stamina is an opinionated Python library for retrying failed operations with production-safe defaults like exponential backoff with jitter, retry limits, and async/Trio support. It wraps Tenacity with a simpler, misuse-resistant API and built-in instrumentation and testing hooks.

Use cases

• retry failed HTTP requests in Python
• add exponential backoff with jitter to flaky calls
• retry async functions with asyncio or Trio
• limit retries by count and total time
• disable retries globally in tests
• instrument retry attempts with Prometheus or structlog

When to choose

• you want sensible, opinionated retry defaults without configuring Tenacity by hand
• you need both sync and async retry support with one API
• you want built-in observability and test controls for retries

When to avoid

• you need highly customized retry policies like custom wait strategies or per-call dynamic tuning
• you're not writing Python
• you prefer full control over retry internals that Tenacity directly provides
