LaunchDarkly Alternatives 2026: Feature Flag Prices Compared

For 10 developers, 100,000 monthly users and 50 flags, LaunchDarkly's Foundation plan costs about $833 a month, billed yearly. PostHog and Statsig cost nothing for flags on their free tiers, and ConfigCat Pro is the cheapest paid plan at $110 a month. These are list prices from each vendor's pricing page, read on October 10, 2026.

Leaving LaunchDarkly mostly saves money when the bill grows with your users. LaunchDarkly does not charge per seat. It charges per 1,000 client-side monthly active users and per server connection, so a small team serving a large app pays the most. Toolradar data: Toolradar tracks 22 feature flag tools, and it lists LaunchDarkly as an alternative to 20 other tools as of October 2026. For the wider field, including Unleash, see the feature flag platforms ranking.

Cost at the scenario

The scenario is 10 developers, 100,000 monthly active users, 3 server connections, 50 flags and 100,000 flag requests a month. The table shows monthly list cost, cheapest first.

Tool	Entry price	Cost at scenario	Free plan	What the bill counts	Watch for
PostHog	Pay as you go, no base fee	Free	1M flag requests and 1M product events a month, 1 project	Flag requests and events	$0.0001 per request above 1M
Statsig	Pro, $150 a month	Free (flags only)	2M metered events, unlimited flag checks, unlimited seats	Metered events, not seats	$0.05 per 1K events above 5M on Pro
ConfigCat	Pro, billed monthly	$110	10 flags, 5M config downloads	Config downloads; seats and users unlimited	Pro caps the account at 100 flags
GrowthBook	Pro, $40 per seat a month	$400	Starter, up to 3 users	Seats	Google-only SSO on Pro
Flagsmith	Start-Up, billed yearly	$500 on Scale-Up, billed yearly	50,000 requests, 1 member	Team members and requests	$50 per extra member, yearly billing
LaunchDarkly	Foundation, pay as you go	$833 billed yearly	Developer: 5 connections and 1K client-side users	Client-side users and server connections	$10 per connection beyond 5

PostHog and Statsig come out free because their free tiers absorb flag traffic at this size. The events they meter elsewhere are where their bills grow, and that is covered below.

What the scenario assumes

• 10 developers. Seats cost money at GrowthBook and Flagsmith only. LaunchDarkly, ConfigCat, PostHog and Statsig charge nothing per seat.
• 100,000 monthly active users on a client SDK. LaunchDarkly bills every 1,000 of them. ConfigCat bills downloads, and PostHog and Statsig bill requests and events.
• 3 server connections in one production environment. That sits inside the first five connections LaunchDarkly includes on Foundation.
• Serverless and short-lived processes. They are billed by connection time, so a function-heavy stack changes the bill. The serverless platforms ranking covers where those workloads run.
• 50 flags. Only ConfigCat caps flags on its pricing page, at 100 on Pro.
• 100,000 flag requests a month, one per user. That is the low end for a client app that checks flags more than once a session, and request-metered plans scale with it.
• Excluded: product analytics, session replay and experiments that send their own events. Each platform meters those differently, and they can change the ranking.

At 100,000 users, PostHog's 1 million free requests cover 10 requests per user a month before anything is billed. Statsig's 2 million free events work out to about 20 per user a month at this size, and every metered event counts toward that, including the product events you log.

How much does LaunchDarkly cost at 100,000 users?

LaunchDarkly's Developer plan is free, with unlimited seats, five server connections and 1,000 client-side users a month included. That covers a prototype or a small app, not a product with 100,000 users. Foundation is pay as you go, with no seat fees. Its pricing card lists $8.33 per 1,000 client-side monthly active users, and its plan table lists $10 per 1,000 for the same unit.

At the card rate, 100,000 users is 100 blocks of 1,000, which comes to $833 a month, or $9,996 a year, billed yearly. At the table rate the same users cost $1,000 a month. This page uses the card rate because it is the lower figure, and the gap matters. Every extra 1,000 users adds $8.33 to $10 a month, while adding developers adds nothing.

The three server connections sit inside the five that Foundation includes, so they add nothing here. Enterprise is quote-only, and Guardian, its release safety add-on, is priced separately.

What is the cheapest LaunchDarkly alternative?

PostHog and Statsig are the cheapest for flags alone at this scenario. Both free tiers hold until your product events grow. Among the paid plans, ConfigCat Pro is the cheapest from four developers upward, because its seats and users cost nothing. Cloud free-tier limits are compared in cloud free tiers compared.

Below four developers the picture changes. Three developers can run GrowthBook's free Starter plan, which allows up to three users. Flagsmith's Start-Up plan is billed yearly and includes three members.

Cost by team size

Developers	LaunchDarkly	PostHog	Statsig	ConfigCat	GrowthBook	Flagsmith
3	$833	Free	Free	$110	Free (Starter)	$40 (Start-Up, billed yearly)
10	Same	Free	Free	Same	$400	$500 (Scale-Up, billed yearly)
25	Same	Free	Free	Same	$1,000 (Pro)	Quote only (Scale-Up holds 20)

Monthly list cost at 100,000 users and 50 flags, in US dollars. Free means the allowance covers the scenario with no charge. LaunchDarkly and ConfigCat do not change with team size.

Two crossovers matter. GrowthBook Pro passes LaunchDarkly at 21 developers, at $840 against $833, because its price rises with every seat. Flagsmith's Scale-Up stays under LaunchDarkly up to 16 developers, at $800, and passes it at 17, at $850.

Is GrowthBook cheaper than LaunchDarkly?

Yes, until the seat count catches up. GrowthBook Pro charges $40 per seat a month for up to 30 users, so 10 developers pay $400, under half of LaunchDarkly's bill at this scale. GrowthBook's Starter plan is free for up to three users, with unlimited flags and experiments.

Pro includes 2 million CDN requests a month, which is 20 per user at this scenario, and charges $10 for each extra million. SSO on Pro is Google only. SAML and SCIM sit on the quote-only Enterprise plan.

Vendor by vendor: what PostHog, Statsig, ConfigCat and Flagsmith charge beyond the table

PostHog

PostHog bills a flag request as one feature flag evaluation, from the client or the server. The first million a month are free, experiments bill on the same meter, and the next band costs $0.0001 a request. The free plan needs a close read. Past its limits, flags return a quota-limited default response instead of billing, while pay-as-you-go charges for usage above the allowance.

Product analytics is a separate meter, with 1 million events free and then $0.00005 per event in the next band. PostHog's free plan also includes 100,000 exceptions of error tracking. For dedicated tools, see the error tracking tools ranking and the Sentry review. Neither plan charges per seat. The paid plan adds six projects and seven years of data retention.

Statsig

Statsig's Developer plan is free, with unlimited seats, unlimited flag and config checks, and 2 million metered events a month. The metering rule matters more than the free limit. Statsig charges for a flag exposure only when Metric Lifts are switched on and the flag is in a partial rollout. Exposures at 0% or 100% are not charged by default.

Logged events count toward the 2 million, so a product that sends many events uses the allowance quickly. Past it, Developer keeps gates and configs running but stops metric lift calculations. Pro is $150 a month with 5 million events included, then $0.05 per 1,000 events. Source: Statsig pricing.

ConfigCat

ConfigCat says its Forever Free plan has the same feature set as the paid plans. That holds for features but not for limits. The free plan allows 10 flags, two environments and 5 million config downloads a month, so 50 flags need Pro. Pro is $110 a month, with 100 flags, 25 million downloads and 100 GB of network traffic. It charges nothing for seats or monthly active users, and annual billing saves up to 10%, per the page. Smart, at $325 a month, removes the flag cap. Source: ConfigCat pricing.

Flagsmith

Flagsmith's free plan allows 50,000 requests and one team member, so this scenario outgrows it. Start-Up costs $40 a month billed yearly ($45 monthly) and covers 1 million requests and three members. Beyond three members, the plan is Scale-Up at $250 a month billed yearly ($300 monthly), with five members included. Up to 20 members cost $50 each a month on yearly billing ($60 monthly). Extra API calls cost $50 per million.

Above 20 members, Flagsmith quotes an Enterprise plan, which includes self-hosting. Source: Flagsmith pricing.

When LaunchDarkly is still the right answer

LaunchDarkly's case is governance more than price. Its Enterprise plan adds custom roles and teams, workflows with scheduling and approvals, and SCIM user provisioning. Guardian adds guardrail metrics and automatic rollback on top of Enterprise. If your release process depends on those controls, the cheaper tools above need extra work to match them. If it does not, price should decide.

Stay on the free Developer plan while you have 1,000 or fewer client-side users, and reprice before you pass that limit. Teams often connect flag changes to monitoring, so the best monitoring tools ranking is worth a look before you pick a replacement. If flags ship through a pipeline, the CI/CD tools ranking covers that side.

Methodology

• Every price comes from the vendor's own pricing page, read on October 10, 2026, in US dollars. Annual figures are the monthly price times 12.
• The scenario and the arithmetic are ours. Each vendor is priced on its own billing unit, and the assumptions are listed above.
• Where a vendor lists two prices, both are shown: LaunchDarkly's card rate and table rate, and Flagsmith's yearly and monthly prices.
• Plans that need a sales quote stay out of the ranking.
• The first-party figure comes from Toolradar's live feature flag ranking, checked October 10, 2026.
