RailHub · the team hub

One ledger. One library. One switch.

RailHub is where a team's machines meet: sophisticated workflows with multi-level, airlocked human approval, every signed receipt in one place, a shared library, agents we run for you 24/7. It lives on railcall.ai, and it is the only thing you ever log in for.

Approvals that span machines

Airlocks on every machine; on the hub they become managerial steps: delegate while someone is out, require a quorum, separate who drafts from who sends, escalate.

The exact payload, staged, visible to the approver.

Approve

One human, a quorum, or a separated role, with an approve code for sensitive changes.

3

Execute

Runs on the machine with headroom; the receipt follows the work.

Cloud agents: $5 per trained agent. Free locally.

Trained agents we host so a job runs when every laptop is closed. Their thinking is still local-or-overflow; the $5 is for keeping them on. Build your own on your machines for $0.
