I was tired of pulling in 500KB just to retry a HTTP call — so I built my own

Your microservice calls an external API. It fails. You add Resilience4j. Now you have 10 transitive dependencies, a 500KB JAR, 3 config classes, and a @Bean method just to say "try 3 times, wait 1 second" . I hit that wall one too many times. So I built RetryKit — a zero-dependency Java 17 retry & circuit breaker library. No Spring required. No transitive pulls. JAR under 50KB. io.github.caninaam retrykit 1.0.1 Fixed delay retry with fallback — the most common case: String result = RetryKit
