LaunchDarkly plans
| Plan | Price | What it covers |
|---|---|---|
| Developer | $0/month | Free forever, no credit card. Unlimited seats and feature flags, A/B tests, ~5,000 AI runs/month with no overages, 10M logs/traces, 14-day data retention. |
| Foundation | $10 per service connection/mo (or $8.33 per 1K client-side MAU/mo) | Billed annually. Unlimited projects, scalable observability/experimentation, AgentControl AI runs at $5 per 1K beyond the 5,000 baseline, 30-day data retention. |

- Expensive for small teams and startups; per-seat/per-connection costs are a frequent complaint and median enterprise contracts run ~$72k/year
- Pricing model is complex and hard to predict, layering service connections, per-1K MAU charges, and metered add-ons for experimentation, session replay, and AI runs
- Provisioning seats is reported as a recurring friction point due to cost

- Request-based billing means high-traffic client-side evaluation can get expensive without adopting local evaluation
