LaunchDarkly

Enterprise default for feature flags, experimentation, and progressive delivery.

By Catamorphic Co. (LaunchDarkly) · Founded 2014 · Oakland, CA · private

LaunchDarkly is the market-leader feature flag platform, founded 2014 by Edith Harbaugh and John Kodumal, last valued at $3B+ in the Series D in August 2021. The product spans server-side and client-side SDKs across 25+ languages, advanced targeting rules, percentage rollouts, experimentation, and AI Configs (launched 2024) for managing prompt and model variants. Strengths: deepest governance, audit, approval workflows, and enterprise security posture in the category, the broadest integration ecosystem, and battle-tested at extreme scale (Atlassian, IBM, NBC, CircleCI). Trade-offs: pricing has escalated meaningfully across 2024-2025, six-figure renewals are now standard at the 200+ engineer band, MAU-based pricing creates surprise bills for consumer apps, and the 2024 push into experimentation and AI Configs has pulled product velocity away from core flagging.

Visit LaunchDarkly Vendor pricing Compare to Statsig
Best for

Mid-market and enterprise (200-50,000+ employees) needing deep governance, regulated-industry audit trails, and the broadest SDK + integration coverage, willing to pay enterprise pricing.

Worst for

Cost-conscious mid-market (ConfigCat or Flagsmith 50-70% cheaper), open-source-leaning teams (Unleash or GrowthBook better), or consumer apps with high MAU volumes (DevCycle or Statsig more predictable).
