Why copilotbrowser?

Everything you need for reliable browser automation and testing.

Cross-Browser

One API for Chromium, Firefox, and WebKit on every OS.

Auto-Wait

Smart waiting for elements, navigation, and network — no flaky sleeps.

Test Runner

Parallel execution, fixtures, assertions, retries, and sharding built in.

Traces & Screenshots

Capture videos, screenshots, and rich execution traces for debugging.

Network Control

Intercept requests, mock APIs, and modify responses on the fly.

Device Emulation

Test mobile viewports, geolocation, permissions, and dark mode.

Automate, debug, and ship — at every scale.

AI-ready browser automation that works where you do.

Test with confidence, not complexity.

copilotbrowser's built-in test runner handles parallel execution, smart retries, fixtures, and assertions out of the box. Auto-waiting means no more arbitrary sleeps — your tests stay green because they actually wait for the right moment.

Writing Tests →Assertions →
test('login works', async ({ page }) => {
  await page.goto('/login');
  await page.getByLabel('Email').fill('user@example.com');
  await page.getByRole('button', { name: 'Sign in' }).click();
  await expect(page).toHaveURL('/dashboard');
});

Debug faster with traces and time travel.

Every test run captures a rich execution trace — DOM snapshots, network requests, console logs, and action timelines. Open the Trace Viewer to replay exactly what happened, step by step, without re-running anything.

Trace Viewer →Screenshots →
// Capture a trace for every failed test
use: {
  trace: 'on-first-retry',
  screenshot: 'only-on-failure',
  video: 'retain-on-failure',
}

Deploy everywhere. Integrate with anything.
