Yes. ShipCheck is completely free with no signup, no watermarks, and no credit card required.

How is this different from TesterArmy or Playwright?

ShipCheck is a free, no-login tool for quick browser checks and visual diffs. Describe tests in plain English, get screenshots and reports instantly. Playwright is a framework you code against; ShipCheck handles the browser run for you.

Do I need to write code?

No. Write instructions in plain English like 'Click Get started' or 'Verify page contains Pricing'. ShipCheck converts them into browser actions automatically.

Are my tests stored on a server?

No. Test runs are ephemeral — results are returned to your browser and never permanently stored. Image uploads for visual diff are processed in-browser.

Can I compare screenshots too?

Yes. ShipCheck also includes a pixel-perfect visual diff tool — upload two images or paste two URLs to detect UI changes.

Yes. Notes on smoke tests and visual diffs are published at /blog on Tuesday and Thursday at 09:00 IST. A post stays unavailable until that time. The feed is /blog/feed.xml.

What sites can I test?

Any public HTTP/HTTPS website. In production, private IPs and localhost are blocked for security. When running ShipCheck locally (npm run dev), localhost URLs are allowed so you can test apps on your machine.

Public quotas for free browser testing tools

Burst + daily limits that protect the free tier without killing honest use.

A free browser tool without quotas will be used as someone else’s CI farm by lunch. Burst limits stop hammering; daily limits keep costs predictable. Return clear 429s with Retry-After so honest clients can back off.

Validate request bodies before you burn a slot — bad JSON should not count against the daily budget. That small reorder matters more than another marketing banner.

For the runtime side of the same free-tier story, see Playwright on Vercel Hobby.
