LaunchDarkly Alternatives in 2026: Statsig, PostHog, GrowthBook, and ConfigCat Compared

This ToolPick decision brief compares LaunchDarkly against its four most common alternatives — Statsig, PostHog, GrowthBook, and ConfigCat — using pricing and plan details pulled directly from each vendor's official pricing page on July 12, 2026. The goal is not to declare one universal winner. The five tools solve overlapping but distinct problems, and the right pick depends on whether you need flags alone, flags plus analytics, or flags plus enterprise release governance.

Quick Decision

If you are choosing a first feature-flag tool and don't already have a strong reason to pick something else, start with Statsig. Its free tier covers 2 million events a month with unlimited seats, and its paid Pro tier is a flat $150 a month rather than a per-seat or pure usage-based bill, which makes budgeting predictable while your usage grows.

Deviate from that default in three specific cases. If your team already runs PostHog for product analytics or session replay, add its feature flags instead of paying for a second vendor — the free tier alone covers 1 million flag requests a month. If you want an open-source or self-hosted option, or you specifically want to keep flag data inside your own data warehouse, GrowthBook is the only tool on this list built around that model. And if your actual requirement is enterprise governance — SAML/SCIM, custom roles, guardrail-based automatic rollback — that is a LaunchDarkly or GrowthBook Enterprise conversation, not a self-serve pricing-page decision.

What Each Tool Actually Is

• LaunchDarkly — the category incumbent. Feature flags plus observability, release automation, and guardrail-based rollback, aimed at organizations that need formal release governance.
• Statsig — flags, experimentation, and product analytics bundled into one flat-rate product, positioned as an all-in-one alternative rather than a flags-only tool.
• PostHog — an open-source-rooted product analytics platform where feature flags are one product among several (analytics, session replay, surveys), billed on the same usage-based account.
• GrowthBook — an open-source feature flagging and experimentation platform with both a hosted cloud plan and a genuinely free self-hosted edition.
• ConfigCat — a flags-and-config-delivery specialist with no built-in analytics or experimentation product, priced on fixed monthly tiers rather than per-seat or pure usage.

Free Tier Comparison

Two of the five vendors publish a genuinely usable free tier for a hosted product: PostHog (1 million feature-flag requests a month before any charge) and Statsig (2 million events a month, with unlimited seats even on the free plan). ConfigCat's Forever Free tier is real but capped tightly on functionality — 10 feature flags, 2 environments, and 2 products — which makes it better suited to a small side project than a growing product team. GrowthBook's free tier only reaches "unlimited" if you self-host and bring your own infrastructure and data warehouse; its hosted Cloud Starter plan is capped at up to 3 seats.

Paid Plan Pricing, Vendor by Vendor

LaunchDarkly: usage-based, billed annually

LaunchDarkly's free Developer plan covers unlimited seats and unlimited feature flags, but caps at 5,000 AI runs and 5,000 session replays a month with 14-day data retention. Above that, the Foundation tier is not a flat monthly number — it is billed yearly and priced either $10 per service connection a month or $8.33 per 1,000 client-side monthly active users a month, plus $5 per 1,000 AI runs beyond the free 5,000. Enterprise and the newer Guardian tier (which adds automatic pause-and-rollback release monitoring) are both custom-quoted, so there is no published number to compare against the other four vendors at that level.

Statsig: flat $150/month at the Pro tier

Statsig's Developer plan is free for 2 million events a month with unlimited seats and unlimited flag and config checks. The Pro plan is a flat $150 a month, including 5 million events, with overage priced at $0.05 per additional 1,000 events. Enterprise moves to custom event- or experiment-based contracts with volume discounts, plus warehouse-native deployment and HIPAA eligibility for regulated teams.

PostHog: pure usage-based, shared across products

PostHog's feature flags are free for the first 1 million requests a month. Past that, pricing steps down as volume grows: $0.0001 per request from 1-2 million, $0.000045 per request from 2-10 million, $0.000025 per request from 10-50 million, and $0.00001 per request beyond 50 million. Because PostHog bills usage across its whole platform rather than flags in isolation, a team already spending on PostHog analytics may find flags essentially free at the margin; a team adopting PostHog for flags alone is buying into a broader product suite it may not otherwise need. See our separate PostHog pricing breakdown for the full cross-product cost model.

GrowthBook: per-seat cloud, unlimited self-hosted

GrowthBook's Cloud Starter plan is free for up to 3 seats with unlimited feature flags and experiments, capped at 1 million CDN requests and 5GB of bandwidth a month. The Pro plan moves to $40 per seat a month for up to 50 seats, adding a visual editor, multi-arm bandits, safe rollouts, and customizable dashboards. Enterprise is custom-quoted for both the hosted and self-hosted paths. The open-source self-hosted edition is free with unlimited users and unlimited flags and experiments, provided you supply your own warehouse and hosting.

ConfigCat: the only published fixed-price ladder

ConfigCat is the only vendor on this list with a full public price ladder above the free tier, billed monthly by default: Pro at $110/month (100 flags, 25 million downloads), Smart at $325/month (unlimited flags, 250 million downloads, unlimited segmentation), Enterprise at $900/month (1 billion downloads, 99.99% SLA), and Dedicated at $4,500/month for a private managed cloud handling 6 billion-plus downloads a month. ConfigCat's pricing page also offers an annual-billing toggle, and the discounted annual rate was not re-verified for this comparison — confirm the current annual price directly on the pricing page before budgeting, the same way LaunchDarkly's Foundation tier is disclosed as billed yearly above. All ConfigCat plans include unlimited seats, unlimited monthly active users, and unlimited feature-flag reads — the tiers scale on download volume and platform features, not on headcount.

Which Tool Fits Which Team

For a team already invested in a specific ecosystem, the picture changes. Teams already running PostHog for session replay or product analytics get flags close to free at the margin, since PostHog bills usage across the whole account rather than charging a separate flags subscription — see our PostHog review for how the flags product fits alongside PostHog's other tools. Teams that want to keep flag and experiment data inside their own infrastructure, or that already run an open-source-first stack, are better served by GrowthBook's self-hosted edition, which is the only genuinely unlimited free option on this list outside of a hosted free tier. Teams whose actual blocker is compliance — SAML/SCIM, custom roles, data retention past LaunchDarkly's 30-day Foundation-tier default, guardrail-based automatic rollback — should treat this as a LaunchDarkly Enterprise/Guardian or GrowthBook Enterprise conversation rather than a self-serve pricing decision, since none of the published numbers above apply at that tier. Our broader feature flag tools shortlist covers a few additional options if none of these five fit the workflow.

Migrating Off LaunchDarkly

Three of the four alternatives publish a dedicated LaunchDarkly import tool. GrowthBook has a two-step importer built into its dashboard: paste a LaunchDarkly API token, preview the projects, environments, and flags it finds, then import them in roughly a second per flag. ConfigCat has an "Import from LaunchDarkly" wizard reachable from the organization menu that auto-creates matching products and environments and translates targeting rules on a best-effort basis, flagging anything it could not translate cleanly for manual review. Statsig ships both an open-source migration script (which covers every environment) and a console-based import wizard (which covers production only), each generating a report of what migrated successfully. PostHog is the outlier — it has no built-in importer, so moving to it means pulling flag data out of the LaunchDarkly API and recreating flags with a script against PostHog's API by hand. Whichever path applies, wire the new SDK into a staging environment first, run both flag providers in parallel for a short cutover window so you can compare evaluation results, and don't remove the LaunchDarkly SDK until that parallel run confirms parity. Budget real review time even with an automated importer — targeting-rule edge cases and toggle behavior rarely translate perfectly — and confirm the current state of each vendor's import tooling against their live docs before you commit to a cutover date, since flag-management vendors change migration tooling more often than they announce it.

Red Flags Before You Commit

• Treating a per-seat price (GrowthBook Pro, LaunchDarkly's per-connection Foundation tier) as flat when your team is still growing — do the math at your projected headcount, not your current one.
• Assuming a usage-based plan (PostHog, LaunchDarkly Foundation, Statsig overage) will stay near the free-tier number once a product actually ships and traffic grows.
• Picking a flags-only tool like ConfigCat and discovering later that the team also wanted built-in experimentation, which means paying for and integrating a second product.
• Assuming an Enterprise tier price without asking for a quote — every vendor in this comparison keeps Enterprise pricing off the public page, and the gap between a mid-tier plan and Enterprise can be large.
• Assuming an automated importer (GrowthBook, ConfigCat, or Statsig all offer one) means zero review — each tool's own docs flag translation issues and toggle-behavior edge cases that still need a human pass, and a real parallel-run window before you remove the LaunchDarkly SDK.

Final Recommendation

There is no single best LaunchDarkly alternative — there is a best alternative for a specific team's constraints. Statsig is the strongest general-purpose default because of its flat Pro pricing and generous free tier. PostHog is the right call if flags can ride on analytics spend you already have. GrowthBook is the right call if open source, self-hosting, or warehouse-native data ownership actually matters to the team. ConfigCat is the right call if the requirement is genuinely flags-only and a fixed, published monthly price matters more than an all-in-one product. And LaunchDarkly itself remains the right call when the requirement is specifically its enterprise release-governance tooling — at which point price stops being the deciding factor and the custom Enterprise quote is the number that matters.

Because every vendor here revises pricing and free-tier limits without much notice, re-check the official page linked below before finalizing a budget, especially if more than a few weeks have passed since this article was checked.
