> Canonical: https://antifailure.dev/request-demo > Book thirty minutes with the person building Antifailure. Bring a deployment your team is nervous about and see what a disposable production twin catches before it ships. The engine is open source and runs on your own machine without an account at all. # Request a demo Know what happens before you deploy. - A disposable production twin Every risky change runs against an isolated, production-shaped copy, then the copy is torn down. - Fail closed, customer-hosted Production data stays inside your boundary. An unverified golden cannot be branched, and the twin has no route out. - Evidence, not a green checkmark Every verdict arrives with the rows it read, the trace it took and a recording of the attempt, so a reviewer can check it. # Request a demo Tell us who you are and what you run, and we set up a walkthrough on a deployment your team is nervous about. A person reads every request and replies to arrange a time. It is stored in the product database, read by a person, and never sold or added to a newsletter. Already have an organization? Sign in with GitHub and you land in the one you belong to. The engine itself needs none of this. It is open source, it runs entirely on your own machine, and the quickstart goes from nothing to a working environment without an account.
