6 Alternatives to LaunchDarkly in 2026
Teams leave LaunchDarkly when the bill, built from service connections, client-side users and AI runs, becomes hard to predict, when governance features sit behind Enterprise, or when they want to host flags themselves. People usually move to Statsig, PostHog or GrowthBook, or to open-source options such as Unleash.
Why people look for an alternative to LaunchDarkly
The bill has several meters
LaunchDarkly's Foundation plan charges $10 per service connection per month on yearly billing ($12 monthly) after 5 free, and other usage such as client-side users and AI runs is metered too. Forecasting a year means counting each meter separately.
Governance and compliance rise with the contract
SCIM, custom roles, required approvals, SSO/SAML, audit logging and SOC2/ISO compliance are listed under Enterprise, which has custom pricing and no dollar figure on the page. Foundation only adds approval requests for flags and experiments.
Retention and limits on the entry tiers are short
Developer keeps data for 14 days and stops ingesting at the 5K AI run limit, with 1 project and 3 environments. Foundation keeps 30 days. Enterprise reaches 100+ days, so audit-minded teams are pushed up the ladder.
The best LaunchDarkly alternatives
- 1
Statsig
Statsig combines flags with experimentation, product analytics and session replay, and it can run on your own warehouse. Pro is $150 a month with 5M events included. Its terms name Amplitude, Inc. as the contracting party while the site footer says Statsig, LLC, so confirm the legal entity.
Switch if you Switch if experiments and product analytics matter as much as the flags and you want a flat Pro price.
- 2
PostHog bundles analytics, session replay, flags, experiments and error tracking, with a monthly free tier that includes 1M feature flag requests. You pick a US or EU cloud region at signup. Beyond the free tier, billing is usage-based with no flat price published.

- 3

Switch if you Switch if your data team already owns a warehouse and wants statistics run against it.
- 4
Unleash
Unleash is a Norwegian open-source project that bills by seat, $75 per seat per month on Pay-As-You-Go, and never charges per flag evaluation. Open source is capped at 1 project, 2 environments and 5,000 flags, without SSO or change requests.
Switch if you Switch if traffic spikes drive your LaunchDarkly bill and a headcount-based invoice would be steadier.
- 5
Flagsmith
Flagsmith offers hosted cloud, private cloud, self-hosted and air-gapped installs on an open-source core. The Start-Up plan is $45 a month ($40 yearly) priced on requests, though roles, change requests and audit logs begin at the $300 Scale-Up plan.

- 6
ConfigCat
ConfigCat, a Hungarian service, charges by config downloads and not by seat, connection or evaluation. Pro is $110 a month, the free plan stops at 10 flags and 2 environments, and an EU-only CDN setting is available. It has no experiment statistics.
Switch if you want plain flags at a flat monthly price with EU-only data placement.
Before you switch away from LaunchDarkly
Inventory your flags before anything else. Export the list from LaunchDarkly with their targeting rules, and mark which are permanent configuration and which are short-lived releases, since you can retire the latter instead of migrating them. Check whether you use experiments, holdouts or AgentControl evals, because only some alternatives replace those. Note which SDKs you run, and whether the replacement supports OpenFeature if you want an easier future exit. Plan a period where both systems evaluate in parallel, and confirm that audit logs and approval history, which LaunchDarkly keeps for 14 to 100+ days by plan, are exported before you cancel.

Frequently asked questions
Is LaunchDarkly's Developer plan really free?
Yes, the pricing page lists Developer at $0 per month with no credit card, unlimited seats and flags. The limits are in usage: 5 service connections, 1K client-side MAU, 5K AI runs, 1 project and 3 environments, and 14-day data retention. Teams outgrow it through connections and environments, not flag count.
What does a LaunchDarkly service connection mean for cost?
A service connection is the billing unit for server-side use. Foundation includes 5 free, then charges $10 each per month on yearly billing or $12 monthly, with 17% off usage rates for annual billing. A team that runs many microservices should count each deployed service and environment before comparing it with seat-based tools.
Which LaunchDarkly alternative handles experiments best?
Statsig and GrowthBook are the closest in focus. Statsig bundles experimentation with analytics and session replay and offers warehouse-native deployment on Enterprise. GrowthBook runs its statistics against your own warehouse. PostHog also runs experiments, billed together with feature flags. Check the statistical methods against what your analysts expect.
Can I self-host a LaunchDarkly replacement?
Yes. Unleash, Flagsmith and GrowthBook all offer open-source editions that you host yourself, and Flipt does as a standalone binary storing flags in Git. Each caps features differently: Unleash open source has no SSO or change requests, and GrowthBook's free self-hosting is limited to one project.
