## Which should you choose?

Pick LaunchDarkly if A large team shipping to a small audience. Seats are explicitly unmetered — "no per-seat pricing", in its own words — so inviting everyone costs nothing, and the bill tracks the users you serve at $8.33 per thousand MAU. The free plan is $0 forever with unlimited seats and no card.

Pick Statsig if Wanting flags and experimentation on one bill without paying to read a flag. Flag and config checks are unlimited on every tier including free, and the free plan carries 2 million analytics events and 50,000 session replays — the most generous starting allowance here by a wide margin.

Consider something else: LaunchDarkly — Your audience is large relative to your team. MAU is the meter, so growth in users is growth in the bill, and the free plan's 1,000 client-side MAU is the tightest audience allowance of the four. There is also no published plan floor — the paid tier is usage-shaped and Enterprise is quote-only.

Consider something else: Statsig — You want flags and nothing else. The meter is analytics events, so you are buying an experimentation and product-analytics platform whose flags happen to be free; a team that only needs toggles is paying $150 a month at Pro for a surface it will not use.

## Documented by only one

- Entry paid plan: Statsig: $150 a month for Pro, which includes 5 million events before the $0.05 per 1,000 overage starts.
- Events included: Statsig: 2 million a month free, 5 million on Pro. Flag and config checks do not count against either — only analytics events do.
- Users included: LaunchDarkly: 1,000 client-side MAU a month on the free plan, then $8.33 per additional thousand. Experimentation carries its own separate allowance of 100,000 MAU at no extra charge.
