I TESTED 11 HTTP RESILIENCE LIBRARIES

Summary from the TLDR IT newsletter

An engineer tested eleven HTTP resilience libraries against a suite of twenty-one conformance scenarios covering retries, timeouts, circuit breaking, bulkheads, hedging, and request deduplication. The results showed that while basic single-policy features like standard retries pass universally, combining policies or handling concurrent events like caller cancellations during backoffs exposes widespread correctness failures across most implementations.
