The exclusive hub for RailCall

Where your org runs on RailCall.

RailCall is free and runs on your own machines. RailHub is the one place your organization sees all of it, controls all of it, and pays for it once — priced per org, never per seat. Git is free; this is the hub.

The RailCall protocol

Machine-to-machine transactions on hardware you own. Human-approved, Ed25519-signed, verifiable offline. Unlimited machines, $0, and it never depends on RailHub.

What you get

The upgraded services, all of them.

Every capability below is org-level coordination on top of the free protocol. None of it is required to run agents. All of it is required to run a company that runs agents.

Visibility & control

4 capabilities
Org-wide auditability

Every signed receipt from every machine in one queryable view. Filter by user, machine, tool or time — answer “what did our agents do last Tuesday” in seconds.

Company kill switch

One button freezes every agent on every machine. Signed, recorded, reversible — and offline machines honor it on reconnect.

Shared policy & ledger

Write an approval policy once, enforce it on every machine. The shared ledger keeps the org’s receipt index consistent so no machine can quietly drift.

Cross-machine chains

One workflow that spans five machines is one signed chain — prove the whole path, not five disconnected fragments.

Approvals & governance

5 capabilities
Delegated approvals

An agent proposes, a different human approves. The moment a second person is involved, this is the layer that carries it.

Quorum approvals (M-of-N)

High-blast-radius actions require multiple signatures before they run. Two humans, one action, every signature receipted.

Separation of duties

The person who wrote the workflow cannot be the one who approves it. The control auditors ask for by name.

Routing & escalation

Approvals route to whoever is on call, escalate when they go stale, and auto-deny on a clock you set. No 2am bottleneck.

Blast-radius budgets

Cap what a team’s agents can touch or spend — and dry-run the blast radius before anyone approves.

Compute

2 capabilities
Internal compute routingFlagship

Route agent work to the machines in your org that actually have headroom. Idle-aware, owner-preempting, and every routed job still mints a receipt.

Always-on node

A hosted machine that joins your fleet as just another node, so flows keep running when laptops close. Same protocol, same airlock, still your keys.

Evidence & compliance

4 capabilities
Evidence packs

One auditor-ready bundle covering all users and any date range — signed receipts, approval chains, policy versions, exported and verifiable offline.

Compliance attestation

Who approved what, by role and period, attested with a signed statement backed by the receipt chain. Not a spreadsheet someone maintained.

Evidence archive

Long-term org-wide retention of receipts and packs. Immutable, exportable, verifiable years later — your audit trail outlives any laptop.

Outside-auditor anchoring

Independent countersignature on the receipts you choose: proof an outsider can trust without having to trust you.

Access & payments

5 capabilities
Centralized payments

One bill for the whole org — machines, teams, marketplace purchases — settled in one place. The billing convenience of cloud, on hardware you already own.

Scoped credential vault

Teams run with org credentials no member can read. Values stay sealed; receipts still prove who used what, and when.

Private module registry

Your internal modules and workflows, visible only to your org. Private repos — for agent capability.

Guest access with expiry

Time-boxed, scoped access for contractors and auditors. It expires on its own; the receipts remain.

Shared runbooks & templates

Publish vetted workflows to the whole org. New machine, new hire, same governed playbook — pulled from your library, not rebuilt from scratch.
