The hard boundary for outbound AI

The AI VPN for controlled outbound traffic.

Redact sensitive fields, enforce provider boundaries, and control costs before prompts, files, and runtime context leave your environment.

Spendplane sits between your tools and every model provider as the mandatory request boundary for policy, routing, and observability.

Intercept. Sanitize. Route.

at the edge.

One control surface replaces direct provider calls with a reviewable, cost-aware outbound path.

Zero-latency pattern matching
Support for 24+ model providers
SOC2 compliant audit logging

Redaction

PII, keys, and custom patterns are detected before egress.

Boundary control

Only approved providers and lanes are reachable from the request path.

Cost governance

Budget ceilings and downgrade rules apply before the call is made.

Auditability

Every request leaves with a trace, a policy decision, and a destination.

Request lifecycle

One pipeline between your environment and every model.

STAGE 01

Ingress

Apps, IDEs, and agents send one OpenAI-compatible request into Spendplane.

STAGE 02

Inspection

Headers and payloads are checked for secrets, PII, and policy violations.

STAGE 03

Decision

Routing, budget, and provider rules determine the allowed lane.

STAGE 04

Execution

Only the cleaned and approved payload reaches the selected provider.

Provider abstraction

One gateway, every model.

Your builders deserve a real boundary, not another promise.

Route outbound AI traffic through one controlled layer before it reaches a provider, then scale with clearer policy and visibility.
