Exponential Backoff & Jitter Visualizer

Simulate retry delay schedules with and without jitter, and see how client herds pile onto the same tick without randomization.

Exponential Backoff & Jitter

Compare full, equal, and decorrelated jitter retry schedules — see how spreads avoid thundering herds.

Strategy Base delay (ms) Multiplier Max delay (ms) Attempts Clients (herd)

AWS architecture blogs recommend full jitter for most cases: random(0, min(cap, base * 2^attempt)). Decorrelated: min(cap, random(base, prev*3)).

Strategies

Strategy	Formula (simplified)
No jitter	`min(cap, base * multiplier^attempt)`
Full jitter	`random(0, exp)`
Equal jitter	`exp/2 + random(0, exp/2)`
Decorrelated	`min(cap, random(base, prev * 3))`

Full jitter is usually the best default for widely distributed clients hitting the same dependency.
