Korvo RelayOpen source

Put a local control plane between AI tools and runaway spend.

Relay meters, routes, and caps AI provider calls from your machine. Keep your credentials and usage ledger local while giving every coding tool the same enforceable budget boundary.

Core implemented; preparing for first release.

Control plane

One boundary for every model call.

Meter every call

Normalize token usage and cost into a local ledger so spend is inspectable before it becomes a surprise.

Enforce hard caps

Refuse requests before provider dispatch when a configured budget would be exceeded.

Route deliberately

Use aliases and provider-aware routing to choose the right model without coupling tools to one vendor.

Privacy

Local means local.

Environment-based credentials

Relay stores provider environment-variable names in local configuration and reads their values only when an adapter needs them. Secret values are never written to Relay's configuration or ledger.

No hosted account

Usage records and policy stay on your machine. Relay requires no account and sends no product telemetry to Korvo.

Roadmap

Shipping the auditable core first.

Implemented

Local metering, cap refusal, provider routing, ledger persistence, and mock provider conformance coverage.

First release

Official model and price verification, reconciliation workflows, expanded provider error conformance, and credential-gated smoke testing.

With partners

Team visibility and organization-wide policy controls are in development with design partners.

Copilot boundary

Relay governs the call. Your coding tool does the work.

Relay is not another coding agent and does not replace your editor or copilot. It is the local, provider-neutral boundary that meters each request, applies policy, and records the result before handing control back to the tool you already use.
