Cheapest MAU-metered platform as your audience grows
LaunchDarkly, Unleash and ConfigCat compared at your current seats — only MAU changes per row. Statsig isn't MAU-metered at all, so it's shown separately above; watch how LaunchDarkly's rank flips once MAU clears the crossover point.

Why MAU-metered, seat-based, flat-fee and freemium-analytics billing shapes matter
Feature flag platforms don't compete on a single price — they compete on which dimension of your product they choose to meter. LaunchDarkly's Foundation/Pro pricing bills (client-side MAU / 1,000) × MAU rate + seats × seat rate, so cost scales directly with how many end users see your app, on top of a flat per-developer charge. That shape is brutal for a consumer product with a huge audience and a small engineering team — exactly the profile where MAU fees dwarf seat fees. Unleash flips that entirely: it charges seats × seat rate with no MAU or connection metering at all, so its bill stays flat no matter how large your user base grows — great for high-traffic products, less competitive for a large team that only ships flags to a small audience. ConfigCat goes further still, selling a flat unlimited-seat monthly plan that ignores both MAU and headcount and meters config-JSON downloads instead — the most budget-predictable shape of the three, and the one most likely to win once MAU passes a fairly low threshold.
Statsig is the outlier: flag and config checks are unmetered and free, and a generous multi-million-event allowance covers the analytics/experimentation side of the product before any charge appears. A team running simple on/off or percentage-rollout flags without heavy experiment analytics can realistically pay close to $0/month — but the moment analytics-event volume passes the free tier, cost is billed per additional million events, a shape that has nothing to do with MAU or seats. There is no vendor whose sticker price represents your bill without knowing which dimension — audience size, team size, or event volume — your usage actually stresses.
How this calculator works
The Feature Flag Platform Cost Calculator compares four vendor pricing shapes — LaunchDarkly (MAU + seat metered), Unleash (seat-only), ConfigCat (flat unlimited-seat fee) and Statsig (free flags, metered analytics events) — at your monthly active users, team size and event volume. LaunchDarkly's cost is (MAU / 1,000) × MAU rate + seats × seat rate; Unleash is seats × seat rate with no MAU charge; ConfigCat is a flat monthly fee regardless of MAU or seats; and Statsig is max(0, events - free allowance) × price per million events, meaning it's $0 whenever your analytics volume stays under the free tier. The calculator shows all four totals side by side, then a separate table isolates LaunchDarkly, Unleash and ConfigCat across a range of MAU values at your current seat count, so you can see exactly where LaunchDarkly's rank flips from competitive to expensive as audience size grows.
These are representative pricing shapes based on typical published ranges, not live vendor quotes — actual LaunchDarkly, Unleash, ConfigCat and Statsig pricing varies by plan tier, contract term and negotiated enterprise terms, and all four vendors offer custom enterprise pricing above their published self-serve tiers. Always confirm current pricing directly with the vendor before budgeting.
Frequently asked questions
How much does a feature flag platform cost in 2026?
It depends entirely on which dimension the vendor meters. LaunchDarkly's Foundation plan is roughly $8.33 per 1,000 client-side MAU per month plus about $12/seat/mo on Pro, so a 100,000-MAU app with 8 developers lands near $900-1,000/mo. Unleash bills per seat with no MAU charge, ConfigCat sells a flat unlimited-seat Pro plan around $110/mo regardless of MAU, and Statsig leaves flag checks unmetered and free up to a generous analytics-event allowance. These are representative published ranges, not live quotes — always confirm current pricing with the vendor before budgeting.
Why does LaunchDarkly get so expensive at high MAU while Unleash and ConfigCat don't?
LaunchDarkly's Foundation/Pro pricing meters client-side monthly active users, so cost scales linearly with your app's audience size on top of a per-seat charge — a consumer app with millions of MAU can rack up thousands of dollars a month in MAU fees alone. Unleash charges per developer seat and doesn't meter MAU or service connections at all, so its bill stays flat as your user base grows. ConfigCat goes further and ignores both MAU and seat count, selling a flat monthly fee that includes unlimited seats and meters config-JSON downloads instead. That's why a high-MAU, small-team product can flip from LaunchDarkly being reasonable to being by far the most expensive option as its audience grows.
Is Statsig really free for feature flags?
For flag and config checks specifically, yes — Statsig leaves flag evaluation unmetered and bundles a multi-million-event free tier for the analytics/experimentation side of the product. A team that only uses basic on/off or percentage-rollout flags without heavy experimentation analytics can realistically run at or near $0/month. Cost only appears once your analytics or experiment-event volume grows past the free allowance, and it's billed per additional million events rather than per MAU or per seat — a fundamentally different shape from LaunchDarkly, Unleash or ConfigCat.
Which feature flag platform is cheapest — LaunchDarkly, Unleash, ConfigCat or Statsig?
There's no universal winner — it flips based on which dimension your usage stresses. LaunchDarkly tends to win only at low MAU where its per-seat cost undercuts a flat fee; ConfigCat's flat rate wins once MAU climbs past a fairly low threshold; Unleash wins for teams with very few seats and no interest in a flat unlimited plan; and Statsig wins outright for flag-heavy, analytics-light workloads regardless of MAU or seats. Run your own MAU, seat count and analytics-event volume through the calculator above rather than assuming a vendor's headline price represents your bill.
