Quick Answer
Playwright monitoring is the scheduled, automated execution of a Playwright browser test from outside your infrastructure, with an alert whenever the test fails. Dotcom-Monitor imports a Playwright for .NET test as a single .cs file (MSTest, NUnit, or xUnit) and runs it in Chromium from 30+ global locations or from a Private Agent inside your network. The same test serves functional testing and synthetic monitoring, so there’s no separate monitoring script to maintain. Building a new script just for monitoring? The EveryStep recorder is usually faster.
The Playwright Test You Already Trust, Now Running 24/7
Your Playwright for .NET test already knows how to log in, search, add to cart, and check out. Dotcom-Monitor runs that exact test on a schedule, records response times and failures, and alerts your team when it doesn’t complete.
- Playwright for .NET (C#) tests built on MSTest, NUnit, or xUnit.
- One .cs file in, reviewed in the editor, monitoring as soon as you save.
- Real Chromium browser on every run, with full JavaScript rendering.
- Secure Vault variables replace hardcoded passwords and API keys.
- Script Timeout turns a hung test into an alert, not a silent gap.

Write It Anywhere. Monitor It Here.
Playwright monitoring is built for teams that create browser tests outside Dotcom-Monitor. However the test was made, if it runs locally, it can run as a monitor.
Reuse End-to-End Tests
The login and checkout tests your QA team maintains for releases become production monitors without a rewrite. One test, two jobs.
Write It in Visual Studio or Rider
Keep scripting in the editor you know, with your own conventions, or record a starting point with Playwright’s codegen in C#. Import the file when it passes locally.
Generate It With AI
Describe the user journey to your AI coding assistant, get a Playwright for .NET test back, run it once, and import it.
Tip: Ask Your AI Assistant for a Test That Imports Cleanly
Write a Playwright for .NET test in C# using NUnit. Reference only Microsoft.Playwright and NUnit, with no other NuGet packages. Run it in Chromium. Open https://app.example.com, sign in, go to Reports, and assert that the “Monthly usage” chart is visible.
Most assistants default to TypeScript, so name the language and framework explicitly. Swap the password for a Secure Vault variable after import.
Choose by Where the Script Comes From
Both run real browser journeys and produce identical results. The difference is how the script gets made.
Import a Playwright Test
Best when the script already exists, or you want to own it in code.
- You have a working Playwright for .NET test today.
- Your developers prefer writing C# in their own IDE.
- You generate tests with an AI coding assistant.
- You want one test for functional testing and monitoring.
Record With EveryStep
Best when you need a brand-new script just for monitoring.
- No existing test to reuse.
- No coding required: click through the journey and the script is written for you.
- Usually the quickest path from idea to running monitor.
- Edit and replay right inside the recorder.

From .cs File to Running Monitor in Six Steps
Before you start, confirm the test is written with Playwright for .NET and passes in your local development environment.
Create a Playwright Device
Add a new monitoring device and choose the Playwright type.
Import Your Test
Upload the .cs file. It must use only Playwright and MSTest, NUnit, or xUnit.
Review the Script
Update environment-specific URLs, variables, and validations, and move credentials into Secure Vault.
Set the Script Timeout
Define, in seconds, how long a run may take before it ends and reports an error.
Choose Where and How Often
Pick monitoring locations, frequency, schedules, and alert groups.
Save and Start Monitoring
The first run starts immediately and appears in the Session Log. Later runs follow your schedule.
Full setup details are in the Playwright monitoring knowledge base article.
What Teams Monitor With Playwright Tests
QA Tests as Production Monitors
The end-to-end test that gates your release keeps checking production around the clock. No separate monitoring script to drift out of sync.
Login, Cart, and Checkout
Watch the journeys that make money as often as every minute, and get alerted when a step fails or slows down.
AI-Generated Checks
Turn a plain-language description of a critical flow into a Playwright for .NET test with your AI assistant, then run it on a schedule.
Regional Failures
Run the same test from 30+ locations to catch the CDN, DNS, or routing problem that only affects one part of the world.
Internal and Staging Apps
Install a Private Agent inside your network to monitor intranet apps, admin portals, and pre-production builds with the same test.
Third-Party Dependencies
Keep an eye on the embedded payment, identity, and search services your journeys rely on, from your users’ point of view.
Priced Exactly Like EveryStep Web Application Monitoring
Playwright devices use the same plans and rates as EveryStep monitors, and they’re included in the 30-day free trial.
A task is counted each time your test navigates to a different URL. Dotcom-Monitor calculates the task count after the first monitoring session, and shows the final count once the test completes without errors.
Example: How Tasks Are Counted
GotoAsync("https://shop.example.com"): 1 task- Search submits and loads
/search: 1 task - Click opens the product page: 1 task
GotoAsync(".../checkout"): 1 task
Clicks, typing, and assertions that stay on the same URL don’t add tasks. Illustrative only; your count appears after the first successful run.
Tests That Run Where Your Users Are
Run your Playwright test from 30+ monitoring locations across six continents, or inside your own network with a Private Agent. Alerts go straight to the tools your team already uses.

Playwright Monitoring Questions Teams Ask Before Signing Up
What Is Playwright Monitoring?
Playwright monitoring runs a Playwright browser test on a fixed schedule from outside your infrastructure and alerts you when it fails. With Dotcom-Monitor, you import an existing Playwright for .NET test, and it runs in a real Chromium browser from 30+ global locations, or from a Private Agent inside your network, as often as every minute.
Which Playwright Languages Are Supported?
Playwright for .NET (C#) only, for now. Tests written in TypeScript, JavaScript, Python, or Java can’t be imported. If your team works in those languages, you can ask an AI assistant to port a single test to Playwright for .NET, or record the journey with the EveryStep recorder instead.
Which .NET Test Frameworks Work?
MSTest, NUnit, and xUnit. Write the test the way you normally would for your framework of choice. It must run successfully in your local development environment before you import it.
What Exactly Do I Upload?
A single .cs test file. After import, the script opens in the editor so you can review it and update environment-specific values such as URLs, credentials, variables, or validations.
Can My Test Use Additional NuGet Packages?
No. Imported tests can only reference Playwright and the test framework (MSTest, NUnit, or xUnit). If your test relies on helper libraries or shared utilities, move the code it needs into the .cs file so the test is self-contained.
Which Browser Does the Test Run In?
Chromium only. If your test explicitly launches Firefox or WebKit, switch it to Chromium before you import it.
Should I Use Playwright Monitoring or the EveryStep Recorder?
Choose based on where the script comes from. If you already have a working Playwright for .NET test, or you prefer to write one in your own IDE or with an AI assistant, import it. If you need a brand-new script just for monitoring, the EveryStep recorder is usually quicker: you click through the journey in a browser and it writes the script for you. Results, pricing, locations, and alerting are the same either way.
Can I Use an AI Assistant to Write the Test?
Yes. Ask for a Playwright for .NET test in C# using MSTest, NUnit, or xUnit, with no other NuGet packages, running in Chromium. Run it locally to confirm it passes, then import the .cs file.
How Do I Keep Passwords and API Keys Out of the Script?
Use Secure Vault. After importing the test, replace hardcoded credentials in the editor with encrypted Secure Vault variables, just as you would in an EveryStep script. Values stay masked everywhere they appear.
Are the Results Different From an EveryStep Monitor?
No. A Playwright device produces exactly the same results as an EveryStep device, so reports, dashboards, alerts, and troubleshooting work the same way.
How Is Playwright Monitoring Priced?
Exactly like EveryStep web application monitoring, on the same plans. A task is counted each time the test navigates to a different URL. The task count is calculated after the first monitoring session and shown once the test completes without errors. See pricing for current rates.
What Happens If a Test Runs Longer Than Expected?
Each device has a Script Timeout, in seconds. If the test hasn’t finished within that time, the session ends and an error is reported, so a hung test becomes an alert instead of a silent gap.
Can I Monitor Internal Apps and Staging Environments?
Yes. Run the same Playwright test from a Private Agent installed inside your data center, VPC, or office network to monitor applications that aren’t reachable from the public internet.
Can I Try Playwright Monitoring for Free?
Yes, two ways. The 30-day free trial includes Playwright devices on the same terms as EveryStep web application monitors. The Free Forever plan also runs Playwright tests, with up to 25 targets, 2 monitoring locations, and 21 days of data retention.
