Human version

Arca Vision

Software for missions that matter. Local-first software for humans and AI agents. We ship products and take on the work that needs a written trust boundary.

TWO TRACKS

ARCA is our first product: a password manager for macOS and Windows, for business and consumer use. More products will be listed as they ship.

We take on software work for organizations that need it built. That includes government contracting through RFPs on SAM.gov. Government is one customer segment, not the company.

ARCA is live.

The local secrets manager for humans and AI agents. Free vault. $0 forever. No cloud. No account.

Local by default. One portable encrypted file on your machine. No account. No backend.

Nothing in the prompt. Inject secrets into the child process. The model never holds the token.

Built for agents. Dummy env in the prompt. Real credentials only in the wrapped process.

Mac and Windows today. Universal DMG and Windows installer. Linux GUI is coming.
