Render Private Services

Private services are identical to web services except they have no public URL. They are reachable only by other Render services on the same private network (same region + workspace). Use them for internal APIs, microservices, gRPC servers, sidecar processes, and anything that should never face the internet.

When to Use

• Building an internal API or microservice behind a public gateway
• Running a gRPC, TCP, or other non-HTTP server that only your services call
• Deploying infrastructure components (Elasticsearch, ClickHouse, RabbitMQ)
• Choosing between a private service and a background worker

For public-facing HTTP services, use render-web-services. For services that don't receive any traffic, use render-background-workers.
