03Trace

## Follow one request across your whole backend.

Distributed tracing stitches a single operation across GraphQL, REST, gRPC, and background jobs. Walk the span waterfall down to the resolver that ran slow.

04Diagnose

## Move from symptoms to cause.

Start with an error spike, open the affected operation, inspect the trace, and find the failing stack frame without digging through disconnected logs.

05Compose

## Understand how your operations are executed.

Inspect distributed execution plans, see how work is split across services, and understand how one request becomes one response.

06Schema Governance

## Know the impact before you merge.

Nitro compares schema changes with published clients and gives teams a clear signal on what is safe, risky, or breaking.

07Delivery

## Ship with confidence.

Nitro turns release readiness into visible checks: schema validation, client compatibility, trusted operations, and rollout status.

Persisted operations

With strict trusted documents configured, production accepts registered operation IDs instead of arbitrary GraphQL documents.

08Workspace

## Give teams a shared workspace.

Explore schemas, run operations, validate documents, and keep important API work connected to the rest of Nitro.

Ready when you are

## Put your API on one control plane.

Start with production visibility, then add tracing, schema governance, client safety, and release checks as your team grows.
