SAMPLE AC You’re watching RunProof prove AC-20 on saucedemo.com — a public sandbox we use to demonstrate the mechanism. Your real ACs run against your own live site, and produce the same kind of signed receipt.

Your regression suite takes six weeks. Watch this take ninety seconds.

Don't trust RunProof. Trust the receipt it hands you.

RunProof reads your acceptance criterion, designs the test, and runs it on your live site — producing a signed, content-hashed receipt your QA team can verify without us. The 90-second ceremony below is how the receipt gets made. Yours is yours to keep.
