## Which should you choose?

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.

Pick Flagsmith if Self-hosting, or a small team with modest traffic. It is open source with a documented self-hosted path, and Start-up is $40 a month billed yearly — the cheapest paid entry of the four. Identities and segments are unlimited, so your audience is never the thing that costs.

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.

Consider something else: Flagsmith — Your application reads flags often. API requests are the meter, so every evaluation is on the bill at $50 per million above the allowance — and the free plan's 50,000 requests a month is roughly one user refreshing a page a few thousand times. Seats are capped too: one on free, three at $40.

## Documented by only one

- Credit card to start: Statsig: No
- When the free offer ends: Flagsmith: The paid plans carry a 14-day free trial; the $0 plan itself does not expire.
- 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.
- Retention window: Statsig: 1-year analytics retention on the free plan; unlimited on Pro.
- Self-hostable: Flagsmith: Supported
- Users included: Flagsmith: Unlimited identities and segments under a fair usage policy. Flagsmith does not meter your audience at all — only the API requests your application makes to read flags.
