# Supported browsers and viewport presets

TestVibe runs browser tests through Playwright. The exact options available in a project come from its Playwright configuration, but most teams start with a small set of browser and viewport presets.

## Browser Choices

| Browser  | Use it for                                                                 |
| -------- | -------------------------------------------------------------------------- |
| Chromium | Default daily coverage for Chrome-like browsers.                           |
| Firefox  | Cross-browser checks for Firefox behavior.                                 |
| WebKit   | Safari-like coverage, especially for layout and mobile-sensitive behavior. |

Your repository may define named projects such as `chromium-desktop`, `mobile-webkit`, `staging-smoke`, or `debug`. Choose the configuration that matches the coverage you want for the run.

## Viewport Presets

| Preset           | Size        | Use it for                                               |
| ---------------- | ----------- | -------------------------------------------------------- |
| Mobile portrait  | `390x844`   | Phone layouts with narrow navigation and vertical flow.  |
| Mobile landscape | `844x390`   | Horizontal phone layouts and responsive menus.           |
| Tablet           | `820x1180`  | Tablet navigation, sidebars, and touch-friendly layouts. |
| Desktop 1080p    | `1920x1080` | Standard desktop validation.                             |

Teams can also define custom viewports in Playwright configuration.

## Choosing A Profile

| Goal                     | Recommended choice                                                                   |
| ------------------------ | ------------------------------------------------------------------------------------ |
| Fast everyday validation | Chromium with desktop 1080p.                                                         |
| Check responsive layout  | Mobile portrait and tablet.                                                          |
| Reproduce a user report  | Match the user's browser and viewport as closely as possible.                        |
| Prepare for release      | Run the important tests across desktop, mobile, and the browsers your users rely on. |
