# Zerocheck vs building your own

Compare building the exact test infrastructure your team wants with adopting a service for the browser checklist you already run.

## What In-house does well

- You control the test runner, data handling, scheduling and reporting.
- You can build specialized browser or non-browser behavior for your application.

## What to evaluate with In-house

- Include initial implementation, maintenance, upgrades and failure triage in the ownership estimate.
- A service saves you from building some workflow pieces, but adds a vendor dependency and a defined supported scope.

## How Zerocheck differs

- Start in the web app: describe the user flow and expected outcome, then review the drafted steps and real browser result.
- Save and edit tests in the web app, or download individual YAML tests to run with the optional CLI, on your machine or in an existing CI job.
- Open a run to see each step's screenshots, console errors and the exact steps that ran. A recording is available when no credentials are configured.

## Side by side

| Feature | In-house | Zerocheck |
| --- | --- | --- |
| Control | Your own architecture and infrastructure | Configurable tests within the supported browser workflow |
| Data handling | Defined by your implementation | Your instance makes every decision and model call; CLI runs send it the selected tests and what the browser shows |
| Starting point | Build or extend the test harness | Draft and run one checklist item in the web app |

## Frequently asked questions

### How should I compare Zerocheck with In-house?

Use the same real user flow, test data and expected outcome. Inspect one passing run, one intentional product failure and one harmless UI change. Compare setup, review effort and supported scope.

### What does Zerocheck include?

Zerocheck is US$500 per month, with US$500 in credits at sign up: a dedicated instance for your team, with hands-on setup of your first tests. About 1,000 test runs a month are included; more by agreement. It is month to month, and you can cancel at any time. Your team supplies the app, test accounts and expected outcomes.

### Can I keep my existing test suite?

Yes. Evaluate Zerocheck alongside it for selected browser flows. There is no automatic migration or import of another framework’s test code.
