Claude Apps Gateway: Self-Host Claude Code's Governance Layer on Bedrock, Google Cloud, or Foundry

Anthropic released Claude apps gateway on June 29, 2026. If you’ve been running Claude Code in a team of more than a few people and noticed there’s no good way to control who spends what, where inference goes, or how policy is enforced across developers — this is the piece that was missing.

What It Solves

The governance gap in Claude Code enterprise rollouts has been consistent: individual developers authenticate directly to inference, credentials live on developer machines, there’s no central policy, and finance can’t see per-user costs until the bill arrives.

The Claude apps gateway closes all of that. It’s a self-hosted service that sits between your developers’ Claude Code clients and your model provider. Developers sign in via corporate SSO. Admins define policy in one place. Spend caps apply per org, group, or user. And inference traffic routes through your cloud account — not Anthropic’s — if you’re on Bedrock, Google Cloud, or Microsoft Foundry.

Architecture

The gateway is a single stateless container running on Linux, backed by a PostgreSQL database. Configuration lives in one file, gateway.yaml, which defines:

Where the gateway listens
How developers authenticate (OIDC issuer)
Where inference goes (upstream provider)
What policy and telemetry settings apply

Because the container is stateless, you can run it behind a standard load balancer with no sticky sessions. Scale it horizontally if you have many developers; run it as a single instance if you don’t need HA. PostgreSQL holds session state, usage records, and policy definitions.

Supported upstreams:

Amazon Bedrock
Claude Platform on AWS
Google Cloud
Microsoft Foundry
Anthropic API (fallback — see data residency note below)

Identity and Authentication

The gateway acts as an OpenID Connect relying party. It works with:

Google Workspace
Microsoft Entra ID
Okta
Any standards-compliant OIDC provider

Developers log in once — their existing corporate identity — and the gateway issues a short-lived session. No long-lived credentials sitting on developer machines, no per-developer API key rotation.

Getting started:

# Download the Claude Code CLI binary
# Point gateway.yaml at your OIDC issuer and upstream credential
# Register one OIDC app in your IdP

That’s the setup surface. Anthropic’s own docs at code.claude.com/docs/en/claude-apps-gateway walk through the full configuration reference.

Spend Control

Admins can set spend caps that apply daily, weekly, or monthly, and scope them at three levels: organization, group, or individual user.

The gateway enforces caps per-request — requests that would exceed the cap are rejected before they hit the upstream provider. Policy is defined on the server; clients pick it up automatically at sign-in. No per-developer configuration required.

Data Residency

If you route through Bedrock, Google Cloud, or Foundry: inference traffic goes from your developers to your cloud account. It does not pass through Anthropic’s infrastructure. Usage data stays put.

The gateway itself doesn’t send inference traffic or usage data to Anthropic unless you configure it to use the Anthropic API directly. That’s the fallback upstream — and if you use it, the data residency guarantee goes away.

Trap: Automatic failover routing can switch between providers if you configure multiple upstreams. If your data residency requirement is real (compliance, not preference), either disable failover to the Anthropic API or don’t configure it as a fallback.

Open Protocol

Anthropic published the protocol the gateway uses. Third parties can implement their own gateways that support the same SSO, policy, and spend-cap features. This is an interoperability move — it determines whether Claude apps gateway becomes the de facto standard for multi-cloud Claude Code governance, or stays one implementation among several.

The protocol reference is at code.claude.com/docs/en/llm-gateway-protocol. If you’re evaluating LiteLLM, TrueFoundry, or other LLM gateway products alongside the Anthropic gateway, check their protocol compliance — partial implementations may miss policy enforcement.

Things That Catch Builders

Spend caps apply on the next request, not retroactively. If a developer submits a large workflow that generates 50 sub-requests in parallel, the cap check happens per-request. Set caps before developer onboarding, not after an overrun.

IdP downtime = Claude Code outage. The gateway issues short-lived sessions against your identity provider. If your IdP is down, developers can’t authenticate. Plan your HA accordingly — this is the same dependency shape as any SSO-gated corporate tool, but worth making explicit.

Policy enforcement at sign-in. Managed settings are pushed to clients at authentication. If you change policy mid-day, developers running long sessions with cached tokens may not pick up the change until their next sign-in. Short token TTLs reduce this window.

Protocol compliance varies across third-party gateways. Anthropic’s gateway is the reference implementation. Others may implement a subset. Test policy enforcement — specifically spend caps and managed settings propagation — before relying on a third-party implementation for compliance purposes.

Who Should Deploy This

You need it if any of these are true:

Your security team has blocked Claude Code rollout over credential management
You need to route inference through Bedrock or Google Cloud for data residency
You want cost attribution by developer or team before the monthly bill
You’re rolling out to more than one team and need centralized policy

You don’t need it yet if you’re a solo developer or a small team where direct API key use is fine and cost visibility is good enough from your Anthropic billing dashboard.
