Why teams choose izli.io

Built for real journeys

Record or define browser journeys, not just single pings. Every run shows exactly what your users see — with screenshots, steps, and timing.

One place for all checks

Browser, uptime, API, TCP, DNS, heartbeat — all in a single dashboard with consistent alerting and reporting.

Developer-first experience

Playwright-compatible, variables and secrets, exportable scripts, clean dark UI, and APIs for integrating into your pipelines.

Lightweight and affordable

Global-grade synthetic monitoring without Datadog-level complexity or pricing. Designed to scale from startups to enterprises.

Test real user flows with browser journeys.

Define or record end-to-end flows: logins, checkouts, dashboards, searches. izli.io runs them on a schedule and alerts you when something breaks.

  • Playwright-based journeys, recorded or hand-edited
  • Screenshots for every step, with timelines and performance
  • Baseline comparison and diagnostics when behavior changes
playwright-script.ts
test('login flow', async ({ page }) => {
// Navigate to login
await page.goto('/login');
// Fill credentials
await page.fill('#email', 'user@example.com');
await page.fill('#password', '********');
// Click submit and wait
await page.click('button[type="submit"]');
await expect(page).toHaveURL('/dashboard');
});
