Playground

Tune the core options against a simulated flaky request and watch every attempt land on the backoff timeline, to scale, in real time. Each feature also has its own focused demo in the guides — this one puts the main knobs together.

• failed

• bailed
• pending
• succeeded

failUntil sets how many attempts fail before success; bailAt throws a BailError on that attempt.

For the polling (until), hung-attempt (attemptTimeout) and Retry-After (getDelay) behaviours, see the dedicated demos on the Poll until done, Per-attempt timeout and Server-driven delay pages.
