gobreaker is a Go library implementing the Circuit Breaker pattern as a generic, configurable state machine. It prevents sending requests likely to fail by tracking failures and toggling between closed, open, and half-open states.

Use cases

• prevent cascading failures when a downstream service is down
• wrap HTTP calls to flaky external APIs with a circuit breaker
• stop hammering a failing database with requests
• add resilience patterns to Go microservices
• monitor service health via circuit breaker state change callbacks
• apply rolling-window failure counting to trip circuits

When to choose

• you write Go services that call unreliable network dependencies
• you need a small, focused, well-maintained circuit breaker library
• you want configurable trip conditions, exclusion rules, and state change hooks

When to avoid

• you need full resilience suites with retries, timeouts, and bulkheads (use something like resilience4j-style tooling)
• your project is not in Go
• you need distributed circuit breaker state shared across instances
