About the feature flags & experimentation platforms category
Feature flag platforms in 2026 split into four distinct pricing models. Per-seat + usage (LaunchDarkly: $12/service connection + $10/1K client-side MAU) scales linearly with team AND traffic — elegant but expensive at scale. Flat-tier with usage caps (ConfigCat: $110 Pro / $325 Smart / $900 Enterprise monthly, SDK-call-based) is the developer-friendly middle ground. Per-seat only (Unleash: $75/seat/month with 53M requests included) is predictable but can't flex without seat upgrades. Events-based (Statsig: Free 2M events / Pro $150 for 5M + $0.05/1K overage) is the analytics-native model. Split.io's 2024 Harness acquisition (now 'Harness FME') collapsed public pricing into Enterprise-only quote — a significant category shift that pushed many mid-market customers toward ConfigCat and Statsig. The strategic question is no longer 'which flag tool' but 'do you want flags-only (ConfigCat, Unleash), flags + experimentation (LaunchDarkly, Statsig), or flags bundled with a broader DevOps/observability suite (Harness FME)?'
How to choose between feature flags & experimentation platforms options
First: what's your team size and traffic profile? Solo/small team with modest traffic (≤5M SDK calls/mo): ConfigCat Forever Free (10 flags, 5M calls) or Statsig Developer (2M events, unlimited seats) — both genuinely useful free tiers. Growing team (5-20 devs, 5-50M calls/mo): ConfigCat Pro $110/mo flat or Statsig Pro $150/mo — predictable costs, no MAU surprises. Scaling company (20+ devs, client-side SDKs, many end users): LaunchDarkly Foundation pricing is honest but expensive — $10/1K client-side MAU means 100K MAU = $1,000/mo in MAU alone + service connections. Second: do you need experimentation (A/B testing with statistical significance)? Statsig and LaunchDarkly have it natively. ConfigCat and Unleash focus on flags-first; for experimentation you'd add a separate tool. Third: self-hosting requirement? Unleash is the clear answer — open source core + commercial self-hosted Enterprise. LaunchDarkly/ConfigCat are cloud-only (some relay agents). Fourth: DevOps suite consolidation? If you're already paying Harness for CI/CD/IaC, adding FME (Split.io successor) may be cheaper than standalone — if you're not, Harness's quote-only enterprise model makes it a poor fit. Fifth: compliance requirements? LaunchDarkly, Unleash, and Harness all offer SOC2/HIPAA/FedRAMP-capable tiers; ConfigCat and Statsig SOC2 but lighter on regulated-industry features.
