DAU Growth Scaling Simulation

Model how your backend system evolves as your user base grows month over month. Uses Little's Law (N = λW) for connection demand and M/M/1 queuing for latency inflection. Choose your architecture tier to see architecture-specific capacity multipliers.

Growth Model

≥ 100

Daily active users at start.

Early stage: 1,000–10,000 · Growth: 50,000–500,000 · At scale: 1M+

0–200

Month-over-month DAU growth rate.

Stable: 5% · Fast: 15–20% · Hypergrowth: 50%+

1–10,000

Backend requests per active user per day.

3–36

Architecture

5–5,000
0–20
0–1

Fraction of requests that are reads.

≥ 0.1

P95 latency at initial DAU.

Storage Growth

≥ 0.1
0–100
≥ 1

Max storage for current architecture.
