Everything here exists. Most of it is open.

Tools for agents, evidence and ownership. Start with the problem you’re trying to solve, then look inside the build.

xNAUT / Agent terminal

A client said I never worked those hours. Now the tool proves it.

xNAUT runs a fleet of coding agents. Every action lands in a hash-linked record whose head is signed on a Securosys HSM in Switzerland. You verify it in your browser or with one line of OpenSSL. It never goes through me.

Check it at xnaut.dev/attest, or with stock OpenSSL against the published key. No account, no API, no xNAUT installed.
