Build vs Buy: The Real Cost of Feature Flags

Buy: LaunchDarkly Pro

  • 10 seats: $120/mo ($1,440/yr)
  • Setup time: 1 to 2 hours (install SDK, create first flag)
  • Maintenance: Zero (fully managed)
  • Includes: Targeting, scheduling, audit logs, SSO, experimentation
  • Reliability: 99.99% uptime SLA

Build: Self-Hosted (Unleash OSS)

  • Infrastructure: $50 to $200/mo (cloud hosting)
  • Setup time: 40 to 80 hours ($4,000 to $8,000 at $100/hr)
  • Maintenance: 2 to 5 hours/month ($200 to $500/mo)
  • Includes: Basic flags, targeting. No experimentation, limited audit.
  • Reliability: Depends on your infrastructure team

The math: For a 10-person team, LaunchDarkly Pro costs $1,440 per year. Self-hosting Unleash costs roughly $3,000 to $6,000 in setup plus $3,000 to $8,400 per year in infrastructure and maintenance. LaunchDarkly is cheaper for teams under 20 flag managers when you include engineering time costs. Beyond 20 seats, the per-seat cost ($2,880+ per year) starts to exceed self-hosting costs, especially if you already have infrastructure and DevOps expertise.

Experimentation (MAU) Pricing: The Hidden Cost

LaunchDarkly's experimentation feature (A/B testing with flags) charges by Monthly Active Users tracked. This can become the most expensive component for products with large user bases.

MAUIncluded in ProEst. Additional Cost/mo
10,000Yes$0
25,00010K free$150 to $450
50,00010K free$400 to $1,200
100,00010K free$900 to $2,700
500,00010K free$4,900 to $14,700

Enterprise plans include unlimited MAU for experimentation, which is why high-traffic products often go directly to Enterprise. The breakeven point is typically around 100,000 MAU where the experimentation surcharge exceeds the Pro plan cost.

Frequently Asked Questions

How much does LaunchDarkly cost?▼
LaunchDarkly has three tiers. The Developer plan is free for 2 seats with 1 project and 2 environments. The Pro plan costs $12 per seat per month with unlimited seats, projects, and environments. The Enterprise plan has custom pricing. Experimentation (A/B testing) adds additional costs based on Monthly Active Users tracked.
Is LaunchDarkly free?▼
LaunchDarkly offers a free Developer plan for up to 2 seats. It includes all flag types, 1 project, 2 environments, and 1,000 MAU for experimentation. The free plan is suitable for personal projects and evaluation but not for production teams with more than 2 developers managing flags.
How much does LaunchDarkly experimentation cost?▼
Experimentation pricing is based on Monthly Active Users (MAU). Pro includes 10,000 MAU. Additional MAU costs approximately $0.01 to $0.03 per MAU per month. For a product with 100,000 MAU, that is $1,000 to $3,000 per month on top of seat costs. Enterprise includes unlimited MAU for experimentation.
Do all developers need LaunchDarkly seats?▼
No. Only developers who create, modify, or manage feature flags need seats. Developers who only read flag states through the SDK do not need seats. On Enterprise, read-only users are explicitly free. A 50-person engineering org where only 15 manage flags pays $180 per month on Pro, not $600.
Is LaunchDarkly worth it compared to open source?▼
LaunchDarkly is worth it when the total cost of self-hosting (infrastructure, setup, maintenance) exceeds the subscription. For teams with fewer than 20 flag managers, LaunchDarkly Pro often costs less than maintaining an open-source alternative like Unleash when you factor in engineering time. For larger teams, the per-seat cost adds up and open-source becomes more cost-effective.
Does LaunchDarkly add latency?▼
LaunchDarkly evaluates flags at the edge using Workers, with sub-10ms evaluation time. The SDK initializes once and caches flag values locally, so subsequent evaluations are essentially zero-latency. Flag changes propagate to connected SDKs in under 200ms via streaming connections.
What SDKs does LaunchDarkly support?▼
LaunchDarkly supports all major languages and platforms: JavaScript, React, Node.js, Python, Java, Go, Ruby, .NET, PHP, Swift, Kotlin, React Native, Flutter, and more. Server-side SDKs connect directly to LaunchDarkly. Client-side SDKs use a relay proxy or edge workers for evaluation.
Does LaunchDarkly require annual billing?▼
Pro requires annual billing. Monthly billing is not available on the Pro plan. Enterprise billing terms are negotiated during the sales process, with annual contracts as the standard. The Developer (free) plan has no billing commitment.
