Failsafe-go is a Go library for building fault-tolerant applications by wrapping functions with composable resilience policies. It provides retry, fallback, circuit breaker, rate limiter, bulkhead, timeout, hedge, cache, and adaptive load-limiting policies.

Use cases

• retry failed HTTP requests with backoff
• add a circuit breaker around flaky downstream services
• limit concurrent calls with a bulkhead
• add timeouts to slow operations
• fall back to a backup connection on failure
• rate limit outgoing API calls
• hedge slow requests with duplicate calls
• compose multiple resilience policies around a function

When to choose

• you need composable resilience patterns in Go
• you want retry, circuit breaker, and rate limiting in one library
• you need adaptive load limiting based on latency or failures
• you want synchronous and asynchronous execution with policies

When to avoid

• you need service-mesh-level resilience across services
• you want a proxy-based solution without code changes
• your stack is not Go
