Spring Boot 3 Rate Limits

Spring Boot 3 is a self-hosted application framework, not a hosted API. There is no provider-imposed rate limit on Spring Boot itself. Rate limiting is applied at the application layer using Spring Cloud Gateway, Bucket4j, Resilience4j, or upstream proxies, and is the responsibility of the team operating the deployed application.

Limits

Application-Defined application
varies
defined by the application built on Spring Boot
Spring Boot itself imposes no rate limits. Limits live in the application via filters, gateways, or middleware.

Policies

Self-Hosted Throttling
Spring Boot applications typically implement rate limiting via Spring Cloud Gateway's RequestRateLimiter (Redis-backed), Bucket4j token-bucket filters, Resilience4j RateLimiter decorators, or an upstream reverse-proxy / API gateway.
Actuator Endpoints
The Spring Boot Actuator endpoints (/actuator/*) are local management endpoints; access control should be enforced via Spring Security rather than rate limiting.
