Feature flags
Each provider is profiled from its own pricing page, with the source recorded against every figure. One charges for the users you serve and states it does not charge for seats; one charges $75 a seat and does not charge for users. Between them, one bills every flag your app reads and one says reading flags is free however often you do it. The same team on the same product lands in a different order on each.
Feature flags
| Provider | Entry paid plan | Free allowance | What is metered |
|---|---|---|---|
| Flagsmith | $40 a month for Start-up paid yearly, or $45 monthly. That raises the allowance to 1,000,000 requests and three team members. | 50,000 API requests a month and ONE team member, with unlimited flags, environments and segments under a fair usage policy. | API requests. Every call your application makes to read flags counts, so the bill tracks traffic rather than team or audience — $50 per million above the plan's allowance, decreasing with volume. Seats are capped per plan on top: one on Free, three on Start-up. |
| LaunchDarkly | Not documented | Unlimited flags and unlimited seats, with 1,000 client-side MAU and 5 service connections a month, plus 100,000 experimentation MAU, 5,000 session replays and 5,000 errors. | Usage, explicitly not seats — the page says so in those words. $8.33 per 1,000 client-side monthly active users, where a unique user or device is one MAU, plus a charge per service connection, where one server-side SDK attached to one environment for a month is one connection. |
| Statsig | $150 a month for Pro, which includes 5 million events before the $0.05 per 1,000 overage starts. | 2 million events a month, unlimited flag and config checks, 50,000 session replays and unlimited seats — the most generous free plan of the four by a wide margin. | Analytics events, with flag and config checks excluded from the meter entirely — the plan table says "unlimited flag & config checks" on every tier. Pro includes 5 million events and charges $0.05 per further thousand. |
| Unleash | $75 per seat per month on pay-as-you-go. With no free plan behind it, a three-person team starts at $225 a month. | No free plan | Per seat, $75 a month each — the opposite axis to every other member here. Client-side MAU and service connections are unlimited on every plan, so audience size and traffic cost nothing; the bill is a function of how many people touch the tool. |
Which to consider
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.
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.
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.
A small team serving a large audience, and wanting the option to run it yourself. Client-side MAU and service connections are unlimited on every plan, so neither traffic nor audience moves the price — only headcount does, at $75 a seat.
