feature flags, or force error responses so the frontend can be validated against states that are expensive to reproduce against a live backend.
Test the edge cases before your users find them.
MCP support for coding agents
Momentic's MCP server lets compatible coding agents create, edit, run, and troubleshoot tests against a live browser from your development environment.
Let your coding agent create and verify the test.
Web test automation that helps teams ship with confidence.
Engineering teams use Momentic to replace repetitive manual QA, reduce flaky test maintenance, and catch important regressions earlier.

Web app testing, answered.
What is web app testing?
Web app testing validates that a browser-based application works correctly for real users. It covers functional testing, end-to-end testing, regression testing, UI testing, authentication flows, form validation, API interactions, and other critical user journeys.
What is automated web application testing?
Automated web application testing uses software to execute repeatable browser interactions and verify expected outcomes without a person performing every test by hand. It is most valuable for regression suites, critical user journeys, pull-request validation, and repetitive release checks.
How does Momentic automate web app testing?
You describe the behavior you want to test in natural language. Momentic interprets the application state, performs the required browser interactions, verifies the result, and stores successful targeting information so future runs stay fast and repeatable.
Do I need to write XPath or CSS selectors?
No. Instead of tying every action to a hand-maintained selector, describe the intended element or interaction in natural language and Momentic resolves the target from the current page.
How does Momentic reduce flaky web tests?
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 transient interruptions — so a marketing popup does not fail an otherwise valid test.
Which browsers does Momentic support?
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.
Can Momentic run web tests in CI/CD?
Yes. Momentic web tests run through the CLI locally or in CI, which makes them suitable for pull-request checks, scheduled regression suites, and deployment workflows.
Can Momentic run tests in parallel?
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.
Can Momentic mock APIs and network requests?
Yes. Momentic intercepts network requests and returns controlled responses, so teams can test with fake data, override feature flags, force error states, and validate scenarios that are hard to reproduce against a live backend.
Can coding agents create Momentic web tests?
Yes. Momentic provides an MCP server that lets compatible coding agents create, edit, run, and troubleshoot tests from the development workflow.
How is Momentic different from Playwright, Selenium, or Cypress?
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.
