backon is the modern successor to `backoff` with zero dependencies and features like circuit breaker, hedging, rate limiter, generator retry, and 4 different APIs. `stamina` is an opinionated wrapper around `tenacity` that provides safe defaults but doesn't add new functionality. backon is more feature-complete and standalone; stamina is more conservative and depends on the tenacity ecosystem.
